| Subject: | Netlist module converts "supply" statements to "wire" |
"supply0" and "supply1" statements frequently appear in netlists to
indicate nets that are connected to power supplies. Presently an input
such as:
supply1 Vdd;
will be silently converted to:
wire Vdd;
on output, resulting in an undriven net.
A patch is attached.
Regards,
Jeff Trull
