Much like the famous American comedian and actor Rodney Dangerfield, printed circuit boards (PCBs) just "don't get no respect!"
When I was a young lad just starting out in electronics as a hobby, pretty much the only circuit boards I personally got to work with were those that came with do-it-yourself kits. These little scamps were single-sided (you had to use jumper wires where traces wanted to cross), and the tracks were huge by today's standards -- signal tracks were probably a tad under 1/20" wide; power traces were anything up to 3/16" wide; and the ground trace ("plane" is too posh a word) did its best to fill in the gaps. Also, everything regarding the layout of the copper was generally hand-drawn and much more "organic" in those days.
David Patterson, known for his pioneering research that led to RAID, clusters and more, is part of a team at UC Berkeley that recently made its RISC-V processor architecture an open source hardware offering. We talk with Patterson and one of his colleagues behind the effort about the opportunities they see, what new kinds of designs they hope to enable and what it means for today’s commercial processor giants such as Intel, ARM and Imagination Technologies.
