  1. Hello, I have a Nexys Video and a Digilent Sevent Segment Display PMOD. I want to drive the Sevent Segment Display using the Nexys Video. The only two matching PMOD headers are JB and JC but they are are marked on the manual (https://reference.digilentinc.com/reference/programmable-logic/nexys-video/reference-manual) as "differential". However, on the Digilent provided XDC constraints file, the pins are individually controllable and marked as LVCMOS33. Can I use those pins as normal single ended PMOD to drive the seven segment display? Thanks!
  2. Hello everyone! I have ordered my first FPGA. I think I understand VHDL (I have been reading some books about it). My problem is with the toolchain. I don't understand how to use Vivado properly, and the information I find online is really confusing and frustrating. Digilent's tutorial about Vivado is good, but doesn't really get into a lot of detail. What is a good resource for learning Vivado? I would love to know the syntax of constraints, how IP cores really work, how to simulate and testbench, how to analyze the generated hardware properly... Thank you very much!
