@stenzer thank you for replying to me – it is good to see there are somebody here
I have already seen those links you have listed.
I have tried the first one (link) and cannot get the .SUBCKT to work in the script.
The second one (link) require a schematic subcircuit and I donÂ’t have a subcircuit to put into Proteus spice engine.
The third one (link) is a guy who thinks Proteus is running PSPICE, but is told that Proteus is running SPICE3F5 – I think nowadays it is PROSPICE and not SPICE3F5 but I’m not sure…
I have tried to look into SPICE1.DSN and SPICE2.DSN files but they are not in the Proteus v 8.9.
So what I need to somebody to help me to get from PSPICE to PROSPICE in general, but of cause if somebody can help me with this specific issue – the attached file – that would be great
