Automated sequential logic equivalence checking A sequential logical equivalence check (SLEC) formally verifies that two sequentially different designs are functionally equivalent. The Questa® SLEC app performs an exhaustive, formal-based analysis of two RTL designs in only a few hours — even minutes — depending on the design sizes and ...

Sequential Equivalence Checking: Sometimes, two machines are completely different at the combinational level, but should give the same outputs if given the same ...

05.11.2017 · Sequential equivalence checking Sequential equivalence checking can be used to show that a block of sequential logic produces the same output for the same inputs after it has been modified by optimization techniques such as clock gating or register re-timing. There are two main types of equivalence checks.

Questa Sequential Logic Equivalence Check (SLEC) Today's designs rely on complex industry standard interfaces that must be verified to ensure IP interoperability and system behavior. Whether a given interface is used without modification, or customized to help differentiate the end-product, integrating even mature IP can produce unexpected issues.

Sequential equivalence checking is a verification process. It takes a validated RTL model, considered to be the “specification” and compares it ...

SLEC can prove functional equivalence between two IC designs that contain differences in level of abstraction and sequential behavior. It also can verify ...

• Equivalence Checking of Retimed Circuits: Sometimes it is helpful to move logic from one side of a register to another, and this complicates the checking problem.• Sequential Equivalence Checking: Sometimes, two machines are completely different at the combinational level, but should give the same outputs if given the same inputs. The classic example is two identical state machines with different encodings for the states. Since this cannot be reduced to a combination…

Sequential logic equivalence checking (SLEC) is effective in finding bugs in new logic required to reduce dynamic power consumption, validating last minute ECOs, or verifying that design optimizations aren’t too aggressive. It is also very efficient in verifying safety mechanisms used in ISO 26262 and other fault mitigating designs.
