The OpenRAM compiler has very few dependencies:
* ngspice-26 (or later) or HSpice I-2013.12-1 (or later) or CustomSim 2017 (or later)
* Python 2.7 and higher (currently excludes Python 3 and up)
* Python 3.5 and higher
* Python numpy
* a setup script for each technology
* a technology directory for each technology with the base cells

We include the tech files necessary for FreePDK and SCMOS. The SCMOS
spice models, however, are generic and should be replaced with foundry
models.
If you are using FreePDK, you should also have that set up and have the
environment variable point to the PDK.
For example, in bash, add to your .bashrc:

* compiler/base - base data structure modules
* compiler/pgates - parameterized cells (e.g. logic gates)
* compiler/modules - high-level modules (e.g. decoders, etc.)
* compiler/verify - DRC and LVS verification wrappers
* compiler/characterizer - timing characterization code
* compiler/gdsMill - GDSII reader/writer
* compiler/router - detailed router
