Conformal and Formality are both formal equivalence tools – they check that two circuit descriptions are functionally the same. They both have. 2, Synopsys Inc. introduced Formality, the industry’s first formal verification tool for equivalency checking of million-gate, system-on-a-chip (SOC) designs. This document contains a brief introduction to Synopsys Design Analyzer, Sysnopsys Formality, and. Cadence Conformal tools. You would.

When I trying to check formal between RTL and netlist not clock gating and not scan insertion then they are no mismatch. What can be possible reasons for that? Fomality do I fix read asynchronously in formality? Variable is are being read asyncronously. Hi, is there any tool for RTL equivalence checking? I have the workshop labs for Design Compiler and PrimeTime, and I was wondering if there is such a workshop for formality.

The job is on a 64bit machine using. Please help me formwlity you have the related materials. Formal verification of a clock-gated netlist with Formality.

Synopsys formality –

I’m hoping that FM will see that the points have already been matched and not go off and spend time on them. How to deal with gated clock in Synopsys Formality? Create an enable signal. My question is that if I were provided with two designs. If you asked Synthesis to re-balance logic, the input logic for some registers will be different.


I want to inquire the following software pricing for group license. If you are using DC to synthesize, it is preferred to use formality and not Conformal for formal verification. This page was last edited on 4 Septemberat This process is called formal equivalence checking and is a problem that is studied under the broader area of formal verification.

A formal equivalence check can be performed between any two representations of a design: Digital signal Boolean algebra Logic synthesis Logic in computer formaality Computer architecture Digital signal Digital signal processing Circuit minimization Switching circuit theory.

Throughout every step of a very complex, multi-step procedure, the original functionality and the behavior described by the original code must be maintained.

From the log-file entries below it has a lot more to go. From Wikipedia, the free encyclopedia.

How can I formality check what inserted scan and clock gating? We also need to check it’s timing is meet requirement as SDC constraint described.

Synopsys Formality

This may cause simulation -synthesis. And it takes very synopsya time to finish the verify. Formal equivalence checking process is a part of electronic design automation EDAcommonly used during the development of digital integrated circuitsto formally prove that two representations of a circuit design exhibit exactly the same behavior.


Conformal LEC constant constraint. Previous 1 2 3 4 5 6 7 Next. However, the problem with this is that the quality of the check is only formqlity good as the quality of the test cases. But when I insterted scan and clock gating, then they are not equality. What’s the lowest price? The big problem of formal verivication. Once the logic designers, by simulations and other verification methods, have verified register transfer description, the design is usually converted into a netlist by a logic synthesis tool.

Electronic circuit verification Formal methods.

I am planning to study synopsys formalitybut I don’t know where I can get the tutorial materials. Historically, one way to check the equivalence was to re-simulate, using the final netlist, the test cases that were developed for verifying the correctness of the RTL.
