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.

The netlist haven’t been modified. Maybe some additional constraints might be required.

How Formality do the parallel computing? Currently I’m doing verification for rtl versus netlist. Equivalence synopsya not to be confused with functional correctness, which must be determined by functional verification. I deeply appreciate it.

When I trying to check formal between RTL and netlist not clock gating and not scan insertion then they are no mismatch.

I’m trying to implement formality with RTL and netlist which is scan and clock gating inserted netlist. In theory, a logic synthesis tool guarantees that the first netlist is logically equivalent formaliry the RTL source code.

Formal equivalence checking – Wikipedia

Formality failed to read. Which tool can verify functional equivalence if given two different netlist synopsyz Afterwards the verification goes on successfully. Your concern is valid, but still it is not considered as a functional violation.

Synopsys Formality

This may cause simulation -synthesis. However, verification always fomrality even though I’ve checked the functional equivalence by RTL simulation. This page was last edited on 4 Septemberat How to run LEC after bottom-up syn.


I have the forjality labs for Design Compiler and PrimeTime, and Synopdys was wondering if there is such a workshop for formality. Hi Guys, I meet an issue when I read. Hi, with formality you synopsyw an equvalence check: 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.

If you asked Synthesis to re-balance logic, the input logic for some registers will be different. The big problem of formal verivication. Functional violations are caught by design verification formalityother DV tools etc. In general, there is a wide range of possible definitions of functional equivalence covering comparisons between different levels of abstraction and varying granularity of timing details. It comes right after being sythesized by synopsys Design Compiler.

Synopsys Formality Are you looking for?: My question is that if For,ality were provided with two designs. But when I insterted scan and clock gating, then they are not equality. Reading in an existing match-point file. Glad that I asked you the question. But I’m not sure what am I supposed to d. Because, such tool like Mentor FromalPro or Synopsys formality compares input logic for each register between RTL and gate-level netlist.

Formal equivalence checking

Formality Are you looking for?: These DV tools don’t care about drive strength. Hello I try to run formality with parallel enable, I follow the instruction of synopsys document: DC output file usage and the full name of these file. If you asked Synthesis to re-balance formalihy, the input logic for tormality registers will be different.


From the log-file entries below it has a lot more to go. Electronic circuit verification Formal methods.

Create an enable signal.

I’m hoping that FM will see that the points have already been ofrmality and not go off and spend time on them. Conformal LEC constant constraint. How do I fix read asynchronously in formality? Retrieved from ” https: Logic synthesis Place and route Placement Routing Register-transfer level Hardware description language High-level synthesis Formal equivalence checking Synchronous logic Asynchronous logic Finite-state machine Hierarchical state machine.

Synopsys formality –

On compilation of a specific module, I run into this issue. This description is the golden reference model that describes in detail which operations will be executed during which clock cycle and by which pieces of hardware.

Help needed formalitty Primt time!!! I am planning to study synopsys formalitybut I don’t know where I can get the tutorial materials. In other words, there’s a possibility that the tools is.
