PSpice netlist, no ground net problem

LegendofPedro

I'm having serious problems modelling the infinite resistor grid problem. When creating a PSpice netlist from OrCAD I am being told that I haven't included a ground net. However, I have added plenty of ground symbols (Place->Ground) and have ensured that the net name is "0".

Any ideas about what's going wrong here?

Regards,
Pedro

OrCAD/pspice error

    You likely have connect the 0 net to an overriding object, like an off-page connector or hierarchical port. Select the DSN file in the Project Manager window and use File>Archive Project, create a single archive and attach the resulting ZIP to the forum so that the exact data, rather than just a screenshot, can be examined.

    Thanks for the advice. I couldn't find any extra parts off-screen and my heirarchical block does not contain a GND symbol.

    I have attached the archive as requested.

    This seems to be fine for me. It looks like you might be running 16.5, check that you have the latest hotfix installed, if not, get this applied and then see what you get when you run the simulation.

    Indeed, my university is running v16.3. I've been going mad trying to work out why my design wasn't working and my lab demonstrators haven't been able to help. Thank you for looking into it, I'll contact the IT department and see if an upgraded version can be installed.

    Your design has two simulation profile and both of these are working fine in version 16.3 at my end. Can you name simulation profile where you are facing this problem? Is this "SCHEMATIC1-transient" or "inf-transient"? Also share the .out file when you get this error since we can not see the error at our end with same design.

    Having your installation updated to 16.6 is anyway good idea.
