timer_add_stop

Adds the specified pin to the list of pins through which the paths will not be displayed in the timing analysis tool.

timer_add_stop -pin pin_name

Arguments

-pin pin_name

Specifies the name of the pin through which the path will not be displayed.

Supported Families

All

Description

Without stop points, you see all paths from pad to pad in the design. If you do not want to see the paths going through register clock pins, you can specify these as stop points. The path going through the specified pins will not be displayed.

Exceptions

For ProASIC3/E, ProASICPLUS, ProASIC, Axcelerator, eX, and SX-A families, Actel recommends that you use the equivalent SDC command set_false_path (SDC false path constraint).

Examples

The following example adds a stop to the pin "a<2>":

timer_add_stop -pin {a<2>}

The following example adds a stop to a clock and the clear pin "reg_q_a_0_:CLR":

timer_add_stop -pin {reg_q_a_0_:CLK}
