    Hello All,

    I am stuck with this problem from a quite long time.

    I have a model file as given in "Transistor Model.zip", which is written for HSpice. I am trying to work with that model in LTSpice.
    The second file "Capture.PNG" shows my attempt. When I try to run the simulation, I get an error saying

    Fatal Error: Missing expression in "equisbbd(sbbda, sbbdb) = {sbbda*(to8(1-p))+sbbdb*(1-to8(1-p))}"

    But the expression is right there in the model file.

    I tried to use function instead of that expression but it did not solve my problem. I would appreciate your kind help.

    It's not saying the quoted text itself is missing; it's saying there's something missing in the quoted text.
    Maybe missing some '*' operands?
    Try modifying the part "(to8(1-p))+sbbdb*(1-to8(1-p))" to "(to8*(1-p))+sbbdb*(1-to8*(1-p))"
