End of Semester – Still alive and kicking!

This week marked the end of a very intense semester in my graduate program. I had planned to just take Power Electronics and then a business or engineering management-type elective, but a course in advanced ASIC design topics was offered and I signed up. The course was split into two sections: SystemC modeling and then back-end physical design for ASICs. It turned out that both of courses were very intense, and trying to complete all of the course work on top of my full-time job was very challenging. I made it through it all though with solid grades. In the ASIC course, I learned a lot about ARM CPUs, especially the buses (AHB, AXB) that interface with peripheral devices, and I learned a lot about DDR memories too. SystemC was quite interesting, a very interesting way to model a system-on-chip (SoC). As a C++ programmer I really liked working with SystemC!  Most of all though, I thoroughly enjoyed the back-end design: placing standard cells, power/ground networks, clock-tree routing, and data signal wire routing. There are lots of algorithms going on in tools like Synopsys IC Compiler and Synopsys PrimeTime, the clustering and routing algorithms alone are fascinating for those interested in applications of algorithms.

Below is a screen capture of my clock-tree in an ARM CortexM0 design. It reminds me of a fractal in some ways! All in all it was a really useful course, and working with ASICs always makes me think about trying to find a job in the semiconductor industry…fascinating technology.

I plan to finish the program and “graduate” at the end of the next semester. I willl take a course in VLSI system design as well as a managerial accounting course. Yes, I am backing down and taking a business course! I learned my lesson this semester with two engineering courses, it was just so intense. VLSI will be a great course, and I think that an accounting course would at least be useful knowledge.
