#37 netgen only ignores cells in libraries with 2 characters: ie, hd, hs, etc. Not hdll, hvl, etc. Issue opened by d-m-bailey Currently,

# Digital cells (ignore decap, fill, and tap cells)
# Make a separate list for each supported library
#---------------------------------------------------------------
# e.g., ignore class "-circuit2 sky130_fc_sc_hd_decap_3"
#---------------------------------------------------------------

foreach cell $cells1 {
    if {[regexp {sky130_fd_sc_\w\w__decap_[[:digit:]]+} $cell match]} {
        ignore class "-circuit1 $cell"
    }
    if {[regexp {sky130_fd_sc_\w\w__fill_[[:digit:]]+} $cell match]} {
        ignore class "-circuit1 $cell"
    }
}
foreach cell $cells2 {
    if {[regexp {sky130_fd_sc_\w\w__decap_[[:digit:]]+} $cell match]} {
        ignore class "-circuit2 $cell"
    }
    if {[regexp {sky130_fd_sc_\w\w__fill_[[:digit:]]+} $cell match]} {
        ignore class "-circuit2 $cell"
    }
}

Maybe,

sky130_fd_sc_[^_]*__fill_

would work better. RTimothyEdwards/open_pdks
