homebrew-asic

This is a Homebrew tap for MacOS versions of various ASIC design tools, as used in the Zero to ASIC Course: https://www.zerotoasiccourse.com/

Before you start, make sure your copy of Xcode is up to date and that you've run xcode-select --install to install the Command Line Tools, then you can:

brew tap shaunplee/asic

Magic

https://github.com/RTimothyEdwards/magic

http://opencircuitdesign.com/magic/

We can build magic with OpenGL by including mesa and mesa-glu as build dependencies, but starting magic -d opengl crashes with:

X Error of failed request:  BadMatch (invalid parameter attributes)
  Major opcode of failed request:  149 (GLX)
  Minor opcode of failed request:  27 (X_GLXCreatePbuffer)
  Serial number of failed request:  7801
  Current serial number in output stream:  7801

So magic is configured --with-opengl=no.

To install magic:

brew install magic-vlsi

Tcl/Tk with X

This tap includes a copy of Tcl/Tk because the Homebrew version of tcl-tk is built without-x and Magic needs Tk built with-x.

This is split into two formulae so that Tk and Tcl both get bumped automatically.

These formulae are keg only to avoid conflicting with the Homebrew core tcl-tk.

These are installed automatically as dependencies of magic-vlsi

ngspice@36

To install ngspice from this repository:

brew install ngspice@36

Per the Zero to ASIC MPW9 install guide, the keg only ngspice@36 formula builds version 36. To add this to your path, run brew link ngspice@36 after installing.
