Course feedback

Huge thanks to Matt Venn for creating the phenomenal Zero to ASIC course and making chip design accessible to beginners like me. The course structure, step-by-step tutorials, and Matt's dedication to answering every doubt made this complex field understandable. Even more generous was the discounted course access and free tile opportunity!
