Hello,
I am using MicroZed 7020, industrial temp version, with a custom carrier board developed in-house. I am trying to calculate some signal propagation times to enter into Vivado as "set_input_delay" and "set_output_delay" constraints. I am new to this so I may be misunderstanding something very basic or simply not know where to look in the docs for the info I need. But my understanding so far is that to calculate the propagation time between a Zynq IO port and the corresponding pin on the MicroZed JX1/JX2 connector, I need to know the length of the net in the MicroZed PCB itself, as well as the propagation speed in that net. I found the list of net lengths for the MicroZed. So for example, if I am using Zynq pin T14, which is connected to JX1.23 by the net JX1_LVDS_4_P, I can look up and see that the length of JX1_LVDS_4_P in rev G of the MicroZed is 2163.282mils. But how do I figure out the propagation speed? My understanding is that it depends on the materials used in the MicroZed PCB. Is that info in the documentation somewhere? Thanks very much!
