It continues to boggle my mind that this guy chose to get fired over this paper, which is the dumbest paper I have read in a long time.
As an example, his paper reports *median* congestion! I literally laughed out loud when I saw that. I don't think a single other chip design paper in the world uses that metric, and for good reason.
For those of you who don't know chip design, congestion is a measure of how many wires will need to go in the same place when you do routing for the chip. When wires overlap, they have to go above / below each other, and your chip only has so many layers. If congestion is too high, it can simply be impossible to make the chip.
Congestion is therefore all about the extreme values. Why in the world would you report median congestion, then? Median ignores extreme values, which are the only ones you care about!
I even checked the paper he cites as being prior work that uses median congestion, to see who else did something so stupid, and... it doesn't! It uses average, which makes way more sense. I mean, you really care about the max, but at least average is sensitive to extremes.
I could go on, but the TLDR is, his paper is hot garbage, and I cannot say I am surprised Google didn't want its name associated with it.
