How to traverse the hierarchy in a schematic

Hi,

I am totally new to SKILL. I am trying to write a skill routine to traverse the hierarchy of a schematic. Basically I want to pick each port at the top schematic and go down the hierarchy tracing each net down the hierarchy and listing out to which pin it connects to for certain type of components.

What functions can help me in:

1. Listing out the ports on the schematic

2. Listing out the subcircuits in the schematics that I can open and go inside

3. Trace a net to find the components connected to it on a particular schematic.

Thanks.

Hi aryajur

Hope that solution 11685440 can give you an idea of how to transverse a schematic design. Maybe you can start from there. : )

This is the part that does the transversing. It calls a procedure recursively.

      foreach( master cv~>instances~>master
         nextCv=master
         cond(
            (!nextCv nil)
            (member(nextCv masterList) nil)
            (t
               nextCv2=dbOpenCellViewByType(nextCv~>libName nextCv~>cellName "schematic" "" "a")
	       getWarn()
               when( nextCv2
                  masterList=CCSfindAndChange(outPort nextCv2 pattern 
				checkAndFix ignoreBusInst cons(nextCv list(masterList)))
               ) ;when
            ) ;t
         ) ;cond
      ) ;foreach
