> Today I still work in hardware, but mostly with digital circuits. While my analog knowledge has decayed over the last decade, that project and it's success gives me great confidence any time I have to deal with the domain.

Do you think about the analog qualities of your traces when laying things out? If so then the course was well taken.

In my observations I've found that too many digital engineers assume a differential pair will save them without actually fixing the impedance and parasitic issues. Particularly as the timings of things become so much more precise analog is so important. People forget that a digital circuit is just an analog one under the covers.






The way my teacher put it: “High speed digital electronics is just analog with a rise time.”
