How to find the pin mapping for connecting Zybo Z7-20 or Nexyx A7 board to a computer over USB-JTAG?
Hello. In my project, I am trying to run NEORV32 processor in an FPGA. My plan is to perform debugging of the design over JTAG after running it on an FPGA. I currently have a Zybo Z7-20 and a Nexyx A7 board at hand. As per my understanding, for both of the boards, I need to find the board pins associated with JTAG and manually connect them through the constraint file. I was going through the reference manuals for both FPGAs but couldn't find the pins that need to be connected.

Synthesizable LFSR counter (feedback 16,13)
This TRNG (VHDL) provides some kind of "imulation mode where the entropy source is replaced by a LFSR. When simulated, the testbench prints the random data to the simulator console. Maybe this can help as starting point.
