I'm curious about what sort of software might have been used during the 1980s on
VAX-11/7xx series machines to support design and/or production of electronic hardware.
If there are any dusty old archived copies of such software that I might be able to
experiment with on my VAX-11/730 (after I get it running, that is), that would be pretty
exciting.

That's a Verilog simulator, isn't it?

I wonder what sort of software DEC used in their hardware design and production back in
the early to mid 1980s?

Well, in the 1980s, the hot thing was dedicated hardware for design
simulation. ZyCAD comes to mind as one such outfit...

Yes.
VAX machines were sometimes rebadged or hidden inside other vendors
CAD systems. I still have a VAX-11/751 in an Applicon cabinet that I
am trying to get rid of.
Intergraph also used VAX machines as servers, with weird add-ons for
dealing with graphical entities.

Cool pic, thanks for posting that. It's so hard to find any information
(pictures, documentation) about old Intergraph equipment. It seems as if
the company over the years had worked very hard to ensure they were more or
less redacted from history. The only Intergraph you can see, is that which
exists today :(
(OT: I used to have a couple of their Series 2400 machines, with Clipper
chips in them; strange boxes! Never had all the resources to make one run.
I do wish I still had at least that oddball Clipper CPU around as an
artifact)
Best,

I don't think there's any specific desire on their part to be excised
from history, it's just another example of one of
those companies
whose heyday was in the pre-internet era and when the internet
became
dominant, the company was focused entirely on it's software business
and didn't do hardware anymore. Intergraph was always big in the
government arena for things like GIS and large-scale CAD (think
aircraft carriers instead of engine blocks).

I remember PDP-15 systems being used for PCB CAD around 1978. And in late 1980 my boss,
lead DECnet/E designer, left that group a few months after hiring me as his junior
developer, to join a new IC CAD group being put together at DEC Hudson. I also remember
hearing of a thing called DECsim which sounded like a system (as opposed to IC) simulation
tool.
In the late 1980s, the Western Research Lab did some very interesting CAD work in a
project to build a single chip processor (MIPS-like, or Alpha-like?) in ECL technology.
That was unheard of ? no one was doing VLSI ECL. They developed their own tools that made
this possible, including being able to define a design in a process-independent fashion so
that they could switch from one fab to another ? changing layout constraint rules ?
easily. In the end, I don?t think the chip was built, but it produced some interesting
offshoots such as early designs for heat sinks and chip test fixtures that would work with
chips running at well over 100 watts.
One thing I remember about that CAD suite is that it let you define subsystems in a number
of ways ? geometry, transistor level, logic gate level, and C code. For example, you
could wrap a flip-flop in ?for (i = 0; i < 64; i++)? to define a 64-bit register. And
they could do behavioral models, power requirement analysis, and chip layout from a single
set of definitions.
I assume at some point there must have been a move to industry tools as opposed to
internally developed ones, but I don?t know when, or to what extent, that happened.

SPICE is still useful software! I remember using it occasionally when doing
my circuits homework back in engineering school (this'll probably get a lot
of groans...) ca. 2002-2003. Much easier for me to figure out than
CADENCE!! :)

Well, regular SPICE is also open source, but development
pretty much ended at 3f5. Ngspice is a current-development
continuation of 3f5, but it probably won't run on an 11/750
very well.

A bunch of DEC technical reports were added to bitsavers. I think I
remember seeing this project mentioned in some of the titles:

I was in DEC h/w engineering from '75 thru '82.
Most of the systems designed and produced prior to about 1980 or so had manually
drawn schematics, by draftsmen on vellum.
Most of these are pretty obvious to identify by looking at the copies of the
maintenance print sets.
The netlists for these boards were manually transcribed to text to be
transferred to the PCB layout systems.
PCB layout was done on standalone PDP-15 systems with an attached graphics
display, button console, etc, using DEC custom software.
Starting in '79 or so DEC engineering imported the 'SUDS' system from
Stanford,
which allowed for graphical schematic design.
Here is a reference:
http://bitsavers.trailing-edge.com/pdf/dec/engineering/The_Stanford_Univers…
SUDS itself ran on DEC-10s. Users sat at dedicated 11/34+VS60 graphics terminals.
Typically a DEC engineering site might have two to three SUDS stations for use
by engineers (or for lab techs entering schematics for old school engineers who
did not know how to use these new fangled computer devices).
SUDS terminals were a sought after resource. I don't know how many overnights I
spent at a SUDS terminal back then, but it was more than a few.
The PDP-11/44 and 11/24 were designs done on SUDS, as was the VAX-11/730.
You can recognize the SUDS schematic pages as the might have the 'default'
drawn-by signature of 'S. Foonly' in the title box.
They will also have the file name of the page in the title box, something like:
[160,1257]XXXX.DRW
PCB layout was still done using the legacy PDP-15 systems, but the netlist could
be exported from SUDS.
I don't know if SUDS was ever ported to a VAX host (it would have been a lot of
work, as I believe it was written in Macro-10).
At least while I was around in the early 80s one of the key reasons to keep a
KL-10 at each DEC engineering site was as a SUDS host.
How long SUDS remained in use after '82 (when I left) I can't say.

I think DEC probably started using it in LCG before 1975, since the KL10
schematics are drawn in SUDS. However, it may well have taken a few years
to be adopted by other parts of DEC.

When I began with my current company in 1989, I was doing PCB layout and
schematic capture for MIL qualified avionics.
For schematic capture, we had a trio of Valid Scaldstation minis that
served several green screen graphics terminals each. Each terminal was a
~19" tube attached to a dedicated table with a built in digitizer. The
SCALD software allowed the engineers to run circuit simulations and the
draftsman to generate releasable drawings and generate a netlist to send to
board layout.
For the board layout we used the Scicards software on a 11/780 running
VMS. Like the Valid machines, the Scicards had its own dedicated graphics
terminal with integrated digitizer. The main difference was that the
Scicards terminal was color and we only had a single seat.
As far as usability goes, the Valid machines were very nice to use and were
relatively easy to get the desired results with. On the other hand, the
Scicards software is memorable for how annoying it was to use. I vividly
recall creating long lists of guessed X-Y coordinate moves to try to get
the text and symbols to be where you wanted them, only to see them land in
the wrong spot. Repeat.
By the way, all of the equipment mentioned was transferred into the
collector community when we moved back in 2002. I don't recall who has
them, but there are (were?) Scicards and Valid terminals out there.
