Opensource EDA software development, some thoughts about the EDA/Semiconductor industry and Mixed-signal integrated circuit design

Electronics: Magic VLSI and IRSIM


Magic is an open source VLSI layout tool. It is the well thought-out core algorithms which lend to magic the greatest part of its popularity. Magic is among the easiest tool to use for circuit layout.

VLSI engineers will soon have Magic in Fedora Repositories to implement their clever ideas and stay abreast of fabrication technology. It is currently being reviewed.

IRSIM is a “not to miss” tool for simulating digital circuits when using Magic . It is a “switch-level” simulator; that is, it treats transistors as ideal switches. Extracted capacitance and lumped resistance values are used to make the switch a little bit more realistic than the ideal, using the RC time constants to predict the relative timing of events.

There is currently request to review the IRSIM package at the Fedora Project :)

Next to come will be the netgen package, which is a LVS netlist comparison tool:)

    Really appreciate your work on packaging EDA tools.

    I see that both Magic and IRSIM reviews have status closed and nextrelease now.

    Does this mean that they will be available in the FC7 repos?

    cheers!
