RE: Can't run schematicFind in a nested loop without GUI

jorankin

Hello,

   I am using cadence icfb version 6.1.4.500.8. I am writing to see if you can help me with the following:

   I am trying to run the following commands in a nested for loop:

 

hiiSetCurrentForm('schSchFindForm)
schSchFindForm->schFindPropNameCyclic->value="cellName"
schSchFindForm->schFindPropValueString->value="nmos"
schSchFindForm->schFindSearchScope->value="hierarchy"
schSchFindForm->schFindZoomButton->value= t

n=t

i=0;

while(n

       if(i==0

       then

         schFindSelectObject();

       else

        schFindObject("next");

        schFindSelectObject();

        );if

       ...operations on selected instance

       ...logic to figure out if I've found all the instances, set n=nil if I have

);while

 

The problem is that, given the sch SKILL functions, I can't find a way to get out of this loop once I have selected all of the instances without knowing a priori the number of instances I will find. When i have selected all the instances, a window comes up saying that there are no more to search for, but nothing is actually returned that will let me get out of my while loop.

 

Can you help?

 

Thanks,

John

    John,

    A bit messy (I probably wouldn't use the find user interface for a batch operation like this), but something like:

    lastReached=nil
    first=t
    while(!lastReached
      if(first then
        schFindSelectObject()
        first=nil
      else
        if(schSetCurrentObject("schFindList" "next") then
          schSetCurrentObject("schFindList" "previous")
          schFindObject("next")
          schFindSelectObject()
          ; do what you want here
        else
          lastReached=t
        )
      )
    )

    Bear in mind that some of the functions here (including those in your code) are undocumented and liable to change in future versions.

    Regards,

    Andrew.
