DFT Acceleration

Questa One Sim DX

Questa One Sim's DFT simulation acceleration technologies, in conjunction with Tessent Silicon Lifecycle solutions, offer an all-encompassing solution that delivers the productivity and performance benefits required to sign off ATPG and MBIST pattern verification.

Why use Questa One Sim DX?

Questa One Sim DX is a simulation acceleration capability that works by leveraging Tessent Silicon Lifecycle solutions. With this combined solution, the risk of DFT sign-off becoming a bottleneck in the tape-out process is significantly reduced.

Core-level serial ATPG pattern verification

DFT teams must simulate a large combination of parallel and serial pattern sets across a number of configurations. Questa One Sim DX adopts advanced DFT-aware technologies to maximize productivity and expedite the closure process.

Top-level ATPG pattern verification

Top-level verification adds an additional verification volume to the overall effort. This includes long running serial simulations to verify test infrastructure. Questa One Sim DX provides acceleration to these simulations as well

MBIST verification

MBIST and BISR simulation sign-off can present significant challenges to project
teams. To address these challenges, the Questa One DFT Acceleration solution offers unique optimizations specifically tailored for MBIST simulations
