Looking at /home/jcyr/pdks/sky130A/libs.ref/sky130_fd_sc_hd/lib/sky130_fd_sc_hd__ff_n40C_1v95.lib, we have:

operating_conditions ("ff_n40C_1v95") {

Moving default_operating_conditions like such, and doing the same for /home/jcyr/pdks/sky130A/libs.ref/sky130_fd_sc_hd/lib/sky130_fd_sc_hd__ss_100C_1v60.lib:

Fixes the two warnings, but the missing /openLANE_flow/openlane/designs/myproject/runs/25-11_06-35/results/synthesis/*myproject.synthesis_optimized.v* error remains a show stopper. Any ideas why it isn't being created? efabless/openlane
