@Brady Etz @Or Dicker @Robin Tsang @Thomas Dexter @Andrew Kang @htamas @Luis Henrique Rodovalho @Lucas Daudt Franck @William Carrara Orlato: I just made a pull request to each of your projects to update to the version of the layout that I taped out. In most cases, the problems were minor and mostly due to errors that show up in the klayout DRC deck. The largest problem was caused by a DRC rule implementation that did not match SkyWater's rule deck; this was something that was discovered a few weeks ago and fixed, so the klayout deck now flags errors that it didn't previously. Mostly this involved moving unrelated metal3 shapes away from the MiM cap bottom plates. In another couple of cases, I changed the name of the top-level layout to match the project name for consistency's sake. In all cases, it's probably a good idea to run some checks and make sure I didn't break anything. The repository https://github.com/RTimothyEdwards/chipalooza_projects_1 has also been updated with some post-tapeout changes to make it LVS clean with respect to all four ground domains (vssd1, vssd2, vssa1, and vssa2), as this is the first user project design where I have attempted to keep all of the power domains independent. In the next week or so we will be linking the projects to the Efabless IP catalog.

Merge completed.
Want to add that I used a modified version of qflow’s
spi2xspice.py
in order to get xspice to work when translating a routed digital netlist to xspice. I couldn’t get the version in the current qflow distribution to work because the pull-up/down cell in sky130 is a 2-in-1 combined pull-up and pull-down cell, called
sky130_fd_sc_hd__conb_1
and is not recognized by
spi2xspice.py
. I documented it in a pull request in qflow, and made it editable by owner.

Great, thanks!
