Hi, John,
I came across this quote in your DAC'99 Trip Report on your web site talking
about Synopsys TetraMax ATPG.
We've recently run TetraMax on a complex 3 million gate design that is
already in production. The original set of vectors (30 million) had been
generated using Synopsys TestGenXP (formerly Sunrise). We used to run
TestGenXP ATPG distributed over a dozen hosts, resulting in about 3 days CPU
time (more than one month on single CPU!!!). We did the same with TetraMax
and the results have been quite astonishing: 4 days on a single CPU only,
producing *half* the vectors w/ a negligible coverage reduction (about 1%).
We're now working on correlating the vectors on ATE versus the original set,
but certainly this preliminary result is very satisfactory.
