Wasn't there an GA FPGA design to distinguish two tones that was so weird and specific not only did it use capacitance for part on its work but literally couldn't work on another chip of the same model?
- robotresearcher 2y agoYes. The work of Adrian Thompson at the University of Sussex. https://scholar.google.com/citations?user=5UOUU7MAAAAJ&hl=en https://scholar.google.com/citations?user=5UOUU7MAAAAJ&hl=en
- isoprophlex 2y agoYes, indeed, although the exact reference escapes me for the moment. What I found absolutely amazing when reading about this, is that this is exactly how I always imagined things in nature evolving. Biology is mostly just messy physics where everything happens at the same time across many levels of time and space, and a complex system that has evolved naturally appears to always contain these super weird specific cross-functional hacks that somehow end up working super well towards some goal

- actionfromafar 2y agoI think it was that or a similar test where it would not even run on another part, just the single part it was evolved on.
- hinkley 2y agoAs I recall it didn’t even work from day to day due to variance in the power supply triggered by variance in the power grid. They had to redo the experiment on simulated chips.
