13.33.140 set_input_delay

Creates an input delay on a port list by defining the arrival time of an input relative to a clock in the current scenario.

set_input_delay delay_value -clock clock_ref [–max] [–min] [–clock_fall] input_list

Arguments

delay_value

Specifies the arrival time in nanoseconds that represents the amount of time for which the signal is available at the specified input after a clock edge.

-clock clock_ref

Specifies the clock reference to which the specified input delay is related. This is a mandatory argument. If you do not specify -max or -min options, the tool assumes the maximum and minimum input delays to be equal.

-max

Specifies that delay_value refers to the longest path arriving at the specified input. If you do not specify -max or -min options, the tool assumes maximum and minimum input delays to be equal.

-min

Specifies that delay_value refers to the shortest path arriving at the specified input. If you do not specify -max or - min options, the tool assumes maximum and minimum input delays to be equal.

-clock_fall

Specifies that the delay is relative to the falling edge of the clock reference. The default is the rising edge.

input_list

Provides a list of input ports in the current design to which delay_value is assigned. If you need to specify more than one object, enclose the objects in braces ({}).
