A method and system for decreasing processing time in multi-corner static
timing analysis. In one embodiment, slack cutoff values are assigned
across a parameter process space. For example, a slack cutoff value is
assigned to each parameter in a process space by determining an estimated
maximum slack change between a starting corner and any other corner in a
corresponding process sub-space. In another embodiment, parameters are
ordered in a parameter order by decreasing magnitude of impact on
variability of timing.
