Proceedings of ASPDAC/VLSI Design 2002. 7th Asia and South Pacific Design Automation Conference and 15h International Conference on VLSI Design, Los Alamitos, CA. IEEE Comput. Soc., pp.31722,2002.
[Abstract: In this paper, we use circuit simulations to characterize the effects of technology scaling on the metastability parameters of CMOS latches used as synchronizers. We perform this characterization by obtaining a synchronization error probability curve from a histogram of the latch delay. The main metastability parameters of CMOS latches are tau /sub m/ and T/sub w/. tau /sub m/ is the exponential time constant of the rate of decay of metastability and T/sub w/ is effective metastability window size at a normal propagation delay. Both parameters can be extracted from a histogram of the latch delay. This paper also explains a way to calibrate the simulator for accuracy. The simulations indicate that tau /sub m/ scales better than the technology scale factor. T/sub w/ also scales down but its factor cannot be estimated as well as that of tau /sub m/. This is because T/sub w/ is a complex function of signal and clock edge rate and logic threshold level.]

Proceedings of the Sixteenth National Radio Science Conference. NRSC'99, Ain Shams Univ., Cairo, Egypt, pp. C13/14, February, 1999.
[Abstract: Many digital circuits with asynchronous inputs are susceptible to failure even when all their components are faultfree. They may fail as a result of metastable operation when their inputs have critical timing combinations. This paper addresses a novel priority arbiter architecture to solve the metastability problem. SPICE simulation is used to verify its performance and correctness. In contrast to other arbiters, the results showed that this new design has better immunity against metastable operation.]

ICECS 2002. 9th IEEE International Conference on Electronics, Circuits and Systems. IEEE. Vol.2, pp.517520, September, 2002.
[Abstract: This paper describes a globally asynchronous, locally dynamic system (GALDS) design paradigm. In a GALDS design, many synchronous blocks are interconnected using dedicated asynchronous links. Each synchronous block is associated with a local clock generator and features dynamic frequency scaling in order to utilize the least possible power for the required performance to be achieved. Two different asynchronous structures are explored in this paper and they each feature high throughput, modular design and high tolerance to metastability errors that occur when communicating between clock domains. These structures utilize a 4phase dual track asynchronous control circuit to control either a single direction FIFO with data traveling uniquely in one direction or a bidirectional FIFO that is capable of transmitting data simultaneously in both directions by precisely controlling when data has access to a common, shared datapath. These structures have been created in TSMC's CMOSP18 technology.]

"Clock jitter and quantizer metastability in continuoustime deltasigma modulators",
IEEE Transactions on Circuits & Systems IIAnalog & Digital Signal Processing, Vol. 46, No. 6, pp. 661676, June, 1999.
[Abstract: The performance of continuoustime (CT) deltasigma modulators ( Delta Sigma M's) suffers more severely from time jitter in the quantizer clock than discretetime designs. Clock jitter adds a random phase modulation to the modulator feedback signal, which whitens the quantization noise in the band of interest and hence degrades converter resolution. Even with a perfectly uniform sampling clock, a similar whitening can be caused by metastability in the quantizer: a real quantizer has finite regeneration gain, and thus, quantizer inputs near zero take longer to resolve. This paper quantifies the performance lost due to clock jitter in a practical integrated CT Delta Sigma M clocked with an onchip voltagecontrolled oscillator. It also characterizes metastability in a practical integrated quantizer using the quantizer output zerocrossing time and rise time as a function of both quantizer input voltage and the slope of the input voltage at the sampling instant, and predicts the maximumachievable performance of a practical CT Delta Sigma M given jitter and metastability constraints.]

1998 IEEE International Conference on Electronics, Circuits and Systems. Surfing the Waves of Science and Technology. IEEE. Vol. 3, pp. 453456, September, 1998.
[Abstract: The word error rate (WER) of an A/D converter quantifies the probability that a wrong output code occurs because of metastability, intrinsic noise or aperture uncertainty. It can be measured in realtime, as it is customary for very low WER converters, or by post processing, when the WER is more relevant. In the paper the possible causes of inaccuracy are analyzed. First, the existing methods are reviewed, then the errors which may arise from the conventional analysis of experimental data are discussed, and it is shown that these errors can be removed in the case of post processing. Finally, the requirements on the test bench noise are discussed in connection with the qualified error level (i.e. 1, 2, 4, .., 16 LSB) and with the expected error rate.]

