ELECTRONIC CIRCUIT USING PROGRAMMABLE LOGIC CIRCUIT

摘要

PURPOSE:To provide an electronic circuit which uses a PLD circuit that can easily change the electronic circuit without soldering a jumper wire when the electronic circuit is debugged. CONSTITUTION:A jumper pin 13 having plural pairs of pins is placed between a PLD 11 and a PLD 12, and the wiring patterns connect the output terminals of both PLD 11 and 12 to the pairs of pins of the pin 13. Then the pins of the pin 13 are used as test pins when an electronic circuit is debugged, and at the same time a jumper socket 32 is put into those paires of pins for connection between the PLD 11 and 12.
