SKILL descend into a component sub-circuit schematic

Dear all,

I'm currently working on a impedance matching tool that will be run using Cadence SKILL and OCEAN and have stumbled upon a small problem.

I'd like to do the following:

1) Open an existing schematic that has components inside. Each of the components have sub-circuits inside, but they are not parametric cells.

2) Descend into a particular component and change the value of a component which is inside the sub-circuit parameter.

In other words I have a top level schematic A that has a component B. And I want to access component C parameters which is a sub-circuit inside of a component B in the top level schematic A.

I know how to open a schematic, find and change the parameters of an existing component (in this case it is component "Cpad1" in a schematic "ind_lossy" in a library LIB_NAME):

    cvIdTemp = dbOpenCellViewByType(LIB_NAME "ind_lossy" "schematic")
    dbReopen(cvIdTemp "a") ;to remove locked status of the opened cell view
    
    instanceSelection= dbFindAnyInstByName(cvIdTemp "Cpad1")
    
    instanceSelection~>c = 123e-12
    dbSave(cvIdTemp)
    dbClose(cvIdTemp)

I was wondering - how would one descend into a component sub-circuit schematic and change parameters inside using SKILL, save and close both the sub-circuit and the top schematic?

Thanks,

Aleksandr
