How to expose X-optimism issues in ASIC and FPGA Design by Lisa Piper

Fix X-pessimism in netlists with practical techniques

Traditional approaches do not catch all unknown state sources, lack capacity for big SoCs and mask bugs. Ascent XV addresses and overcomes these issues.

Reset optimization pays big dividends before simulation

Reset is no longer simply an 'X' issue but also feeds into power optimization. Catching issues early greatly speeds verification.
