PURPOSE:To facilitate communication between units by simple constitution and realize a hardware logic simulator by providing a communication switch between units. CONSTITUTION:A communication switch 30 is provided between units 11, 13 of a hardware logic simulator, and the units 11, 13 are controlled by a controller. Command C2 from the controller is applied to the units 11, 13 and pin number OPN that outputs and stored in the output memory 132 of the unit 13 and its new value NV are selected in a set by a counter 133. The number OPN of the output is sent to a selected vector generator 302 of the switch 30, and the new value NV is sent to a selector 301. The selected vector S13 is applied to the selector 301 the number OPN inputted by the generator 302 as an address, and data corresponding to the vector S13 is sent to a data line D, and a writing control signal is sent to a control line W. Simulation is performed by controlling an event memory 112 of the unit 11 by the number turned on the unit 13. |
