Formal equivalence checking process is a part of electronic design automation (EDA), commonly used during the development of digital integrated circuits, to formally prove that two representations of a circuit design exhibit exactly the same behavior.

With shrinking technology nodes and increasing complexity, logical equivalence check plays a major role in ensuring the correctness of the functionality. LEC comprises of three steps as shown below: Setup Mode, Mapping Mode and Compare Mode. Fig-1. Logical Equivalence Check flow diagram.

Equivalence checking is a portion of a larger discipline called Formal Verification. This technology uses mathematical modeling techniques to prove that two ...

Circuit Equivalence Checking Checking the equivalence of a pair of circuits − For all possible input vectors (2#input bits), the outputs of the two circuits must be equivalent − Testing all possible input-output pairs is CoNP- Hard − However, the equivalence check of circuits with “similar” structure is easy [1] − So, we must be able to identify shared

Equivalence checking takes two designs and ascertains if they have the same functionality. This is important in the design flow where the RTL design, ...

Equivalence checking. Equivalence checking, that is, determining when two (infinite-state) systems are in some semantic sense equal, is clearly a particularly relevant problem in system verification. Indeed, such questions have a long tradition in the field of (theoretical) computer science.

During the second phase of equivalence checking, the Conformal tool automatically maps key points and compares them. When the comparison is complete, it ...

17.10.2012 · Combinational and sequential equivalence checking are the two methods used nowadays. Combination Equivalence checking is done by making one-to-one mapping of flops between golden design and revised design. But Sequential equivalence checkers can verify structurally different implementations which do not have one-to-one flop mapping.

This paper proposes a novel DSS-based equivalence checking approach which can handle designs without pre-given mapping information and improve verification ...

Equivalence Checking. Given two Boolean functions, prove whether or not two they are functionally equivalent. This talk focuses specifically on the mechanics of checking the equivalence of pairs of combinational circuits. Types of Circuits.

Equivalence checking. Equivalence checking, that is, determining when two (infinite-state) systems are in some semantic sense equal, is clearly a particularly relevant problem in system verification. Indeed, such questions have a long tradition in the field of (theoretical) computer science. Since the proof by Moore [121] in 1956 of the ...

Jun 11, 2014 · on Equivalency Checking Flow – Basics. Once RTL is released, the next step is to go for synthesis to get a gate-level representation of the design. This is called synthesized netlist. Assumption is that synthesized netlist has the same functionality as the RTL. Equivalency checking comes into picture to make the assumption into a conclusion.

11.12.2019 · Logical Equivalence Check flow diagram. There are various EDA tools for performing LEC, such as Synopsys Formality and Cadence Conformal. We are considering Conformal tool as a reference for the purpose of explaining the importance of LEC. Steps for Logical Equivalence Checks.
