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.

Synopsys Formality Are you looking for?: The big problem of formal verivication. Because, such tool like Mentor Foormality or synopsys formality compares input logic for each register between RTL and gate-level netlist. If you asked Synthesis to re-balance logic, the input logic for some registers will be different.

For synopsys formalityyou can use side-file Which tool can verify functional equivalence if given two different netlist files?

My question is that if I were synopays with two designs. All written in VerilogHDL Is there any tool supported by synopsys or Cadence that can help me to verify the equivalence of these forjality desig. Hi all, i’m currently working on synopsys formality.

Afterwards the verification goes on successfully. Hi, I’m currenty trying to use synopsys Design Compiler to generate netlists for use with formality.

On compilation of a specific module, I run into this issue. Hi, is there any tool for RTL equivalence checking? Help about Formality Tutorial.

Formality –

I am planning fformality study synopsys formalitybut I don’t know where I can get the tutorial materials. I have the workshop labs for Design Compiler and PrimeTime, and I was wondering if there is such a workshop for formality. Please help me if you have the related materials. I deeply appreciate it. The post-layout netlist adds buffer for timing consideration in the path which may be output high impedance.

Therefore, formality check now thinks this is a problem because cell buffer input Z result in X output, which is different for this path not in.

How Formality do the parallel computing? Hello I try to run formality with parallel enable, I follow the instruction of fotmality document: What are the following software prices for group license?

Synopsys Formality

I want to inquire the following software pricing for group license. What’s the lowest price? Currently I’m doing verification for rtl versus netlist.

The netlist haven’t been modified. It comes right after being sythesized by synopsys Design Compiler. The main question in my mind is, why I need formslity verify the netlist.

Is it means that the tools cannot be trusted?

Synopsys formality –

In other words, there’s a possibility that the tools is. How to deal with gated clock in Synopsys Formality?

Hello, I compiled some gated clocks in my synoppsys, and when I do formal verification, the gated clock cells are in unmatch cell list, how can I tell formality about the gated clock setting? Formal verification of a clock-gated netlist with Formality.


Hi, I’ve created my own clock gating method, and I’m trying to check the logic equivalence by using synopsys formality. However, verification always fails even though I’ve checked the functional equivalence by RTL simulation. My clock gating method is as follows: Create an enable signal. RHEL37 amd64 Current time: Thu Sep 17 Forjality failed to read. Hi Guys, I meet an issue when I read.

And it takes very long time to finish the verify. Is there any good resolution? DC output file usage and the full name of these file. The relation between assertions and Formal Verification.

Hi, with formality you make an equvalence check: Netlist against RTL, based on formal methods, no assertion here.

Formal equivalence checking

The other think is called Static or Dynamic Formal Verification, and here you need to define assertions based on properties that these tools try to formally proove for the RTL design. Tools are Magellan synopsys or 0-in me. Previous 1 2 Next.
