How to debug a pcell on PCELL IDE

dakuang01

Hi there,

I'm trying to debug pcell skill codes. I have two skill files. One is containing pcDefinePCell() to define the pcell and the other is made of the functions to make the pcell work.

I have used SKILL IDE tool to debug some functions but it's the first time I have to debug pcell skill codes.


When I open a test layout cellview, I only see PCELL IDE menu but no SKILL IDE menu under Launch. And the pcell is flattened on the PCELL IDE window so I don't know how I should debug.

I could use some advice.

Thanks,
Jane

  • Hi Jane,

    The PCELL IDE is actually a customized version of the SKILL IDE. You can use it to debug the super master or instances of a PCELL and it has features like cross-highlighting between source code and objects. This is the one that you open from Virtuoso layout editor.
    The "regular" SKILL IDE is launched via CIW - Tools - SKILL IDE. You could open these "other functions" of yours that are called from within pcDefinePCell() in this "regular" SKILL IDE and set a breakpoint. The code execution will then stop at this breakpoint when you create the PCELL super master or place an instance of a not yet existing parameter variant.

    Thanks for your reply, Max.
     
    I should've explained more in details of the issue I'm having. 

    I'm debugging a callback function of two checkboxes named Select All/Deselect All on the Property Editor. What I'm trying to do is to turn on Select All when the other checkboxes are all on. In some cases, it's turned off even though the others are all on.

    That being said, I need to see the change of the checkbox of the pcell and it is flattened on the layout view of PCELL IDE so I can't open the property editor.
