Removes the previously set clock constraint.  

timer_remove_clock_exception -clock clock_name -pin pin_name -dir value

Arguments

-clock clock_name

Specifies the name of the clock from which to remove the constraint.

-pin pin_name

Specifies the name of the pin to remove.

-dir value

Specifies direction.

Supported Families

All

Exceptions

• For the ProASIC3/E, ProASICPLUS, ProASIC, Axcelerator, eX, and SX-A families, the timing analysis tool ignores the timer_remove_clock_exceptions command. To remove the clock exception, use the Set Multicycle Constraint dialog box.

Examples

This example removes a clock exception from the pin reg_q_a_10_/U0:CLK with respect to the clock clk:

timer_remove_clock_exception -clock {clk} -pin {reg_q_a_10_/U0:CLK} -dir {from}

This example removes a clock exception to the pin reg_q_a_10_/U0:E with respect to the clock clk:

timer_remove_clock_exception -clock {clk} -pin {reg_q_a_10_/U0:E} -dir {to}.
