In iic-osic-setup.sh, the folder old-releases/ must be inserted in the download path for ngspice 36, i.e, the following works:
https://sourceforge.net/projects/ngspice/files/ng-spice-rework/old-releases/36/ngspice-36.tar.gz

I'm trying to execute the main script to install this environment for open source IC design.
I'm having this error, seems ngspice-36 is not present on the url specified in the script.

Is it a problem of my environment, or something needs to be fixed in the script?

I have installed tools and PDK using iic_osic_setup.sh script in this repo.

How to update tools and pdk to latest version installed using this script?

We're seeing issues with running Xschem with the gf180mcuC process. It doesn't seem to be working correctly. It doesn't have the models or PDK setup correctly within xschem. The $XSCHEM_LIBRARY_PATH is also not setup correctly. My teammates are also reporting simulation issues.

I start by sourcing the following .designinit file in a fresh terminal.

#!/bin/bash
export PDK=gf180mcuC
export PDKPATH=$PDK_ROOT/$PDK
export STD_CELL_LIBRARY=gf180mcu_fd_sc_mcu7t5v0

Then I start xschem, but it gives me the following incorrect pdk information in the terminal and it can't find the default process schematic as shown in the following error message pop-up.

pdk installation: using /foss/pdks
180MCU_MODELS: /foss/pdks/ngspice/models

This shows that the PDK models and the $XSCHEM_LIBRARY_PATH is not setup correctly.

Doing a diff of the xschemrc from SKY130 and gf180mcuC shows the following as the most significant difference. I also know several other differences before that which were mostly commented out values but seemed to show the gf180mcuC xschemrc is based off an older version of the xschemrc compared to SKY130.

I'm going to continue debug by updating to the latest version of the container. Is there a way to check the version number from within it?
