Standard reference sources (Motorola's MECL System Design Handbook, for example1.7.1) give several formulas that relate to the propagation delay of a signal along a trace on a circuit board. These formulas have been combined and summarized in Figure 1.7a. The first part of the formula provides the basic propagation time under unloaded conditions. In that formula, a = 1 and b = 0 for Stripline configurations and a = .475 and b = .67 for Microstrip.
