@ -278,9 +278,10 @@ A variable is a bit vector that can be written by behavioral code (so
has no structural input) and propagates its output to a functor. The
general syntax of a variable is:
<label> .var "name", <msb>, <lsb>;
<label> .var/s "name", <msb>, <lsb>;
<label> .var/real "name", <msb>, <lsb>;
<label> .var "name", <msb>, <lsb>; Unsigned logic variable

The "name" is the declared base name of the original variable, for the
sake of VPI code that might access it. The variable is placed in the
