CDM fix
CDM fix description follows ...
If you use the macro feature of ucds, you have probably encountered an
annoying "feature" concerning unused parameters. If, for example, you
have a general purpose macro with 3 output pins two of which are used
in one occurrence and the third which is used in another occurrence,
you will get an error message such as the following:
% NAME(TYPE) XXX unused parameter
Now it also generates a line in the output (stdout) and resultant .wx
like this:
o XXX; XXX
Which causes the place program to go to never-never land.
Don't dispair! A "solution" (patch) can be achieved with the following
program.
Oh, yea. This program also takes I/O connector names and strips their
name back to the base name. This is necessary since the
board descriptions have only the base name and will not be recognized
otherwise. For example, if within macro1 you connect to I/O connector
TNconn pin 1, then the name for that TNconn in the .wx file will be
stripped from macro1/TNconn down to TNconn (as it appears in the .wb file).
########################################################################
# THIS PROGRAM RUNS CDM AND STRIPS ERRONEOUS OUTPUT FROM THE RESULT FILE
# The standard output is sent to .wx
# The error output goes to CDMERR
# Error output less "unused parameter" messages is saved in stderr
#
# Warnings, rather than error messages, are used for unused pins
# on macros.
#
# I/O connector names are stripped back to the base names to
# correspond to the names that will appear in the
# board (.wb) description.
#
# Lines with semi-colons are removed, since these result from
# occurrences of unused parameters.
echo ":cdm $* 2>CDMERR >.wx"
cdm $* 2>CDMERR >.wx
