Method of HDL simulation considering hard macro core with negative setup/hold time

摘要

A method of HDL simulation is described, which may enhance HDL simulation accuracy by allowing a simulator to process a negative setup time and/or hold time. For an electronic circuit device negative setup time and/or a negative hold time, a simulation may be executed without altering the negative setup time and/or hold time to be interpreted as zero. A setup time and/or hold time may be negative relative to a particular clock cycle while being positive relative to another clock cycle. Incorporating the value of the negative setup time and/or hold time without altering its value to zero may increase the accuracy of HDL simulations.
