I'm a kernel-level software engineer with a solid knowledge of hardware from the interface level up. I want to move into hardware design and would like to see myself, in 3 years as an RTL engineer working in the semiconductor industry. I, however, have no understanding of this space beyond college level introductory electronics classes and while I could go away and do a whole CS/EE degree I have neither the time nor the finances to do so. On the other hand, I think doing a single RTL course is unlikely the best way forward as there will be gaps in my knowledge. What would be your recommendation on the best path to get from where I am to where I want to go? I'm not averse to spending money to do so as long as I can do it in evenings/weekends?
