pCell need load .il file every time I open icfb

richardyuan

Every time I open the cell containing my pCell instance from a new terminal, it has a label "pCellEvalFailed" and cannot reveal some of the layers. The log has warning:

 ("eval" 3 t nil ("*Error* eval: undefined function" TTPointInGap))

But actually the function has been defined in the .il file. And after I load the file in the CIW, all the layers look normal.

What can I do if I want to use the pCell instance without load the .il file every time?

    When you define a Pcell using pcDefinePCell or similar, only the code in the body of the pcDefinePCell is stored in the cellView. Any user-defined functions which are called from the Pcell body that happen to be loaded are not stored. So these need to be defined at run time. 

    Typically any auxiliary functions you need would be defined in or loaded from a libInit.il file  within your Pcell library. This file is loaded upon first access to the library and consequently is a good place to define such functions. It's better than using .cdsinit because not all tools read the .cdsinit (strmout, to name just one).

    Regards,

    Thank you andrew. 

    I can not find libInit.il file in my library. So I create a libInit.il file in the library and move all the functions to it. And it works well now.
