09/30/2021, 11:07 AMHi Harry, thanks for the answer!

09/30/2021, 11:07 AMI think I can delete the build directory after installing
Matt Venn
09/30/2021, 11:08 AMso the build was 32gb and the install was 8gb
Matt Venn
09/30/2021, 11:08 AMI'll let you know

09/30/2021, 11:08 AMI'll call that a conservative upper limit though haha

09/30/2021, 1:27 PM@Matt Venn: Take a look at the "Install" page for open_pdks. You don't need to install every submodule of skywater-pdk, and in particular for analog design, you probably don't need any digital standard cells other than sky130_fd_sc_hd (the most common) and sky130_fd_sc_hvl (in case the digital is driving 3.3V to 5.5V analog). The liberty files for the digital standard cells is what takes up all the disk space. Cleaning up or deleting the skywater-pdk repository after installing open_pdks will recover a lot of space, too, since those massive liberty files are just copied from skywater-pdk into the open_pdks space.
The most critical submodule for analog design is sky130_fd_pr.