[Abstract: Realtime digital systems and asynchronous computer systems have an inherent risk of occasional failures due to metastability in various components used to control datatransfers. This possibility has been known for a long time, although it is sometimes forgotten or overlooked. There is renewed interest in asynchronous computer systems because of the prospects they offer for lower power operation and improved electromagnetic compatibility compared to conventional fully synchronous systems. As a result, design approaches to minimise metastability effects need to be adopted. Recent increased understanding of nonlinear dynamics and the availability of software for the accurate simulation and visualisation of dynamic behaviour enables metastability to be investigated and demonstrated much more readily. This paper provides a mainlytutorial review of how metastability arises in various commonlyused components, illustrated with the results of simulations.]

True metastability is distinguished from the deterministic region. A worst case meantimebetweenfailure bound is established. A simple and accurate test method is presented. A simple jamb latch was used with driving circuits of two different strengths to determine the role of input strength on T/sub m/ and tau . The flipflop was fabricated on a 0.25 mu m CMOS process.]

[Abstract: We present a theory for metastability error power in successive approximation A/D converters. The traditional measure, BER, does not account for the error influence on signal quality, only the error rate. The metastability error is instead compared with noise, and a signaltometastabilityerrorratio, SMR, is suggested as a new measure, suppressing SMR below SNR imposes a gain requirement on the comparator.]

Proceedings of the 7th International Conference Mixed Design of Integrated Circuits and Systems. MIXDES 2000. Tech. Univ. Lodz, Poland, pp.275280, June, 2000.
[Abstract: Metastability has been long documented as a problem in digital systems with asynchronous inputs. This problem has been analyzed in CMOS latches using a 2nd order small signal model.

[Abstract: Metastability has been long documented as a problem in digital systems with asynchronous inputs. This problem has been analyzed in CMOS latches using a 2nd order small signal model. However, use of a third order model, taking into account that the effect of the feedback transistor is necessary for correct modeling of metastability. A new simulator was developed for this study. The results presented here show that when modeling a CMOS latch for metastability purposes, it is not sufficient to use a second order circuit that neglects the effect of the feedback transistor. While second order models are helpful in understanding how to model the circuit in the region, they do not provide sufficient information to accurately predict the essential parameter tau the maximum time at which the circuit may leave the metastable state. The only way to analyze such a circuit is to simulate it, using a simulator that combines small signal and large signal analysis. Future work on metastability will include modeling the feedback transistor as a resistor, and determining whether such a model is a reasonable simplification. The simulator can be modified easily to model small transistor geometry devices and to study the effect of large signal noise, such as ground and power supply bounce, on metastability. The model may also be applied to an interconnect model to improve delay and crosstalk simulations.]

[SUMMARY: In the design of a large highspeed computer, the size of the system leads to long cable delays for data transmitted between different parts of the machine. This problem and the interconnexion of a highspeed e.c.l. circuit family are discussed, and comment is made on future lines of development for technology in highspeed computers. Priority circuits in a large asynchronous system also present difficulties not usually encountered in smaller machines and a discussion of how these difficulties arise is presented.]

[Abstract: Synchronisation of two independently clocked processor units, or arbitration between two asynchronous units requesting access to a common resource, can cause serious time losses in a computer system. The ways in which these problems arise are considered, and a theoretical basis for calculation of the time losses is presented. The theory is then correlated with measurements on practical devices, and currently available methods for minimising the time loss are evaluated. Conditions necessary for prediction of the performance of synchronisers and arbiters are established and it is shown that design principles exist which allow the construction of systems with known reliability.]

