Discrepancy in pin order of stdcell spice models vs. xschem symbols #61

Open bmurmann opened 1 month ago

bmurmann commented 1 month ago

I am not sure of this was brought up here already. The spice pin order between these two stdcell representations do not match up:

libs.tech/xschem/sg13g2_stdcells libs.ref/sg13g2_stdcell/spice/sg13g2_stdcell.spice

The spice file pins are in alphabetical order, but the xschem pins are not.

The following sed applied to the xschem symbols fixes the problem (courtesy Mitch Bailey): sed -i .bak \ -e 's/@VGND @VNB @VPB @VPWR/@VDD @VSS/' \ -e 's/VGND=VGND VNB=VNB VPB=VPB VPWR=VPWR/VDD=VDD VSS=VSS/' \ -e 's/VGND VNB VPB VPWR/VDD VSS/' \ -e 's/@VDD @VSS @@Q @@Q_N/@@Q @@Q_N @VDD @VSS/' \ -e 's/(@@RESET.)@@Q @@Q_N /@@Q @@Q_N \1/' .sym

Dear @bmurmann thank you for notification and the sed code snippet. Please checkout the recent PR #63 where the standard cells symbols were updated.
