An original solution based on Level 1 model via geometric programming is obtained first. Then simulate the original circuit by Hspice and acquire important parameters of all CMOS transistors from the output list file. These parameters are used in adjusting software to search the adjusting factors and achieve a new solution near the previous one. Simulating and geometric programming iteratively until the objective of optimization keeps stable. A simulation example proves the algorithm is effective in shortchannel techniques.
