* - Key Global Variables: *
-
* - IntImped (ohms) = Intrinsic impedance of a line (no dist. cap.) *
- EffImped (ohms) = Effective impedance after dist. cap. considered. *
- IntProp (ns/ft)= Intrinsic prop. delay of a line (no dist. cap.) *
- EffProp (ns/ft)= Effective prop. delay after dist. cap. considered. *
- IntCap (pf/in) = Intrinsic capacitance of the line. *
- DistCap (pf/in) = Extra capacitance distributed along a line. *
- IntInd (nH/in) = Intrinsic inductance of the line. *
- IntRes (ohms/in)= Intrinsic resistance of the line. *
