Question

< U017H530WC9> libraries are broken All devices have been simulated and the simulation netlists are in the repository under sky130 fd pr lt cell gt tests There is an assortment of devices that require more than the top level `sky130 lib spice` file in the netlist On the one hand it would be nice to have a single file that includes everything necessary to find every device On the other hand it takes ngspice something like a full minute to read all the files oddly it appears to read all of the files even the ones that aren t in the if conditional block for the specified corner so there s a conflicting wish for a leaner way to include a smaller set of devices

Tim Edwards · Answer

< jrsharp> You should be using lib and not inc there The sky130 lib spice is a lib type file It takes an extra argument the corner e g tt and uses that to select a specific section out of the file If you don t use lib it will try to read all of the files for all of the corners which is not good

< Tim Edwards> I see thanks for that slightly smiling face it was a spice noob error
