Entering ASCII test values in ModelSim

Altera_Forum · ‎05-21-2012

Hello everyone,

I am new to the ModelSim software and had a question regarding ASCII test values. At the moment, I am comfortable with the "Create Wave" function where I can establish a clock, a constant, etc. with one of my signals. However, I have no clue how to assign an ASCII value to one of my inputs and have it displayed in the Wave window. My project is a state machine that logs ASCII inputs and will generate a '1' output when 'm', 'p', and '3' are entered sequentially. Thank you in advance for your help!

VHDL Character-to-integer conversion:


variable c : character;
variable i  : integer;
i := character'pos(c);

VHDL Integer-to-character conversion:


 c := character'val(i);

Cheers,
