Stop XStream from custom skill procedure

Adrian Nistor

Hello,

I know that XStream is passing each cell to some functions like poParamCellNameMap() or poCellNameMap() in order to change the name of the cells inside the exported gds file; My problem is that I would like to stop the process if I detect one PCell which has some problems.

Is there any possibility to make this ?

 

(More details about my problem: I want to detect PCells which can not be created (functions missing, errors, etc) in the layout; The layouter can load locally made pcell scripts, he can have a pcell layout in he's layour, but when he will export to stream/gds, that locally created pcell will be skipped (for some reasons we maintain "Stream out from virtual memory" disabled and we do not want to enable it). I would like to detect cases like this during the process of exporting and, using a skill script to analyze, to stop te exporting process)

 (I'm using Virtuoso 6.1.4)

 

 

Thank you,

Best Regards,

Adrian

  •  Hello,

    Thanks Derek

    It is disabled, I also noticed that option.

    I tried to make the problem more clear; I have one pcell which starts with something like:

    If( isCallable(theBigPcellFunction) then

        theBigPcellFunction(....)

    else

       put_an_error_marker_in_layout

    )

     

    And I have the original layout with that pcell (which is only a marker because I did not loaded also the big function in order to have the possibility to make tha screenshot. I export to Stream; then I import the gds file back in Cadence, and I open it; 

    the result:

    The Pcell which initially had only an error marker and a label to explain the marker, after export and import, it;s just ... somthing selectable but with nothing inside !

    This kind of cases I want to avoid.

     

     

    Thank you,
