Abstract :
A new algorithm used in a CMOS circuit speed optimization tool, SLOP version 2, is presented. In this algorithm, no user direction is involved except the circuit description. Macromodeling and verification techniques are used to improve the speed and the completeness. The delay calculation is improved by considering the node coupling effect. In most cases, the delay errors are less than ±15% compared with SPICE simulation. The CPU time is substantially reduced, especially for pipelined circuits
