Fpga setup and hold time

WebMar 6, 2015 · The delays between DRF and FPGA can be different for each signal due to different trace length on our PCB. Hence, we need to know the setup time and hold time needed by the axi_ad9361 hdl logic in order to receive correctly the rx data. This will help us to define a mximum allowable difference in trace length on our PCB. WebMay 9, 2024 · Most recent answer.
