Experience with OVM-Based Mixed-Signal Verification of the Impedance Calibration Block for a DDR Interface
Microsemi qualified a structured approach to mixed-signal SoC verification using Questa ADMS, systematic pre-planning, and the OVM. The special requirements of interfacing to the mixed-signal DUT are encompassed by a library of driver and monitor extension elements that we call O-SRC and O-PRB. This paper talks about the verification plan, the development effort, the results achieved, and conclusions regarding the viability of these techniques for future product development at Microsemi.
