Top level implementation is done the same as it is for standard designs, except for the addition of the following steps.
- Set the HD.PARTITION property on each black box cell to be resolved with OOC
implementation results.Note: The HD.PARTITION property is imported with the OOC module as well, assuming it was set in the OOC implementation. However, it helps to ensure the cell is properly marked by setting it on the top-level black box instance.
- Read an OOC checkpoint for each partitioned instance.
- Choose the level of preservation to maintain (logical, placement, or routing).
