To invoke the NGD2EDIF translation program from the UNIX or DOS command line, enter the following.
ngd2edif [options] infile[.ngd|.nga] [outfile[.edn]]
Options can be any number of the NGD2EDIF options listed in the “NGD2EDIF Options” section. They do not need to be listed in any particular order. Separate multiple options with spaces.
Infile[.ngd|.nga] indicates the input file. If you enter a file name without an extension, NGD2EDIF looks for a file with an .nga extension and the name you specified. If you want to translate an NGD file, you must enter the .ngd extension. Without the .ngd extension NGD2EDIF does not use the NGD file as input, even if an NGA file is not present.
Outfile[.edn] is the name of the NGD2EDIF output file if you want to name it other than the root NGD design name. If you do not give an extension, .edn is added.
Note: If you are using the Viewlogic design entry tools, the outfile name must be different from the original design name, to avoid conflict with the original WIR and EDIF files. See the “Timing Simulation” chapter in the Viewlogic Interface Guide for details.
