set_disable_timing (::quartus::sdc)

The following table displays information for the set_disable_timing Tcl command:

Tcl Package and Version	Belongs to ::quartus::sdc 1.5
Syntax	`set_disable_timing [-h \| -help] [-long_help]` `[-from` <name> `]` `[-to` <name> `]` <cells>
Arguments	`-h \| -help`		Short help
	`-long_help`		Long help with examples and possible return values
	`-from` <name>		Valid source pin suffix
	`-to` <name>		Valid destination pin suffix
	<cells>		List of cells
Description	This exception is rarely necessary. Its intended use is to cut combinational loops. Aside from that it should likely only be used when advised by Intel Premier Support. Disables a timing edge (arc) from inside a given cell or cells. Disabling a timing edge prevents timing analysis through that edge. If either -from or -to (or both) are unspecified, the missing value or values are replaced by a "*" character. The values of the -from and -to are valid pin suffixes. The values used must follow standard Tcl or Timing Analyzer-extension substitution rules. See the help for use_timing_analyzer_style_escaping for details.
Example Usage	set_disable_timing -from datain -to combout A\|B set_disable_timing -from carryin *
Return Value	Code Name	Code	String Return
	TCL_OK	0	INFO: Operation successful
	TCL_ERROR	1	ERROR: Timing netlist does not exist. Use create_timing_netlist to create a timing netlist.
