How do we map special symbols like power and ground in system capture?

Smith ecad

I have multiple power symbols which I want to use in my design but in the special symbols section I could only see cadence symbols.

How do I add my symbols to use it in my schematic.

    In Allegro System Capture, you can control most of the customizations through the CPM directives specified at the site/project level. If you need to configure the "Special Symbols" section to add/delete components like power symbols, flag bodies, and so on, the following steps should help:

    1. Navigate to your $CDS_SITE/cdssetup/projmgr/ and open the site.cpm file in a text editor. 

      Note: If you do not have a site-level customization, you can do the changes at the project level by modifying the project CPM file.
    2. In the site.cpm file, locate the section START_CANVAS/END_CANVAS and add the following directive:

      POWER_SYMBOLS '<NAME>!<VOLTAGE>:<LIBRARY>:<SYM NAME>:<SYM VERSION>'

      Example: POWER_SYMBOLS '+1_5V!1.5V:standard:p1_5v:sym_1'
       
    3. Save the site.cpm file and launch Allegro System Capture.
    4. In the "Special Symbols" section, you should now see the configured power symbol.
