Programming a Traffic Light Controller In verilog using Quartus Prime Lite

ost a question but ill try my luck)

am a student and I have a final project to build a tra ffic light control system using Verilog, and then I am to program my FPGA board which is a De10-lite. I feel like the coding aspect of the project isn't bad. I ha ve cases and such set up to switch the device to diffe rent states based on clock pulses and user input on th e FPGA board. My one question is: how am I supposed to translate my code that I've been working hard on and make it so it will work with the FPGA board. I need my lights to work as the traffic lights ( both north-sou th and east- west roads) and I have pedestrian walk si gnals that can interrupt the traffic lights to let ped estrians cross as well as off peak and peak times dete rmined by a switch. I don't really know how to transla te the code into a function device and the resources I 've been trying to find have been less than helpful. I f this isn't the correct spot to post something about this particular issue could someone point me in a dire ction that can be helpful? Or if this is a spot to get some help? I would greatly appreciate all the help I can get.

Mo st FPGAs have enough drive strength that you can just connect an LED (with current limiting resistor) to th e output and it can make it glow or not. Similarly, a switch (with a pull up resistor) can be brought into an input pin a device.

Your design will have a mod ule at its top level, and the inputs and outputs of t he madule will become pins of the device. You will nee d to use features of the FPGA design software to map your module inputs and outputs to the specific pins y ou have attached the switches and LEDs to.

It loo ks like that board already has a number of displays an d switches attached, so first you need to decide how to map the parts of the board to your 'traffic ligts' and inputs. Then you need to find out what pins thos e connect to with the documentation of the board. Then you can use the FPGA software to map those pins to y our signals.

Unless the OP already has a template design (eg from their professor) it might be worth starting with an example project that already targets that board.

If you download the 'DE10Lite CD-ROM' (which is a Zipfile, don't know why they call it a CD) from here:

there's usually a series of example projects. Terasic usually provide a 'Golden Top' project which is an empty shell that's ready for you to drop your code into (there are other projects for talking to things like Ethernet and off-chip memory, which you don't need for now).

Wiring up your code to the clock and LEDs provided in that project should be fairly straightforward (a few minutes work), and then you can build it in Quartus.
