I have a P&R-ed design (let's call it MultiA) in Encounter with no violations. I'm trying to export it in Virtuoso using OA database. While doing this, I receive the following errors:
**ERROR: (ENCOAX-41): Cannot create an instance in a hierarchy where the occurrences are not unique
**ERROR: (ENCOAX-347): Could not create instance 'pixel_7/FILLER_impl0_19' in OA. Refer to any earlier messages.
The final result is then a design _without_ fillers. The other cells are anyway present.
You should notice that:
- I can successfully export another design (in the same OA library). Let's say this is called SingleA.
- The wrong design(MultiA) contains many instances of design SingleA. I'm reading in the netlist of design SingleA and then I'm placing many copies of this design.
Could you please point to what might be the error source?
Thanks in advance for the help,
