Abstract - A probability-based method is presented for the timing delay analysis and tuning of high performance VLSI circuits. The focus is on minimizing signal path skew, while using a set of wave-pipelined circuits as a vehicle of study. A recursive variance-covariance technique that assumes Gaussian delay distributions is used to i) balance, ii) quantify and iii) fine tune the critical path skew, and iv) calibrate performance. The results on the effectiveness of the technique to analyze and fine tune the wave-pipeline combinational circuits are reported.
