This is crashing because when the code is looking for the diode specified, it returns a list of three diode ports (from the sta::get_lib_pins function). I see that the diode cell sky130_fd_sc_hd__diode_2 is defined in three different liberty files.
Are you reading all of them in this run?
@donn @maliberty Also, is it valid to have multiple definitions of the same cell in different liberty files and read them in the same run? If so, I think I have a fix for this issue, but I'm not sure if it's ok to have this scenario.
You could have multiple liberty files for different corners however there should only be one LEF.
foreach lib $::env(LIB_SLOWEST) {
read_liberty -corner ss $lib
}
foreach lib $typ {
read_liberty -corner tt $lib
}
foreach lib $::env(LIB_FASTEST) {
read_liberty -corner ff $lib
}
is legal
