Abstract
PURPOSE:To shorten the time needed for production of a logic circuit by performing the open/close control between the input and output terminals of each programmable logic device PLD via a gate when plural PLDs are used for production of a logic circuit simulator. CONSTITUTION:When a logic circuit simulator is produced by PLD1 and 2, the proper connection is secured among input and output pins 1-2-1, 1-2-2, 1-1-1, 1-1-2, 2-2-1, 2-2-2, 2-1-1 and 2-1-2 of both PLD1 and 2 via gates. Thus the due output and input pins are connected to each other with due gates turned on. Thus it is possible to omit the time needed for reconnection of terminals carried out via a print circuit, etc., for each production of a logic circuit simulator.
