Excellent course on digital IC design. Heavy workload of assignments and labs, but they make you learn the material very well.

Highly useful before taking grad level digital ic design classes.

Excellent prof. the course lectures are available on youtube, but the course rigour helps solidify the concepts. Had amazing TAs too, so made learning very fun.

Read the West and Harris book (available as a free pdf) for part you dont understand. The class content closely follows the book, although the lectures are sufficient.
