Syntax remove_input_delay [-h | -help] [-long_help] [-blackbox]
 
<targets>
Arguments -h | -help Short help
-long_help Long help with examples and possible return values
-blackbox Removes an input delay that was assigned to a partition boundary port.
<targets> Collection or list of input ports
Description
Removes input delay from a port. For each input port specified,
removes all input delays for that port. This means that rise, fall,
max, and min delays for each clock and reference pin on the input port
are all removed.

The value of the targets is either a collection or a Tcl list of
wildcards used to create a collection of the appropriate type.  The
values used must follow standard Tcl or Timing Analyzer-extension
substitution rules.  See help for the use_timing_analyzer_style_escaping
command for details.
Example Usage
# Simple input delay with the same value for min/max and rise/fall
set_input_delay -clock clk 1.5 [get_ports {in1 in2}]
set_input_delay -clock clk2 1.5 [get_ports {in1 in2}]
set_input_delay -clock clk 1.6 [get_ports {in3 in4}]

# Remove input delay on ports in1 and in4,
# for all flags and reference ports and flags
remove_input_delay [get_ports {in1 in4}]
