I'm trying to build a project on my Zybo where I would route both USB and Ethernet signals trough my PL, instead of them going directly to PS. Now, to my understanding, what I should do is route those signals trough EMIO ports on Zynq. Looking trough Zybo datasheet I see that USB signals such as OTG_DATA[7:0], OTG_NXT, OTG_STP and so on are routed to pins: A14, D15, A12 and so on. So, per my understanding of using EMIO pins, I should be able to put those values in XDC file and Vivado would route those signals trough EMIO. When I open Net View, I see all the signals I expect to see: ulpi_data_io[7:0], ulpi_clk, and so on. So I want to set up those nets to be routed to my selected pins.
However, when I try to input values found in Zybo datasheet, Vivado won't let me select some of the pins, it says that location is unavailable.
Am I doing something wrong? What is the correct way of assigning USB and Ethernet pins to EMIO port, instead of them being routed to PS by default?