[Abstract: Analog to digital (AD) converters with a fixed conversion time are subject to errors due to metastability. These errors will occur in all converter designs with a bounded time for decisions, and are potentially severe. We estimate the frequency of these errors in a successive approximation converter, and compare the results with asynchronous designs using both a fully speedindependent, and a bundled data approach. It is shown that an asynchronous converter is more reliable than its synchronous counterpart, and that the bundled data design is also faster, on average, than the synchronous design. We also demonstrate tradeoffs involved in asynchronous converter designs, such as speed, robustness to delay variations, circuit size and design scalability.]

[Abstract: Metastability in the comparators of high speed synchronous flash AD converters is a source of noise in the output. Pipelining can reduce metastability errors but can consume significant power in synchronous systems, and techniques have been described which aim to reduce the power, but can lead to nonlinearity. It is shown that power can also be reduced without loss of linearity by asynchronous micropipelining techniques which allow the comparison times to vary without a high probability of metastability noise. Other advantages resulting from asynchronous internal timing include a reduction in clock noise, and improved tolerance to process and interconnect delays.]

[Abstract: Analogdigital (AD) converters with a fixed conversion time are subject to errors due to metastability. It is shown that an asynchronous converter in which the conversion time is not bounded is faster, on average, than the synchronous design. Realtime applications require the data to be produced within a fixed time, and failures may occur with the long conversion times that can arise with fully asynchronous converters. For these applications, we show that an internally asynchronous bounded time converter is both faster and more reliable than a synchronous converter.]

[Abstract: This paper shows that the internal noise in a bistable exhibits a Gaussian distribution, and is close to the value expected from thermal agitation. We describe a random number generator based on this property that is capable of on chip integration, and is a primary source of high entropy data at 100 MHz. The device is held close to metastability by a feedback loop, and is therefore relatively insensitive to circuit asymmetries and drift. Measurements of postprocessed data from this source also show a relatively high bit rate and sequences of 2/sup 23/ bits are shown to pass stringent tests for randomness.]

[Abstract: Synchronization between independently clocked regions in a high performance system is often subject to latencies of more than one clock cycle. We show how the latency can be reduced significantly, typically to half the number of clock cycles required for high reliability, by speculating that a long synchronization time is not required. The small number of synchronization metastability times longer than normal are detected, and subsequent computations reevaluated, thus maintaining the reliability of the system.]

[Abstract: Present measurement techniques do not allow synchronizer reliability to be measured in the region of most interest, that is, beyond the first half cycle of the synchronizer clock. We describe methods of extending the measurement range, in which the number of metastable events generated is increased by four orders of magnitude, and events with long metastable times are selected from the large number of more normal events. The relationship found between input times and the resulting output times is dependent on accurate measurement of input time distributions with deviations of less than 10ps. We show how the distribution of D to Clock times at the input can be characterised in the presence of noise, and how predictions of failure rates for long synchronizer times can be made. Anomalies such as the increased failure rates in a master slave synchronizer produced by the back edge of the clock are measured.]

ISCAS'99. Proceedings of the 1999 IEEE International Symposium on Circuits and Systems VLSI, IEEE. Vol. 2, pp.516519, June, 1999.
[Abstract: Global synchronization has been commonly used to protect clocked I/O from data read failure due to metastability. For future high performance systemonchip design, global synchronization is more difficult as both frequency and chip size increase quickly. This paper addresses a mesochronous clocking (MC) strategy which can be implemented with three selftested selfsynchronization (STSS) methods for parallel data transfer between processing elements (PEs). Compared with global synchronization, MC has many advantages: lower process cost; less power dissipation in clock distribution; no limit in system scale; less delay in long distance data transfer; more simplicity and flexibility in design. The STSS implementations are also very simple and robust, and the metastability in data read is avoided because STSS is completely insensitive to both clock skew and data delay.]

[Abstract: In largescale and highspeed systems, global synchronization has been commonly used to protect clocked I/O from data read failure caused by metastability. There are many drawbacks with global synchronization, which will approach its physical limit in the future as system clock frequency and system scale increase simultaneously. Mesochronous clocking overcomes these drawbacks, but without a proper delay or phase control, a metastability problem occurs. Selftested selfsynchronization (STSS) was proposed to solve this problem. In this paper, we describe two STSS methods, STSS1 and STSS2, implemented by twophase input ports for parallel/serial data transfer. Measurements on a test chip for the two methods show that a data rate of 750 Mb/s is reached with 3.6V power supply in 0.6 mu m CMOS. Comparison is made between STSS1 and STSS3.]

