PLD Homework Problem 2 (Combinational)

EE-290, Spring '97, Dr. C. S. Tritt
Due 4/28


Create a text design file using MAX+plus II or PLDshell Plus for a 4-bit binary magnitude comparator like the one described in section 5-4 in your text.

I do not recommend you use a truth table for this design as it would contain 256 lines. If you use equations, define some "intermediate variables (nodes)" like the ones used in the example in your text. This will involve using a VARIABLE section in MAX+plus II or STRING's in PLDshell Plus. An alternative to equations (at least in MAX+plus II) is to use "IF THEN Statement Logic."

Turn in printouts of your MAX+plus II .tdf and .rpt files or PLDshell Plus .rpt file. Save your design file for use in PLD Homework Problem 3.
