Core doesn't work in block design in 2018.2.1 #1

Unfortunately, it seems like this core does not drop cleanly into the latest version of Vivado.

Here is the error output when trying to add to a block design:

Still getting the same error with nekomona's fix when I tried with vivado 2020.1 in windows.

Fixed here: https://github.com/apullin/vivado-picorv32/tree/vivado-2020.2

At least insofar as being able to drop it into a block design, add peripherals, and result in something that will synthesize and implement.

I don't know enough yet to be able to get this up and running, so if someone could verify that, please do and let me know!
