Abstract
A timing graph representing timing information of an integrated circuit design may change after modifications are made to the integrated circuit design. The modifications change timing parameters for edges in the timing graph. The measure of these changes may be computed at a computed measure compared to a threshold. In the event the measure exceeds the threshold, the edges in the timing graph that need to change in response to the modifications are updated. Otherwise, the current edges in the timing graph are continued to be used. The threshold is set in accordance with the accuracy and efficiency requirements of an electronic design automation tool.
