#683 flow.tcl no longer handles multiple simulation libraries. New issue created by d-m-bailey Description An attempt to copy

LIB_SYNTH_COMPLETE

as a file fails because it may be a list of files. In

scripts/tcl_commands/all.tcl

# trim resizer library
        if { ! [info exists ::env(LIB_RESIZER_OPT) ] } {
            set ::env(LIB_RESIZER_OPT) $::env(TMP_DIR)/resizer.lib
            file copy -force $::env(LIB_SYNTH_COMPLETE) $::env(LIB_RESIZER_OPT)       <- Attempt to copy list of files
            if { $::env(STD_CELL_LIBRARY_OPT) != $::env(STD_CELL_LIBRARY) } {
                set opt_lib $::env(TMP_DIR)/resizer_optlib.lib
                file copy -force $::env(LIB_SYNTH_OPT) $opt_lib
                lappend $::env(LIB_RESIZER_OPT) $::env(LIB_SYNTH_OPT)
            }
        }

For reference, here is how

SYNTH_LIB_COMPLETE

is handled in

scripts/tcl_commands/synthesis.tcl

set ::env(LIB_SYNTH_COMPLETE_NO_PG) [list]
        foreach lib $::env(LIB_SYNTH_COMPLETE) {
                set fbasename [file rootname [file tail $lib]]
                convert_pg_pins $lib $::env(TMP_DIR)/$fbasename.no_pg.lib
                lappend ::env(LIB_SYNTH_COMPLETE_NO_PG) $::env(TMP_DIR)/$fbasename.no_pg.lib
        }

    Fix typo in python exit call (#677)
    
    In commit 4e158a77ef7a ("Quit on timing violations at the typical
    corner (#659)"), os.EX_DATA should have been os.EX_DATAERR.

Reproduction Material Any design with the

sky130_fd_sc_hvl

libraries will probably give the same error. Expected behavior Should be able to handle multiple simulation libraries, I assume. Logs From the slack conversation.
