  • Method and computer program for static timing analysis with delay de-rating and clock conservatism reduction
    Patent number: 7480881
    Abstract: A method and computer program for static timing analysis includes receiving as input minimum and maximum stage delays for two corners of an integrated circuit design. A path slack for a setup timing check is calculated from the minimum and maximum stage delays as a function of net clock cycle interval T_clk, launch path delay T_LP, capture path delay T_CP, data path delay T_DP, and a first delay de-rating factor Y1. A path slack for a hold timing check is calculated from the minimum and maximum stage delays as a function of the launch path delay T_LP, the capture path delay T_CP, the data path delay T_DP, and a second delay de-rating factor Y2. The path slack calculated for the setup timing check and for the hold timing check is generated as output.
