For this PDK there is only limited support (it is only in preview!) for klayout and ngspice - which are a FOSS layout tool and circuit simulator respectively. If you want to play with whats available, someone put up a colab script here: https://colab.research.google.com/gist/proppy/f63686b02309e287d4824098c728780e/ihp_pdk_playground.ipynb https://colab.research.google.com/gist/proppy/f63686b02309e2... The other two open PDKs, SKY130 and GF180MCU, have a more complete ecosystem the major tools being the opencircuitdesign suite, xschem and the OpenRoad project. If you're still interested, there's an easy to use docker container that has most of the tools in question already installed: https://github.com/iic-jku/iic-osic-tools https://github.com/iic-jku/iic-osic-tools
