I should probably clarify. What I meant to say is that they don't really teach high-frequency analog design in school. We covered the theoretical aspects, like impedance matching and reflection, but there's a long way between knowing those things and being able to reason with them when designing a chip.

Well if you understood the fundamentals it's actually not that far to being able to design a board. Designing a chip is a whole other matter but can also be quite easy if you are comfortable with FPGAs and using IP cores. I'd say there's about a 0% chance of you having your own fab so the ASIC firm you hire will usually help you synthesize the high level language design to silicon (for a price). Once you're comfortable with your routing tool, check out the following links. This is the material I use as a refresher when jumping back into high speed digital design: http://www.ti.com/lit/an/scaa082/scaa082.pdf http://www.ti.com/lit/an/scaa082/scaa082.pdf <-- Check out page 7, has a great diagram for what happens with reflections http://www.freescale.com/files/32bit/doc/app_note/AN2536.pdf http://www.freescale.com/files/32bit/doc/app_note/AN2536.pdf http://www.altera.com/literature/hb/stx2/stx2_sii52012.pdf http://www.altera.com/literature/hb/stx2/stx2_sii52012.pdf

  I should mention that I'm a computer engineering major and not a EE major, so I haven't taken some of the more advanced physics classes like solid state physics or electromagnetics. Are there any resources you would recommend for getting more of the theoretical background on those topics?

    I've tried to learn the physics behind EE but my brain has been shot too many times by primary through secondary education. As a CS major you can dive in depth into the PCI/DDR standards and they will teach you alot about the signals. Combine it with a application note on DDR routing and you'll get the big picture.
