Cool! Out of curiosity, do these debugging tools keep pace with the recent process shrinks? I would imagine it's really hard to connect a logic probe to, for example, a processor built on TSMC's 7nm process.
- sounds 7y agoThe metal layer interconnects usually are _not_ that small. I can't share the exact specs for TSMC's 7nm process but here's an example that should give you some idea: https://web.stanford.edu/class/ee311/NOTES/Interconnect%20Scaling.pdf https://web.stanford.edu/class/ee311/NOTES/Interconnect%20Sc...
- baybal2 7y agoGate size on 7nm processes is still 30nm, and even the lowermost M0 metal is way, way bigger. Even if doing so requires destroying, and reconstructing some tracks around the probe, 7nm shouldn't be much different from how it was done back a decade ago.
