Randomisation in the Real world

Randomisation in the Real world
Constrained-random verification (CRV) is a well-established and successful methodology for digital designs and UVM has become the primary means to achieve this. The functional complexity in mixed-signal designs is increasing exponentially. Even a simple Power Management Unit can have hundreds or thousands of control bits and many modes of operation. To achieve good functional coverage it is important to adopt a CRV approach for mixed-signal designs. This approach can help us manage a large verification space, including: checking analogue performance under a large set of programmable configurations; digital control system interaction with analogue circuits; covering unexpected corner cases in A/D interaction. This presentation shows some of the ways in which Renesas has applied UVM to mixed-signal designs and some of the benefits we gained by doing so.
