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.

Hi Sai,

Please use the below config file and there are few errors that are expected.

/project/mercury_test/giant/giant-2025.1.2/mm890906/FN.1_iter0/impl/mercury_top/release/40_scan_v8/sbus_qmmi_qmmi_pll_wrapper_0.trc_config.multi_mode.flattened

[24/10]

I have updated the trc config file on the path below. Kindly please take the trc config file from below path and update in your flow.

/project/mercury_test/giant/giant-2025.1.2/mm890906/FN.1_iter0/impl/mercury_top/release/40_scan_v8/

You will see some errors for hm_io_e and pcie_ss_pcie_0 , that you can ignore.

[27/10]

for hm_io_pm,

trc++ -p -j -l -T -t ,  switch -j is not needed as this is not IO block and no boundary scan chain.
