Re: I/O Connector Definitions
a) Since I/O connectors are generally complicated, I have found it necessary
to write the necessary CDL directly (see the manual page called CDL).
b) In order to 'delay' the mapping between I/O pins and names, one could
conceivably invent a wierd 'socket', but I prefer create two macros. The first
contains a mapping between the 'wierd' connector pins (which aren't allowed to
have '0' as a pin number, whereas BELLPAC (TM) has a pin 000) and some reasonalbe
names, like 'P000', 'P001', etc. the second is a mapping between the user names
such as A<00:23>, and P023, P124, etc.
there are two problems with this: a) cdm doesn't like unused macro definitions,
and b) various programs don't like the full pathname generated, such as
NAME1/MACRO1/MACRO2.
In order to smooth over these problems, I provide to my TA's a 'standard makefile'
which they slightly modify to get things started. I also provide the .g file
that maps wierd pin numbers to P???, and the CDL for the appropriate connector.
My next news item will contain that makefile.
