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}.See Also
