Arguments | -h | -help | Short help | ||
-long_help | Long help with examples and possible return values | |||
<targets> | Collection or list of output ports | |||
Description |
Removes output delay from a port. For each output port specified, removes all output delays for that port. Rise, fall, max, and min delays for each clock and reference pin on the output port are all removed. The value of the targets is either a collection or a Tcl list of wildcards used to create a collection of the appropriate type. The values used must follow standard Tcl or Timing Analyzer-extension substitution rules. See help for the use_timing_analyzer_style_escaping command for details. |

Example Usage |
# Simple output delay with the same value for min/max and rise/fall set_output_delay -clock clk 1.5 [get_ports {out1 out2}] set_output_delay -clock clk2 1.5 [get_ports {out1 out2}] set_output_delay -clock clk 1.6 [get_ports {out3 out4}] # Remove input delay on ports out1 and out4, # for all flags and reference ports and flags remove_output_delay [get_ports {out1 out4}] |
