Hello, I have been following the installation instructions for open_pdks for the sky130 pdk from http://opencircuitdesign.com/open_pdks/index.html. My configure looks like: ./configure --prefix=$INST_PATH/cad --enable-sky130-pdk=$GIT_PDK_PATH --with-sky130-link-targets=source --with-ef-style --disable-klayout --disable-irsim --disable-openlane --disable-qflow (which seems to execute fine) and when I try to do make&make install I see a lot of information that seems to have warnings/errors. However I am not sure if that is ok or not... *However t*he "test" that makes me believe there is something wrong going on is that when I open xschem's library for sky130nm and try to run the test_nmos.sch I get the following ngspice error: Error: Could not find include file ../../libs.ref/sky130_fd_pr/spice/sky130_fd_pr__nfet_01v8__tt.corner.spice Which makes sense, because when I go to ../../libs.ref I dont have any sky130_fd_pr/ library. Does this mean that I am having problems on the open_pdks installation or somwhere else? (Apologies if this is the wrong place to ask this, I am still new to the discord channels)
