ABSTRACT:
On the basis of a period of a timing signal, a signal propagation delay in a device unit, signal propagation delay in the timing signal bus and the data bus, and a setup time of another device unit or a device connected to the data bus, a timing at which noise caused by active connection of the first device to the data bus is propagated to the other device unit or the device is computed in a step of noise propagation computing, and on the basis of the timing computed in the step of noise propagation computing, a connection timing at which the first device unit is connected to the data bus. With thes two steps, a noise caused by active connection of a device unit does not affect other device units and devices connected to the same data bus.
