Vl-occform-mkports

Helper function for creating lists of port declarations.

Signature

(vl-occform-mkports prefix i n &key dir width (loc '*vl-fakeloc*)) 
  → 
(mv exprs ports portdecls vardecls)

Arguments

prefix — name prefix for each port.
    Guard (stringp prefix).

i — starting index, inclusive!.
    Guard (natp i).

n — ending index, non-inclusive!.
    Guard (natp n).

dir — direction of each port.
    Guard (vl-direction-p dir).

width — width of each port.
    Guard (posp width).

loc — Guard (vl-location-p loc).

Returns

exprs — Type (vl-exprlist-p exprs).

ports — Type (vl-portlist-p ports).

portdecls — Type (vl-portdecllist-p portdecls).

vardecls — Type (vl-vardecllist-p vardecls).
