Problem Title:
m1.3 ngdbuild. ERROR basut - Problem parsing '_'.


Problem Description:
keywords: ngdbuild, basut, parsing, _

Urgency: Standard

Gneral Description:  when ngdbuild tries to run edif2ngd on an edn file of an ab
el macro, it will give an error if pins (in or out) begin with an _

ERROR: basut - Problem parsing '_'. On or above line ## in file C:/active/projec
ts/blah/blah.edn.  contact the vendor of the program that produced this EDIF fil
e.


Solution 1:

remove the _ from the beginning of the pin name in the abel code and update the
macro. (in foundation).  this may require you to then go in and use the symbol e
ditor to put the pins back to match up with the rest of the schematic.



Solution 2:

In the newer ABEL compiler (beginning with Foundation 1.5), the EDIF netlist wri
ter automatically drops the leading "_" from the signal names. A warning is prod
uced in the log file (abl2edif.log) for each changed name.
