1. Verification Reuse Simple (relatively) reuse: Difficult reuse
From one project to the next:
BFMs, Monitors, Coverage on protocols
From block to full-chip
Coverage, Assertions, Checks
Difficult reuse
Tests, Environments, Sequences
From block to full-chip:
Tests, Drivers
What helps reuse work?
Methodology (eRM)
Coding conventions
design for reuse
Code reviews
Experienced engineers
Setting managements’ expectations correctly
