VHDL - Accessing signals through strings

Default Accessing signals through strings


Hello,

Does anyone know how to access a signals' value by referencing that
signal name though a string?

e.g. I am reading in my signal names from a file.

I then wish to print back out to a file the corresponding signal
values.

Hope that is clear.

Regards
John

Not in VHDL, unless you write a very frightening "case"
statement.

If you are using ModelSim, you should check out the
"SignalSpy" tool. Otherwise, it's something that you
could do through the simulator's C-language interface.
