Description |
Updates and applies SDC commands to the timing netlist. The update_timing_netlist command expands and validates generated clocks, warns about sources in the design that require clock settings, identifies and removes combinational loops, and warns about undefined input/output delays. Most Tcl commands (e.g., report_timing) automatically update the timing netlist when necessary. You can use the update_timing_netlist command explicitly to control when updating occurs, or to force a full update using the -full option. |
