I am trying to run ngspice for a .spice generated through xschem as a test run and getting these errors
< Error: could not find include file ../../libs.ref/sky130_fd_pr/spice/sky130_fd_pr__nfet_01v8__tt.corner.spice
ERROR, library file /user/local/share/pdk/sky130A/libs.tech/ngspice/sky130.lib.spice, section definition tt not found
ERROR: fatal error in ngspice,
- Can someone please help me to understand what's happening ?
