Abstract:
1. A system for identifying latches in physical designs with unbalanced slack, comprising: a placement driven synthesis (PDS) module configured to receive a netlist describing a logical design having a plurality of latches therein, the PDS module performs a placement of the logical design to obtain a physical design; a PDS graphical system in communication with the PDS module, the PDS graphical system measures a slack difference of each of the plurality of latches and selects a color for each of the plurality of latches based on the slack difference correspondingly measured for each of the plurality of latches; and a graphics application program interface (API) module in communication with the PDS graphical system, the graphics API module generates a graphical image identifying each one of the plurality of latches with slack difference in color, the color selected for each one of the plurality of latches with slack difference being indicative of the severity of the slack difference.
