Notes:

1. Perform Tag/Watermark check on the netlist.

2. Restore the database with latest nelists and place the unplaced TEST* ports.

3. Provide floorplan LEF's after going through the default pad block flow for TLR purpose.

4. We will incrementally review the pin placement and do necessary changes. (hm_io_e <=> hm_ae interface, and if any other interface to reduce the TLR route.)

5. Please share the Drop Sheet which captures the Top & Mike Ho Drops (DEF). Maintain all the issues consolidated in the same sheet to discuss with Mike for any additional changes.

6. TIE cells' pitch needs to be tighter in the pad block please review.
