Dear FvM

Thanks for your reply.

As far as I knew, undefined signals ('U's) could not be detected since they are "undefined."

But I just tried to detect them using "if" statements (like 


if not(dataa(i) = '1') and not(dataa(i) = '0') then
--blahblahblah

) in my VHDL, I noticed I could detect them.

Sorry for my poor understanding...

Anyway, using the logic above, I could deal with my problem.

Thanks alot, Fvm
