THS4541: Using PSPICE model in ADS 2019

Part Number: THS4541
Other Parts Discussed in Thread: TINA-TI

Hello all,

I wanted to see if anyone had insight into using the PSPICE models provided on the TI website in ADS 2019. I have gone through the import procedure for the model, but end up with a schematic component that has no pins and doesn't resemble an op-amp (it appears to be a default template component with the text "PORT"). I attempted to modify the schematic component to add pins, but I cannot find out how to assign these pins to nodes within the model ,so if I try to simulate I get errors that pins aren't connected. Has anyone done something like this previously who could provide insight?

Thanks for your help.

    Hello Ben,

    Not sure what is going wrong here, but pins within the model are labeled as such:

    VOUTM VOUTP VOCM VINM VINP VEE VCC PD

    Hopefully this might help you in adding pins to the imported device.

    Hi Hasan,

    Thanks so much for your reply. Per your suggestion, I assigned those pins to the imported netlist. However, now I am getting the following error:

    ERROR: (stdcmds.ael line 282, column 5)
    Error generating netlist for "GlitchFilter_lib:cell_1:schematic": Failed to create netlist:
    There is no corresponding terminal for `PD' in the netlisted view `IFF_THS4541_lib:UNNAMED:schematic'.

    It appears that ADS is not "discovering" the pins within the netlist and therefore isn't able to assign them. I've looked around for a way to list the pins within an imported netlist to check that they're not listed under different names but haven't had any luck. I've attached a picture of my imported schematic symbol. Do you have any ideas what could be the issue here?

    Again, thanks so much for your help.

    Best,

    Ben

    Hello Ben,

    Sorry not sure what the issue here in this case. The model can be used in both TINA-TI and Pspice, perhaps Keysight forums are better suited for issues importing the SPICE models into ADS.
