Occasional ContributorDo we need to manually Pin map HBM m2u Interface ports
Critical Warning (12677): No exact pin location assignment(s) for 40 pins of 72 total pins. For the list of pins please refer to the I/O Assignment Warnings table in the fitter report
Getting following Critical Warning in fit.plan.rpt
The un-mapped 40 pins are the following m2u interface ports exported from HBM controller instances
///// HBM m2u bridge signals /////
input wire hbm_b_m2u_bridge_cattrip, // hbm_b_m2u_bridge.cattrip

Do we really need to map these ports to FPGA IO Pins ?
How can I fix this Critical Warning?

Hi Siva Kona,
Right. HBM m2u bridge conduit interface are connected to inbuilt HBM PHY. There is nothing to do with the FPGA IO pins so you can just leave the ports and ignore the warning. Those ports will be connected externally.
If you want to do some simulation on this HBM controller instances (HBM m2u), you can also just ignore the critical warning as it'll not affect the result as long as there is no error.
However if you want to simulate HBM m2u connected to HBM PHY, you should make sure the ports of both instances are connected properly.
Hope it helps.
Best regards,
Sheng
