Compare foundry measurements with model performances #605
Comments
@ra3xdh : Could you comment please, Thanks. |
I didn't fully understand what are trying to do. Could you submit a schematic? The s2p implementation for Ngspice is taken froms2spice utiliy: https://groups.io/g/LTspice/topic/75745954?p=Created,,,20,2,0,0 It may have limitations. If the s2p features for Qucs-S+Ngspice are not sufficient you may use Qucs-S+Qucsator. Qucsator has native support of touchstone files. |
Thanks. Only one curve (red) from one file is shown here. The other not. I want only show the data - not simulate with them. I can provide schematic/project, but you have to include IHP model lib. |
Hi dwarning, |
Attached are the 3 sp files as shown before in my picture. I greped them from IHP's mdl file. |

I use s-parameter files to compare foundry measurements with model performances. Question is, how can I use s-parameter from different operating points in parametric simulations only in plotting. Tried to put them in one file doesn't work (with and without an empty line between the data blocks). Using for each file an extra 2-port setup? Looks a bit elaborate.
