// this is where the smarts of what type of trace subcircuit to generate will reside
// reference hspice98 - chapter21, pp 21-2: Selecting Wire Models
// choices for wire models:
// 1. no model
// 2. lumped models with RLC - simple R, shunt cap C, series inductor and resistor RL, series resistor and shunt cap RC
// 3. ideal - lossless transmission line
// 4. lossy transmission line
// decision based on :
// 1. source properties: rise time - trise, source resistance - Rsource
// 2. connector properties: characteristic impedance - Z0, time delay - TD (function of length/frequency)
// OR : equiv resistance - R, equiv inductance - L, equiv capacitance - C
// decision tree: Figure 21-1, Wire Model Selection Chart (wire_select.jpg)
// a) trise > 5TD (low frequency) --- use lumped model with RLC (criteria for R / RL / RC in wire_select.jpg)
// b) trise < 5TD (high frequence) --- use lossy or lossless transmission line
