Reading Inherited Net names from the current cellview

Hi,

 I am having difficulty reading the inherited net names of a schematic. I have a schematic with inherited connections for VDD!, VSS!, VNW! and VPW!. At the upper layer of hierarchy I have set the net expression properties to ensure these nets are connected to avdd, gnd, vsubn, vsubp.

 Starting from the toplevel schematic, I descend into the lower level instance so that I can see the inheritied net names avdd, gnd, vsubn and vsubp annotated on the schematic. However if I use cvId~>nets it only returns the global net names.

My code is:

;; Get ID of toplevel schematic

topId = geGetEditCellView()

 

 ;; Descend into instance "cellA"

instName = "cellA"

 instId = dbGetInstanceByName(topId instName)

geSwitch(hiGetCurrentWindow() "r" instId 0 1 1)

 

;; Print a list of nets

 cellId = geGetEditCellView()

foreach( netId cellId~>nets

   printf("NetName: %s\n" netId~>name)

)

 

This only prints out the global net names. Not the inherited net names. Is it possible to access a list of the inherited net names?
