Mixed-Signal

Verification of mixed-signal designs.

Real-number modelling and testbenches that verify digital and analogue behaviour together.

  • Real-number modelling
  • AMS testbenches
  • Digital–analogue interfaces
  • Regression

Typical cases

  • Interfaces between analogue and digital blocks are unverified.
  • Transistor-level simulation is too slow for regression.
  • Digital control and analogue behaviour must be validated together.

Scope

  • Real-number behavioural models
  • Mixed-signal testbenches
  • Digital–analogue interface verification
  • End-to-end regressions

Workflow

Mixed-signal flow
  1. Analogue model
  2. Interface
  3. Digital control
  4. End-to-end verification

Deliverables: Defined per project; for example, behavioural models, a mixed-signal testbench and regression reports.
