List of cells and their dependencies from a library

strotta

Hi,

Is there any way to obtain on an easy way a list of cells of a library an their dependencies ?

For example:
Library: myLibrary

There are three cells:
cell 1
cell 2
cell 3

I could obtain a list of them using ddGetLibList and choosing my library:

libs = ddGetLibList()
proj_name = myLibrary

(foreach i libs
    (if i~>name==proj_name then
        proj = i
    )
)

Now, I would like to see what sub-cells or instances are inside of each cell. For example, cell 2 could be used inside of cell 1. I can't get that info on this way then If anyone could clarify me how to do that really appreciate.

Thanks in advance!

    Hi Santiago,

    Well essentially you need to recursively traverse a design hierarchy following the master cells being referenced by instances. There a various articles how to do that, for example:

    https://support.cadence.com/apex/ArticleAttachmentPortal?id=a1O0V000007Mn1KUAS&pageName=ArticleContent

    However it's not quite that trivial - there is other types of references to other cells than just instances. For example a a VXL layout view has a so called connectivity reference pointing to the schematic iw was generated from. Or you might have a config view for a schematic. And Pcells where an instance references so called submasters deserve special attention.

    So to answer your question "Is there any way to obtain on an easy way a list of cells of a library " - I'am afraid the answer is no, not really an easy way.
