The following table, generated partially using the included Tcl script names
stat.tcl, shows the relative complexity of the benchmarks in terms of
component counts.  The column headings are:
	i for current sources
	n for nodes (total number, does not take shorts into account)
	r for resistors (includes shorts)
	s for shorts (zero values resistors and voltage sources)
	v for voltage sources (includes shorts)
	l for the number of metal levels included in the circuit
