Questa ADMS is the de facto industry standard for the creation and verification
of complex analog and mixed-signal designs.
Mixed-Signal Simulator for Modern Design
Questa® ADMS extends the Mentor Graphics® Questa verification
environment across the digital/analog divide. Design and verification
engineers use Questa ADMS to develop and prove complex analog and
mixed-signal designs. Questa ADMS combines five high-performance
simulation engines in one efficient tool and supports every major
electronic simulation language and exchange standard.
A Flexible Mixed-Signal Strategy
System-level verification of modern SoC designs is mandatory because of
the high cost of respins. But system-level verification presents a dilemma.
Simulating with only digital models is fast but inaccurate, and simulating
with only transistor level models is too slow. A common verification strategy
mixes and matches abstract models and detailed models, using the
appropriate simulation algorithm for each portion of the design hierarchy. A
different configuration may be used for each test point. This checkerboard
strategy optimizes performance while maintaining accuracy for decisive
criteria, but it demands flexibility along several dimensions—simulation
engine, design language, module configuration, and overall EDA flow.
