Observations
• Project A re-ran post-silicon tests in simulation
•
•
environment to confirm that full functional and code
coverage was achieved.
Project B spent 10 man years developing random tests
for the ADS environment.
In project C people are not prepared to listen about CDV
verification when they spend all their effort in developing
a direct regression suite that needs to be re-usable on
ADS.

Definition
•Taking an existing subset of the pre-silicon
(simulation) verification environment and run it
within the post silicon environment.
•Includes
• Direct tests written in c/asm.
• Random Stimulus generation
• Data Checking/Post processing.
• Coverage.
• Interface generators.
• FPGA/Emulators.