[Abstract: In largescale and highspeed digital systems, global synchronization has frequently been used to protect clocked I/O from data failure do to metastability. Synchronous design style is widely used, easy to grasp and to implement, also well supported by logic synthesis tools. There are many drawbacks with global synchronization. Most important is the relationship between physical size and maximum clock frequency, which will approach its limit as clock frequency and system size increase simultaneously. The purpose of this proposed Globally Updated Mesochronous design style (GUMdesignstyle) is to overcome these drawbacks by identifying and allowing all single and bidirectional highspeed signal links needed, while still retaining the simplicity uncomplicated implementation and tool support. In this paper GUMdesignstyle is described, analysed and demonstrated. Experimental results from a largescale highspeed system using three 0.8 mu m BiCMOS chips are given. GUMdesignstyle is scaleable and suitable for future System on Chip (SoC) both on and between chips.]

[Abstract: Although an asynchronous reset is a safe way to reliably reset circuitry, removal of an asynchronous reset can cause metastability if not done properly. A proper way to design with asynchronous resets by adding the reset synchronizer logic and using a reset distribute buffer tree to allow asynchronous reset of the design and to ensure synchronous reset removal to permit safe restoration of normal design functionality was given in this paper.]

[Abstract: An analysis of the metastability of silicononinsulator (SOI) complementary metaloxidesilicon (CMOS) latches is presented, using partiallydepleted SOI devices with various bodyconnection topologies and an unbuffered latch. The metastability window, resolution time and time interval between the clock edge and the time t/sub meta/ are evaluated as functions of power supply and the type of bodyconnection topology. Simulations using SOISPICE show improved metastability behaviour for SOI specific bodyconnection topologies.]

[Abstract: This paper presents a method for evaluating the metastability of a flipflop circuit for random number generation applications. It is well known that digital circuits can exhibit metastable behavior when the input to a flipflop is asynchronous to the system clock. In the past, extensive research has been focused on eliminating metastability in digital systems. Here, we present some preliminary results of our research to exploit metastable behavior in sequential logic circuits to produce random bit streams for random number generation. In particular, we explore the idea of tapping the electronic noise present in Dtype flipflops to produce random bit streams for use as a onetime cryptographic keypad for encryption algorithms. This research will serve as a basis for further research into the verylargescaleintegration (VLSI) of random number generators (RNGs).]

[Abstract: Traditional synchronization methodologies have largely concentrated on the use of a global clock signal to maximize the functional integration possible on the chip. Unfortunately, distribution of a low skew clock signal over the entire die at current clock rates is becoming increasingly difficult. By using a combination of architectural design and delay insensitive data encoding, it is possible to ameliorate the interpatch penalties and take synchronization overhead into account. Extending this architectural modeling, it is also possible to account for other types of overhead, such as those due to Vdd changes between digital regions and analog or RF regions, thus enabling design optimizations for system on a chip applications. Finally, a potential methodology for containing metastability at synchronizer boundaries with relatively low latencies is proposed.]

[Abstract: Two asynchronous data communication mechanisms (ACMs) using selftimed circuits are presented. Mutual exclusion elements are used to concentrate potential metastability to discrete points so that it can be resolved entirely within the ACMs themselves. Selftimed circuits allow the minimisation of the interface between the reader and writer processes and the ACMs. Initial analysis shows that these VLSI solutions are more robust with regard to steering logic metastability, and can potentially run faster than solutions under fundamental mode assumptions. They are therefore more suitable for use in onchip multiprocessing systems.]

[Absract: We describe a new latch circuit designed to give a high performance in low voltage synchronizer applications. By increasing the latch current only during metastability, we can more than maintain the value of the metastability time constant, τ, without significantly increasing the power. Our circuit also reduces the variation of τ with Vdd and temperature, so that it has a lower τ at 50% Vdd than the conventional jamb latch has at 60% Vdd.]
