Dear colleagues,
I wonder if there any pre-defined numbers for IDELAY modules for STEMlab 125-14 4-Input Starter Kit. The point is that there is no any information about PCB trace lengths or some default variables for the modules.
In case "default" variables from here: https://github.com/RedPitaya/RedPitaya-FPGA/blob/58895f250ee65d646cca7a7c1218f652a8a893fd/prj/v0.94/rtl/red_pitaya_top_4ADC.sv#L395 we face unstable ADC work. Also, there is nothing about IDELAY in the RedPitaya EcoSystem repository.
Ok, it was my mistake. The same filename red_pitaya_4ADC.xdc but relates to the different revisions
red_pitaya_4ADC.xdc
