A computer-implemented method of performing timing analysis upon a circuit design having synchronous circuit elements can include selecting a destination pin having a plurality of source pins, wherein each source pin of the plurality of source pins defines a data path to the destination pin. A slack of a selected path of the data paths to the destination pin can be determined. A timing adjustment of each of the plurality of source pins can be compared to the slack of the selected path, wherein each timing adjustment is determined using static timing analysis. A simulation node can be selectively included within the circuit design according to the comparison. The circuit design can be output.

Source specific timing checks on synchronous elements using a static timing analysis engine

A method of generating timing information for a circuit design can include determining static timing data for the circuit design and identifying a source of timing information for use in functional simulation of the circuit design. The method also can include updating the source of timing information to include at least a portion of the static timing data.

Timing annotation accuracy through the use of static timing analysis tools

A method of annotating timing information for a circuit design for performing timing analysis can include determining minimum and maximum clock path delays for registers of a circuit design and computing a difference between the maximum clock path delay and the minimum clock path delay for a destination register of the circuit design. The method further can include adjusting a register timing parameter for the destination register according to the difference and performing a timing verification on the destination register using the adjusted register timing parameter.
