07/07/2022, 2:55 PMMy STA engine complained about identical cell-arcs in the SDF file:
(CELL
(CELLTYPE "sky130_fd_sc_hd__mux2_2")
(INSTANCE 16276)
(DELAY
(ABSOLUTE
(IOPATH A0 X (0.2280.2280.228) (0.3290.3290.329))
(IOPATH A1 X (0.2540.2700.287) (0.3480.3500.352))
(IOPATH S X (0.3030.3030.303) (0.3960.3960.396))
(IOPATH S X (0.2350.2350.235) (0.3350.3350.335)) <-------- same arc but different values
)
)
)
Is this a bug or is my interpretation wrong ?
I'm using 6c and it seems, that it only happens to muxes.
Cheers, Tobias. PS: I can't submit a testcase, sorry.
