Title: Change library binding of cell in hierarchy editor
Post by mohta on Mar 13^th, 2007, 4:29pm

Hello everyone:

I am using Cadence IC5.141USR4. My problem concerns Hierarchy Editor.

In hierarchy editor "Cell Bindings" list, I have a line like the following
Library Cell View Found View to Use
vault myCell schematic schematic

vault is a controlled (and, in this case, locked) library to which I cannot add cells or views. myCell is located deep in the hierarchy of the simulation bench - and all of the cells it has are in vault.

For simulation, I want to change myCell to point to the view "schematic" in my local library "myLib" (not "vault"), i.e. I want to change the library binding of the cell, not the view binding. How can this be done in hierarchy editor?

I cannot seem to right click on the Library column and choose among the different libraries I have, just like what I do for setting the views. Right now, the only option I have is to modify the netlist by hand, or copying all the cells above myCell in the hierarchy from vault to myLib and manually change the bench hierarchy to point to the right myCell view in myLib.

Thanks,
mohta

It is not possible to change the library bindings of schematic views - they are fixed at source. Library bindings can be overridden for things like verilog views, since verilog doesn't really have a concept of libraries.
