* In run_non_interactive_mode make -no_lvs -no_drc -no_antennacheck into flags These don't need an argument and the code was already looking in flags_map. Signed-off-by: Matt Liberty <mliberty@eng.ucsd.edu> * in ioplacer.tcl use proper commands rather than internals Signed-off-by: Matt Liberty <mliberty@eng.ucsd.edu> * Add DFF_LIB_SYNTH optional variable for dfflibmap dfflibmap can only take a single liberty file. If LIB_SYNTH has multiple files then DFF_LIB_SYNTH is the one with all the sequential elements. If unset then LIB_SYNTH will be used for backward compatability. Needed for asap7 which uses multiple liberty files. Signed-off-by: Matt Liberty <mliberty@eng.ucsd.edu> * Handle multiple liberty files and empty CELL_PAD_EXCLUDE for asap7x Signed-off-by: Matt Liberty <mliberty@eng.ucsd.edu> * Thanks, GitHub Actions Team Co-authored-by: Donn <me@donn.website>
