Hey all, I'm porting over the ZCU102 + ADRV9002 reference design to a custom devkit (and then down the line to a custom board). I'm using the TE0701 carrier with the TE0820 SOM. The issue is, some of the FMC differential pairs connect to the IOs with swapped polarity. I initially tried updating the constraints file to reflect how it's physically wired, but Vivado won't let me do that as it actually does check if the physical pin's polarity matches when you use IBUFDS/OBUFDS. So next I tried updating the constraints as if the polarity was correct and just inverting in HDL, but that did not seem to work (interface tuning fails). I also know that the SSI config lets you flip ~some~ signals. But in a previous forumn post it was noted you cant flip RX I/Q individually, only TX.
The following are flipped on my devkit: fpga_mcs_in, rx1_idata_in, rx1_strobe_in, tx1_dclk_out, tx2_strobe_out.
What's the correct way to go about porting the reference design in this case? Where should the polarity be corrected?
