#554 multi vt support failing during run_magic_spice_export New issue created by vijayank88 Description I am trying to use sky130_fd_sc_hdll std cell library during synthesis and sky130_fd_sc_hd cell library during optimization by setting below variable in config.tcl. #multi vt checking set ::env(STD_CELL_LIBRARY) "sky130_fd_sc_hdll" set ::env(STD_CELL_LIBRARY_OPT) "sky130_fd_sc_hd" But got failed with error.
