REDUCING RUNTIME AND MEMORY REQUIREMENTS OF STATIC TIMING ANALYSIS

摘要

Systems and methods for performing static timing analysis during IC design. A method is provided that includes obtaining canonical input data. The method further includes calculating at least one input condition identifier based on the canonical input data. The method further includes comparing the at least one input condition identifier to a table of values. The method further includes that when a match exists between the at least one input condition identifier and at least one value within the table of values, retrieving previously calculated timing data associated with the at least one value, and applying the previously calculated timing data in a timing model for a design under timing analysis.

1. A method comprising:
obtaining canonical input data; calculating at least one input condition identifier based on the canonical input data; comparing the at least one input condition identifier to a table of values; and when a match exists between the at least one input condition identifier and at least one value within the table of values, retrieving previously calculated timing data associated with the at least one value, and applying the previously calculated timing data in a timing model for a design under timing analysis; and when a match does not exist between the at least one input condition identifier and the at least one value within the table of values, calculating timing data for the at least one input condition identifier, saving the at least one input condition identifier as a value in the table of values, and applying the calculated timing data for the at least one input condition identifier in the timing model for the design under timing analysis, wherein at least the comparing is performed using a processor.
