Monte Carlo Timing Analysis

Estimate the yield of a timing path under process variation by Monte Carlo sampling the gate delays and counting how often setup time is met.

Constraints

• Path is a list of nominal gate delays with a percentage sigma.
• Delays are lognormally distributed so they cannot go negative.
• Report yield as the fraction of runs meeting the clock period.
• Also report the mean and the 3-sigma delay.
• Use at least 10000 trials.
• Seed the generator so results are reproducible.
