How to get a list of Electrical Netclass groups?

aCraig

Does anyone know how to get a list of electrical netclasses? I've tried:

   groups = axlSelectByProperty("group" "ELECTRICAL_CONSTRAINT_SET")

but this only returns "BUS" and "DIFF_PAIR". I've also tried: 

   groups = setof(g axlDBGetDesign()->groups g->type == "NETCLASS")

this returns all the physical, spacing and electrical netclasses, but for some reason I can't test any of the physical, spacing or electrical properties, such as car(groups)->electrical. This give a *WARNING* (dbidGetProp): Attribute electrical not supported for the element, group.

TIA

  • fxf,

    The first line works fine. I never saw "netclass" documented as a design attribute. Guess I should have looked at axlDBGetDesign.

    The second line fails, just like I stated above in my original post. You can't test for "item->electrical". bug??

  •  It works for me using 16.2. The message ( "Attribute electrical not supported for the element, group") indicates that you have enabled axlDebug() and are accessing this attribute on a group that is not a netcalsss group. You should disable axlDebug 

    nc = axlDBGetDesign()->netclass
    enc = setof(item nc item->electrical)
