Neurealm provided comprehensive analog mixed-signal (AMS) verification for a digital and analog microphone IP, including model updates, functional verification, and model-vs-schematic validation to ensure robust mixed-signal behavior.

Business Context

A US-based semiconductor company developing microphone and audio front-end technology needed expert AMS support to validate combined analog and digital IP blocks. Key challenges included updating behavioral models for both digital verification and AMS simulation, comparing models against schematic behavior, and ensuring thorough verification coverage before silicon sign-off.

Solutions

Neurealm updated models for use in both digital and AMS verification, executed detailed AMS functional test cases, and added targeted checks to expand verification scope. They also maintained thorough documentation of work artifacts and leveraged industry tools such as Cadence Virtuoso and Xcelium to automate verification and ensure high confidence in mixed-signal performance.
