Classification: UK OFFICIAL Hi, I'm trying to add support for an FMCOMMS 3 to an existing BSP for the ZCU102. The BSP is provided on Github by Geontech<https://github.com/Geontech/bsp_zcu1xx>, as is my current fork of that project<https://github.com/domWalters/bsp_zcu1xx> with the additions that I have made so far. As the ZCU102 is an Ultrascale based board, this BSP requires Geontech's OpenCPI<https://github.com/Geontech/opencpi/tree/release_1.4_zynq_ultra> version which supports Ultrascale (Although I don't think this impacts my question). Geontech's BSP didn't enable use of the FMC slot so I took guidance from the Zedboard BSP and replicated the xml for my specific FMC pinout. One area that I'm confused in is what I should do in the timing section of the fmcomms .xcd file. Specifically from line 215 to 431<https://github.com/domWalters/bsp_zcu1xx/blob/release_1.4_zynq_ultra/hdl/platforms/zcu102/fmcomms_2_3_lpc_ad9361_adc_sub_ad9361_dac_sub_LVDS.xdc> the existing zedboard fmcomms3 xdc sets a large number of input delays. How would I go about recreating this section for my ZCU102?
