After some random browsing on the internet, I discovered my digital hardware project is publicly out there on the internet.
I had ambitious dreams back then. I convinced my partner we are going to build a VOIP application on an FPGA using merely the laboratory time in one course. I even manage to secure a $2,000 piece of hardware from Xilinx as well as the expensive programming and simulation software. At the end of the course, we don't have an operational prototype, nonetheless it was a valuable learning experience.
Without further ado, here is the write-up of the project.
