Formal Verification

<p>Formal Verification tools are integrated with simulation and emulation with common features such as verification management, compilers, debuggers and language support for SystemVerilog, Verilog, VHDL, UPF, and more, which enable solutions that abstract the verification process and goals from the underlying engines.</br></br></p>

Formal verification tools for verification challenges

Questa AutoCheck

A fully-automatic formal bug hunting app that finds common RTL coding errors with low effort. Requiring neither a testbench nor assertions, formally verifying designs can start as soon as RTL code is written.

Questa Connectivity Check

A fully automated solution for exhaustively verifying static and dynamic connectivity against cleartext CSV. No knowledge of formal or property specification languages is required.

Questa CoverCheck

An automatic formal solution for achieving code coverage closure faster. CoverCheck reads code coverage results from simulation via UCDB to target coverage holes.

Questa Formal Assertion Library

Formal assertion libraries improve quality and reduce schedule times by building protocol and methodology expertise into packages of reusable assertions that support popular industry-standard interfaces.

Questa Post-Silicon Debug

This app leverages formal analysis, as well as property synthesis, to rapidly give you the observability you need to root cause bugs in logic deep within the SoC, and prove fixes don’t break anything else.

Questa Property Checking

Property checking supports assertion-based formal verification to ensure designs meet specific functional requirements, exhaustively discovering any design errors that can occur without needing specific stimulus to detect the bug.

Questa Register Check

A fully automated solution for exhaustively verifying control and status register behavior against a CSV or IP-XACT register specification. No knowledge of formal or property specification languages is required.

Questa Secure Check

A fully automated solution for exhaustively verifying that only the specified paths can reach security or safety-critical storage elements. No knowledge of formal or property specification languages is needed.

Questa SLEC

SLEC performs exhaustive, formal-based analysis of two RTL inputs in only a few hours or minutes, eliminating manually creating and maintaining testbenches or rerunning massive, time and resource intensive simulation regression.

Questa X-Check

Questa X-Check analyses your RTL design, then uses formal engines under-the-hood to exhaustively identify ‘X’ propagation issues in your RTL. No knowledge of formal or property specification languages is required.
