EEE 333, ASU, D.Allee Lecture 03 - 3 - What Are We Doing Here? This class is about “hardware description languages” and implementing digital designs in FPGAs Much of the class is about learning VHDL, which looks like a programming language However, it is important to remember that the goal is to build digital hardware In general it helps to remember (always) that you’re building hardware The important implications are Your code must be synthesizable to be of value You have to think a lot about the timing of events So we’ll start with a quick review of digital logic basics

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
