Constructive Analysis of Cyclic Circuits ( EDTC , Paris , March 1996 )
Traditionally, circuits with combinational loops are found only in asynchronous designs. However, combinational loops can also be useful for synchronous circuit design. Combinational loops can arise from high-level language behavioral compiling, and can be used to reduce circuit size. We provide a symbolic algorithm that detects if a sequential circuit with combinational loops exhibits standard...
متن کاملSequential Test Generation Based on Circuit Pseudo-Transformation
The test generation problem for a sequential circuit capable of generating tests with combinational test generation complexity can be reduced to that for the combinational circuit formed by replacing each FF in the sequential circuit by a wire. In this paper, we consider an application of this approach to general sequential circuits. We propose a test generation method using circuit pseudo-tran...
متن کاملAnalysis of Combinational Cycles in Sequential Circuits
This paper addresses the analysis of combinational cycles in synchronous, sequential circuits. A circuit that has a com-binational cycle does not necessarily have unstable output behavior: the cycle may be \false" for all reachable states and possible input sequences, or the unstable behavior on the cycle may not aaect the outputs. We provide a procedure to determine whether a circuit produces ...
متن کاملApplications of Fuzzy Program Graph in Symbolic Checking of Fuzzy Flip-Flops
All practical digital circuits are usually a mixture of combinational and sequential logic. Flip–flops are essential to sequential logic therefore fuzzy flip–flops are considered to be among the most essential topics of fuzzy digital circuit. The concept of fuzzy digital circuit is among the most interesting applications of fuzzy sets and logic due to the fact that if there has to be an ultimat...
متن کاملPower Supply Noise Suppression via Clock Skew Scheduling
Simultaneous switching events in the clock lines and the signals passing through sequential and combinational logic elements cause large and voltage variations in the power and ground network. This is known as power supply noise and it affects the performance and reliability of the entire circuit. In this paper, we propose an algorithm that performs clock skew scheduling to minimize the number ...
