Getting information on cell instance

ssarik

Hi,

Is there any quick way by which I can know which designs have an instance of a cell from my library.

For example:

There are n libraries, I have designed a cell 'X' in one of the library 'Y'. How can I know which all cellview in the 'n' libraries has an instance of 'X'

Thanks,

Shahbaz

  • There is no connection from a cell view master to the cells which place it so you have to search through all the cells in your libraries for instance headers which match the lib/cell/view.

    The simplest method is to loop through the cells in your library

    1. Open each cellView Read Only.
    2. Search the instHeaders of the view for masters with the same lib/cell/view name (or lib/cell name). This is much faster than searching the instances because an IH can point to hundreds of instances.
    3. If the matching IH is found, you can get individual instance information directly from the IH.
    4. Record your findings.
    5. Close the cellView so you don't leave lots of open files.
    6. Do the next one till you run out of cellViews.
