Chipmunk CAD (Jan 1993 Revision)
|
|
-------- --- --- ---- --------
|
|
|
|
This directory contains a revised public beta-test version of the
|
|
Caltech electronic CAD distribution. This distribution contains tools
|
|
for schematic capture, netlist creation, and analog and digital
|
|
simulation (log), IC mask layout, extraction, and DRC (wol), simple
|
|
chip compilation (wolcomp), MOSIS fabrication request generation
|
|
(mosis), netlist comparison (netcmp), data plotting (view) and
|
|
postscript graphics editing (until). These tools were used exclusively
|
|
for the design and test of all the integrated circuits described in
|
|
Carver Mead's book "Analog VLSI and Neural Systems". Until was used
|
|
as the primary tool for figure creation for the book. The directory
|
|
also contains an example of an analog VLSI chip that was designed and
|
|
fabricated with these tools, and an example of an Actel
|
|
field-programmable gate array design that was simulated and converted
|
|
to Actel format with these tools (example).
|
|
|
|
These tools were originally written for HP 200 Series ("Chipmunk")
|
|
computers, and were later ported to Unix and the X Windows System.
|
|
Many people contributed to the design and porting of these tools; we
|
|
have made an attempt to credit authors in each package, and regret any
|
|
omisions. Carver Mead provided the inspiration, initiative, and
|
|
financial support for many of the tools in this package; in several
|
|
cases (wol and wolcomp) he wrote the original prototypes as well. The
|
|
Systems Development Foundation, Hewlett Packard, and the Office of
|
|
Naval Research were the main sources of funding for these tools. These
|
|
tools are distributed under a license very similar to the GNU license;
|
|
the minor changes protect Caltech from liability. Each tar file
|
|
contains this license.
