The following syntax runs TRACE.
trce [options] design[.ncd] [constraint[.pcf]]
Options can be any number of the TRACE options listed in the “TRACE Options” section. They do not need to be listed in any particular order. Separate multiple options with spaces.
Design[.ncd] is the name of the input physical design file. If you enter a file name with no extension, TRACE looks for an NCD file with the name you specified.
Constraint[.pcf] specifies the name of a timing physical constraints file. This file is used to define timing constraints for the design. If you do not specify a physical constraints file, TRACE looks for one with the same root name as the NCD file.
