sdf_cond missing in hd libraries
Expected Behavior
sdf_cond statements should be present on conditional arcs in Liberty.
Actual Behavior
They are present in the hs library but not the hd library.
Steps to Reproduce the Problem
Compare the hs library which has sdf_cond for mux2_1 to the hd library which does not.
Specifications
- Version: latest (per link in this repo)
- Platform: any
Did a quick survey of all the sc libraries:
🍡 grep sdf_cond sky130_fd_sc_hd/latest/cells/mux2/*.lib.json | wc -l
0
🍙 grep sdf_cond sky130_fd_sc_hdll/latest/cells/mux2/*.lib.json | wc -l

🍊 grep sdf_cond sky130_fd_sc_hs/latest/cells/mux2/*.lib.json | wc -l

🍡 grep sdf_cond sky130_fd_sc_hvl/latest/cells/mux2/*.lib.json | wc -l

🍙 grep sdf_cond sky130_fd_sc_lp/latest/cells/mux2/*.lib.json | wc -l

🍡 grep sdf_cond sky130_fd_sc_ls/latest/cells/mux2/*.lib.json | wc -l

🍙 grep sdf_cond sky130_fd_sc_ms/latest/cells/mux2/*.lib.json | wc -l

Do we know if we expect every *.lib.json for each standard cell to have at least one sdf_cond directive, or if "it depends" :)
It also seems that sdf_cond is missing for all the cells in hd:
