I meant that I am *taking* a digital logic design class at school, and
thought the software might be useful in chip/board layout.

There are programs to do this under windows, but CDA would give me an
excuse to play with plan9 under the guise of doing schoolwork ;-)

When I was taking a digital logic class a few years
ago I reread the CDA documentation, though not the
actual code.  As Rob said, it's very out-of-date. 
It's almost certainly not worth the work of getting
it released.

Awawawa, I happened to make mistake.
I wanted to push 'Del" button, but 'Post' real...
Sorry about that.

Probably, if you say why "that" is not included in the present distribution,
although it was included before, you are makeing pressure to the
developpers of Plan 9.   At least, they may feel so.

This is my proposal to them open.☺

You don't need to feel pressure, if it concerns with applications.
It is applications what make OS usable or attractive to ordinally
people like me.   However, all human has their own limits in given
abilities.

Someone at the labs will have to figure out if the software can be sprung.
It has not been released under the Plan 9 license.

I doubt the value of the software, however.  It is to modern circuit design
tools what bare, unmacroed troff is to Word or Frame.  Teaching a course
with it would be unwise, in my opinion.  Its interface is too old-fashioned
and esoteric even in that context, and it was developed in a very different
age of hardware, with lots of TTL DIPs and no ASICs, some PALs but no
FPGAs, wire wrap but no PCBs.  Also, maintaining the data that describes
the parts was a pain, and you'd have at least a decade of catch-up to do
before even starting.

There are some nice pieces of software in their, most notably the tool
for Quine-McClusky reduction, but it would be a lot of work to connect
that to modern components and there must be other such tools available
today.

Seriously, I doubt you'd find it a wise place to start.

The "historic" papers page on the wiki mention "Circuit Design Aids for
Plan 9" from the first edition. Is anything left from that project?
I am starting a digital logic design class at school and thought this
might be helpful to me.
