Abstract
A description is given of the impact of card wiring nets on signals generated by CMOS chips. Card nets driven by CMOS circuits are treated as transmission lines with lumped capacitances attached at points along the line, representing connections to other CMOS chips. Evaluation of overvoltage and undervoltage conditions, available noise margin, and reflection settling time is discussed. Allowable net length, effect of waveform rise and fall time, and of receiver loading on delays for typical net types is described
