Search for all instances of a specific cell within a hierarchy

Kevin Buck

I'm trying to find a functionality I expect exists in Cadence but I don't see it in the documentation. I want to find all occurrences of a specific cell within a hierarchy. For example, I have a cell called 'analog_top' and I want to find every instance of a cell called 'cellName' down within 'analog_top' and anywhere lower in the hierarchy from this cell. Is there a built in function to do this? Thanks.

  • Dear Kevin,

    Perhaps I am misunderstanding your question, but the hierarchy search feature is available as a Virtuoso menu item. Figure 1 shows the menu item, and Figure 2 shows an example of the resulting dialog panel where I specify a schematic hierarchy search for a particular cellname. Clicking the "List All" radio button in Figure 2 will provide a list of all matching cells in the schematic hierarchy in the CIW. Figure 3 shows the resulting list in a screenshot of the resulting CIW list. I've highlighted the 8 instances of the cell that are identified below the count of 8 in the level of hierarchy in which they occur.

    I hope this is what you are looking to find!
