When running the testbench given, i get this output:

I'm trying to understand the test bench, and i'll continue to do so, but i thought i might ask here in case the dev has an answer for me. Thanks!

Hello, I am getting the same error. Did you figure out what the problem was?

[ibm2030]

Hello, sorry for the delay. For both of you - which VHDL system are you using (ISE/Vivado/something else) and are you using the code exactly as here? I will try to replicate the problem.

Hello! I was trying it on Xilinx ISE Design Suite.

Same here. I'm using 14.7, with the code unchanged.
