Help with the script
« on: November 28, 2018, 09:57:13 am »
Hello. I kindly ask for your help in making script - it will import DC op points (voltages) from LTspice and put'em as a note to specified nets in Altium schematics. Below there is an example of the output file which i'm about to import from LTspice.
.nodeset V(n002)=14.59894341 V(out)=0.003793630424 V(n013)=0.6770139189 V(n017)=0.003793630424
+ V(n019)=-25.03608544 V(n008)=15.98437461 V(+vs)=25 V(d1:3)=16.84 V(n016)=-0.005649090107
+ V(in)=0 V(d2:3)=-8.16 V(d3:3)=-8.16 V(n012)=3.907166211 V(n007)=15.98437461 V(n004)=19.93241994
+ V(n005)=4.642203728 V(n009)=0.3860467752 V(n006)=4.642203728 V(n010)=0.3859918457
+ V(n018)=-20.35945837 V(n014)=0 V(-vs)=-25 V(n015)=0.003793630424 V(n011)=0.003849349371
+ V(n022)=-20.35945837 V(n021)=-24.61677347 V(n023)=-20.35945837 V(n024)=-24.61654835
+ V(n001)=4.642203728 V(n003)=0.6770139189 V(n020)=-24.88061479

So, we see the net name in brackets and its value. What could be ther script to put these values at certain nets? This would be a  great help to me in debugging and setting up my boards. Also i attach the picture with the way it's done in Orcad Thank you in advance

Doesn't Altium already have a SPICE simulator built in? Have a look at the documentation to see how it could integrate with schematics, this might be a good place to start:

should be easy to do.
simply iterate over net labels and check if they match your spice net name. then inject a text label below the net label with the voltage.

it's like 20 lines of code
