Altium: fetch nets of components from schematic alone with DelphiScript
If you have a nameing convention in your schematic to name the net by the voltage value you can generate a netlist via the outjob and parse it in the script. The sript could be started by the outjob.
There are many diferent types of netlist outputs, try witch one is easier to parse by your script.
For example:
Calay Netlist:
/1V25_STBY C4101(2) C4106(1) R4102(2) R4144(1) TP4176(1) U4100(G8) U4100(H7);
/13V5_RPS  C6301(2) C6308(2) C6314(1) C6317(2) R6322(2) R6325(2) T6343(1);
A script could be:
If netname starts with a number treat it as a Voltage value.
If Component name starts with C treat it as a capacitor.
add or change component parameter &quot;used voltage&quot; to extracted voltage from netname.
