update_timing_netlist
Usage
update_timing_netlist [-full]
Options
-full: Forces creation of an updated timing netlist to ensure correctness
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.
Example
project_open top
create_timing_netlist
read_sdc
update_timing_netlist
report_timing -to_clock clk1
report_timing -to_clock clk2
delete_timing_netlist
project_close
