Layout XL pointing to wrong schematic Design

jimstuy

Hi all:

    I am working on the layout of my chip right now, and I am coming across something peculiar...In the library manager I copied my design cell to a new cell with a different revision. In the old cell, I have done partial layout of the cell in Layout XL. In the new cell, I fire up the layout of the chip, and open with Layout XL, and when I try to cross probe, it is pointing to the schematic of the older cell, rather than the newer cell. How can I correct this error? Thanks so much for your help!

  •  Hi,

    after opening the Layout in XL mode, do the following so that you cann't the problem again.

    Connectivity(Menu in Layout View) ---> Update ---> Connectivity Reference....

    it will gives a popup there fill the newer Schematic library name, cell name, view name

    then apply this will updates your copied layout with newer schematic

     

    Thanks & Regards

  • Hi

    Sorry for bumping this thread however it is relevant to my question.  I have the same issue, I have copied an entire library from Lib to Lib_B and wanted it hierarchial, and if I descend from top cell in schematic and layout within my design they do all reference Lib_B.  However if I open Layout XL from a layout it opens the schematic from Lib rather than Lib_B (opening Layout XL from schematic works correctly).  I can use the solution provided above for an individual cell, but as I have a few hundred cells within my library this is boring and time consuming task.  Is there a way to do the copy so this does not happen, or a way to update the library reference (as in the solution above) for a whole library?

     

    Many thanks

  • You'd need to traverse all the cells, and call lxSetConnRef() with appropriate arguments for each. See the documentation for details on using this function.

    Take a look at Solution 11420192 which provides a way to trigger it to do the update during the copy (in IC5141; it shouldn't be necessary in IC61X versions as it should do it anyway - you didn't say which version you're using). Or Solution 11267054 which gives you some code to update the connectivity source for everything in a library.

    Regards,

    Andrew.
