@Stefan Schippers I currently preparing our next IIC-OSIC-TOOLS release, and I have an issue with our LVS script. Specifically, I have this fail:

Copy code

/foss/tools/bin/xschem --rcfile "$PDK_ROOT/$PDK/libs.tech/xschem/xschemrc" -n -s -q --no_x --tcl "set lvs_netlist 1; set lvs_ignore 1; set netlist_dir $PWD" inv.sch -N inv.test.spice
open_pdks installation: using /foss/pdks
SKYWATER_MODELS: /foss/pdks/sky130A/libs.tech/ngspice
SKYWATER_STDCELLS: /foss/pdks/sky130A/libs.ref/sky130_fd_sc_hd/spice
setup_tcp_bespice: success : listening to TCP port: 2022
tcleval(): evaluation of script: netlist {/foss/designs/example/ana/.inv_584} noshow {inv.test.spice} failed
         : can't read "simulate_bg": no such variable

Any idea what is going wrong?

@Stefan Schippers this is produced with

-d 1

Copy code

global_spice_netlist(): starting awk on netlist!
tcleval(): evaluation of script: netlist {/foss/designs/example/ana/.inv_914} noshow {inv.test.spice} failed
         : can't read "simulate_bg": no such variable

@Harald Pretl The bug is now fixed upstream.. For a quick workaround remove the

--no_x

from the xschem command line. The

$simulate_bg

changes some menu button colors after netlisting, but this can not be done if xschem is started with no X (no windows, no GUI). Thank you for pointing this out.

Since I am in the middle of preparing the new release I will just upgrade the

xschem

version… thanks for the quick fix! 🙂
