The functionality of the traffic light controller was tested by giving input (i.e. a car is on the farm-road), and confirmed to work correctly. Since my partner has skipped the lab-hours from lab-5, I had to do all the stages by myself. Hence it was little too tough. Although Xilinx FPGAs are field-re-programmable, I am afraid our design strategy depend too much on the characteristic.
Our design procedures follow the steps below:
In the real world, between step 3 and 4, there is a logic simulation step. I know OrCAD has simulation utility, but cannot try due to limitation of the schedule. In addition. shortage of FPGA board makes debugging more difficult.
