Abstract
IC 5 for exclusive use in wiring control has been used in conventional emtion system which is difficult in coping with various types of logic verification and results in high cost. An emulation system according to the invention comprises: a digital input terminal section 8 to which a digital signal is inputted; a plurality of field programmable gate arrays 1 to 4 for verifying logic of the inputted signal; a digital output terminal section 9 for outputting a signal of which logic has been verified; a wiring control selector section 7 which is connected to the digital input terminal section 8 and to the digital output terminal section 9; and an analog universal region 6 which is connected to said wiring control selector section 7; thereby carrying out wiring control between the wiring control selector section and the plurality of field programmable gate arrays, and wiring control among the plurality of field programmable gate arrays.
