WebOct 15, 2024 · get_lib_timing_arcs => Creates a collection of library arcs. This is very important to check that all arcs present in .lib or .db are showing here correctly for all cells. Every arc reported here is an arc with "timing_type" under timing section of that pin. So, if we find that D pi of Flop has 8 arcs for D pin in .lib file, we should see 8 ...
