1,what is the different between signal and variables in VHDL? 2,what is the different between fun..

Answer / jimmy.gugon

Hello,
A function returns 1 value whereas a procedure can return
multiple values? Could someone elucidate this for me? Also, I
am confused about the scope of signals. If I declare a signal
within an architecture, does the scope of this signal extend
to functions declared within processes in the architecture? If
not, is there a way to do this without passing the signals? I
would like to call functions in a way resembling scripts that
allowed for greater code readability.
