We will soon see Alliance VLSI CAD System into the Fedora Collection.
Have I mentioned Alliance VLSI CAD System was the SEYMOUR CRAY 1994 CONTEST winner, before ? Yes, this powerful opensource VLSI CAD System is up to the class.
GPL-based Alliance VLSI design system has been around for about twelve years and is in use by about 250 universities around the world. It includes simulation, synthesis, layout, design-rule checking, timing analysis and many utilities.
Alliance VLSI design system is a complete set of CAD tools for teaching VLSI design. Alliance aims at allowing universities to start and develop VLSI design activities without too much time and money investments. Each Alliance tool can operate as a standalone program as well as a part of the complete design framework.
The first time user might mixed up that which tool brought by Alliance VLSI CAD System does what. However all these are well documented in /usr/share/doc/alliance-doc-5.0/design-flow/index.html from the alliance-doc package.
I would personally recommended to spend an hour or two reading the documentations and the tutorials found at /usr/share/doc/alliance-doc-5.0/tutorials/ (available on the alliance-doc rpm)
The examples provided are simply outstanding. Do copy the /usr/share/doc/alliance-doc-5.0 directory to your home directory and try to “make” the examples. Some of them would even require one or hours for synthesis.
Below I described how I created the schematic and the layout of a 2 bit multiplexer from a VHDL description, just to familiarize myself before attacking an Operational Transconductance Amplifier (which I once did with Cadence of Mentor Graphics).
As for the automatic Schematic and Layout generation, it will surprise you. I’ve used the default technology in alliance, but one can even use his/her own technology.
All these may be simplified to one command “make”, in a Makefile.
Meanwhile, while alliance is still under review, you can try it:
* RPM (alliance i386) (alliance-doc i386)
