When you consider all the different effects lumped under the term signal integrity, it seems like there is a neverending list of problems to keep track of: ground bounce, ringing, crosstalk, switching noise, rail collapse, delta I noise, capacitive coupling, reflections, discontinuities, impedance miss matches, lossy lines, terminations, branches, deterministic jitter, stubs, decoupling capacitors, loop inductance, via inductance, controlled impedance, time delay, skin depth, return current, layer transitions, differential impedance, collapse of the eye, common signal termination, differential signal termination, overshoot, intersymbol interference, ring back, etc.

It's a wonder anything ever works: signal integrity would be so much simpler without those pesky interconnects ruining our signals

Two commonly occurring PCB trace configurations are microstrip and stripline which can be represented by a chain of L C sections for lossless or RLCG for lossy lines (2).
