Yes. I should have pointed out the ambiguity.<br>

Also true. <br>

SCALD (Valid's software) was also ported to VAXstations (VMS with
VWS) by the late 80s. It drove development of the VWS emulator for
DECwindows.<br>
<br>
And before more nit's are mentioned: SCALD was developed under
government contract, so it became the basis of other companies, not
just Valid. But the principals behind it formed Valid - as I often
say, IP is people, not source code. And while I consider it a
schematic capture tool, in reality it's a toolchain that runs from
GED (the graphics front end) through a compiler and packager before
it becomes a wirelist that can be fed to back-end tools.<br>
<br>
DEC was one of Valid's first customers - I think the biggest - and
had a lot of input into the design. SUDS was another big
influence. The innovation in SCALD was hierarchical design.<br>
<br>
But we're way off topic here, so I'm going to stop.<br>
