By default, the time and capacitance unit values for the design are set using the values
specified in the timing libraries, when the libraries are loaded into the design. If the values in
the timing libraries differ, the software generates warning messages and sets the value to
internal default setting of 1ns for time units and 1pF for capacitance units.
To change the unit definitions being used by the software, use the setLibraryUnit
command or the Design Import - Advanced - Timing form after importing the design |
