An iverilog program displaying the working of RING and JOHNSONS counter with the Timing diagram in GTK wave.

RING-AND-JOHNSONS-COUNTER

SYNOPSIS

A simple iverilog program to implement Ring and Johnsons Counter

DESCRIPTION

• In each folder there are 2 .v (Verilog files) i.e. tb.v and md.v which are the execution and declaration files respectively.
• On execution, we can get to see the Clocking Diagram (GUI mode) of both the Counters in GTK wave.
• Can work both on Windows and Linux systems.

INSTRUCTIONS

• Please install iverilog and GTKwave if not done. Then follow the remaining steps.

JOHNSONS COUNTER

• First open a terminal in JOHNSONS COUNTER and run the following.

iverilog -o jc tb.v md.v

vvp jc

• At this stage we get the output in console. To see the GUI Clocking diagram, execute the following :-

gtkwave JOHNSON_COUNTER.vcd

RING COUNTER

• First open a terminal in RING COUNTER and run the following.

iverilog -o rc tb.v md.v

vvp rc

• At this stage we get the output in console. To see the GUI Clocking diagram, execute the following :-

gtkwave RING_COUNTER.vcd

• So, this was the simple project about!
