• Attended VtR meeting
• Interested in work on placement constraints in VtR, especially constraining within a rectangle
• Did more research into PR in arch-defs or VtR, think they can be complementary (for different use cases)
• VtR placement constraint works gets you most of the way there for PR based in VtR
• Leaning towards PR in arch-defs out of optimizing for speed after "overlay" generation and allowing much smaller rr_graphs for loading on board
• Still working on trying to run custom bitstreams on the zynq with PS code generated by Vitis/SDSoC
• Will help with testing real world PR later on
• Some progress loading from SD card using https://github.com/antmicro/zynq-mkbootimage
• Fixed mkbootimage bug, will submit pull request soon
