    Hi Hatim,

    Unfortunately, I don't know much about the PSpice model. I'm checking to see if this is a known error but the team behind the model isn't available for contact anymore so we don't have much to go on for debugging.

    I would recommend checking externally for PSpice focused advice online. After searching this error code in a browser I saw that there were a few forum posts on other websites that may give you the answer you need.

    Regards,

    James

    Hi Hatim,

    Try this fixed LIB file and see if that solves your issue - TPS65218xx_DCDC2_TRANS_fixed.LIB

    I received the following comment from someone with PSpice modeling experience about the error:

    "For some reason there are two extra curly brackets in the model LIB file. One on line 110 and second on line 130"

     

    "Model should be working after the modification:"

    Regards,

    James
