Description | Specifies the data required times at the specified output ports relative the clock specified by the -clock option. The clock must refer to a clock name in the design. Output delays can be specified relative to the rising edge (default) or falling edge (-clock_fall) of the clock. If the output delay is specified relative to a simple generated clock (a generated clock with a single target), the clock arrival times to the generated clock are added to the data required time. Output delays can be specified relative to a pin or a port (-reference_pin) in the clock network. Clock arrival times to the reference pin or port are added to the data required time. Output delays can include clock source latency. By default the clock source latency of the related clock is added to the output delay value, but when the -source_latency_included option is specified, the clock source latency is not added because it was factored into the output delay value. The maximum output delay (-max) is used for clock setup checks or recovery checks and the minimum output delay (-min) is used for clock hold checks or removal checks. If only one of -min and -max (or neither) is specified for a given port, the same value is used for both. Separate rising (-rise) and falling (-fall) required times at the port can be specified. If only one of -rise and -fall are specified for a given port, the same value is used for both. By default, set_output_delay removes any other output delays to the port except for those with the same -clock, -clock_fall, and -reference_pin combination. Multiple output delays relative to different clocks, clock edges, or reference pins can be specified using the -add_delay option. 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. |
