Abstract
PURPOSE:To simplify a testing by supplying the data for testing in a history memory through a switching means to a prescribed logical block and storing the output directly as the data for inspection or to the history memory as the output data for the inspection through a rear step logical block. CONSTITUTION:In a logical device 1 composed of plural logical blocks 21-2n and a history mechanism 3, the output data and the data for testing for the machine cycle of at least a special block of the blocks 21-2n are stored in a history memory 4 of the mechanism 3, and by a switching means 5 provided at the front step of a prescribed block 2i, the data from a front step block 2i-1 and the data for testing from the memory 4 are switched and supplied. At the time of testing, the data for testing are supplied to a block 2i by the means 5, the output data are stored into the memory 4 as the output data for inspection or the output data are stored through the prescribed number of the rear step logical blocks 2i+1 into the memory 4 as the output data for inspection of the block 2i and the block 2i+1.
