What setting (#data bits, #stop bits, #parity bits) is required for the miniproject?
Check the settings in the HyperTerminal program. In the receiver module, we have one big always @ (posedge clk) loop and the RxD changes within that. Isn’t that the same as putting a DFF on the RxD…If not how do you do put a DFF on the RxD. They are different because you don’t know how the synthesis tool (FPGA Express) implements the circuit from that always block. To be safe, a D FF should be explicitly used to resynchronize the RxD signal. I worked on the ltring for our group, and I noticed that design manager doesn’t like it when reset is assigned to the sw1 pushbutton pin. When I remove that assignment from the ring ucf file, DM runs the implementation with no errors. It seems to want to assign the reset signal to another specific pin (forgot which one exactly). It’s strange because I just modified the given ring .v and .ucf files, and they worked ok for the tutorial design. That error is from how you write the Verilog code. The synthesis perceives and treats the “reset” signal a
