Creating a Compact Power Supply and Monitoring System for the Occamy Chip (1-3S/B/2-3G)
- Type: Bachelor / Semester Thesis or Group Project
- Professor: Prof. Dr. L. Benini
We recently taped-out Occamy, (http://asic.ethz.ch/2022/Occamy.html, http://asic.ethz.ch/2022/Hedwig.html), a large-scale manycore chip featuring more than 400 cores. Occamy has a massive power consumption of over 100W (>130A at 0.8V) distributed over 11 power domains. Supplying the required power lets us face multiple challenges:
- We have to supply over 130A of current at very low voltages
- We have 11 independent supplies
- The supplies need to be turned on in a given sequence
- We want to monitor every supply closely
In this project, you will design and create a power supply PCB for Occamy. It will feature 11 power supplies controlled and monitored using I2C. The board should contain a facility to safely control and bring up the supplies in the proper sequence (uController or FPGA).
- 30% Design of the Power Supply board
- 30% Solder and test the board, program the device controlling the power-up sequence
- 40% Characterize your supply, improve the design if required and create a second version.
- Preferred: PCB design and soldering experience
- Preferred: Prior knowledge of FPGAs or uControllers
