Not everything the FPGA does -- register format/contents, FIFO widths, etc --
can be
error checked. There has to be some reasonable expectation on the software
side.
The typical method is a "revision id" register, the software checks this and
adjusts
capabilities. If the revision is too far behind or doesn't match expectation
then
the software gives an error message.
