In a semiconductor chip, a second power source pad, to which a ground potential is applied, is arranged adjacent to a first power source pad, to which a power source potential is applied, signal pads are arranged adjacent to the second power source pad by the number corresponding to a size of an external part such as a bypass capacitor inserted between power source terminals in an IC chip, and further, a third power source pad, to which the ground potential is applied, is arranged adjacent to the signal pad. The second power source pad or the third power source pad is selected according to the size of the external part, and then, is connected to a lead terminal, to which the ground potential is applied, in an IC chip, thereby providing a power source terminal, to which the ground potential is applied.

An apparatus for testing an anti-lock brake system has rolls and device for detecting rotational changes of the rolls. The test is performed by running a vehicle having mounted thereon the anti-lock brake system while wheels of the vehicle are placed on the rolls, actuating the anti-lock brake system when a predetermined speed has been attained, and judging operating conditions of the anti-lock brake system from rotational changes of the rolls at the time of braking. In the apparatus, the friction coefficient of each of the rolls is set to such a value that a frictional force to act between each of the rolls and each of the wheels at the time of braking exceeds an inertia force of each of the rolls. Also the inertia weight of each of the rolls is set to such a value that deceleration of each of the wheels at the time of braking can be increased to a predetermined level which is required to start an anti-lock control and that each of the wheels does not stop before the completion of a first braking pressure reduction by the anti-lock control.
