14.7 EDK - How do I change implementation options in EDK?

Description

How do I modify implementation options in a design?

解决方案

To change implementation options for NGDBuild, MAP, Post MAP TRACE, PAR, and Post PAR TRACE, go to the System tab in XPS. 

Under "Project Files" you will see "Implementation Options File: etc\fast_runtime.opt". 

Open this file and insert the additional option in the desired section.

By default, the implementation option settings for the MAP section look similar to the following:

Program map

-o <design>_map.ncd; # Output Mapped ncd file

-pr b; # Pack internal FF/latches into IOBs

#-fp <design>.mfp; # Floorplan file

<inputdir><design>.ngd; # Input NGD file

<inputdir><design>.pcf; # Physical constraints file

END Program map

To add a CLB packing factor of "5" during the MAP stage for example, modify the above section as follows:

Program map

-o <design>_map.ncd; # Output Mapped ncd file

-pr b; # Pack internal FF/latches into IOBs

-c 5; # CLB Packing Factor: 5 <---------------

#-fp <design>.mfp; # Floorplan file

<inputdir><design>.ngd; # Input NGD file

<inputdir><design>.pcf; # Physical constraints file

END Program map

For incremental designs, add the guide file switch "-gf system.ncd" in the PAR section of the implementations options file as described above.
