Abstract
PURPOSE:To inspect a logical function in a small number of test cases by adding a memory contents reading means of a device to be tested and a test pattern generating means which produces the output value of each basic arithmetic element as well as a test input signal to a test device. CONSTITUTION:A test device 1 gives an input pattern to a software logical device 2 and fetches the final stage value of a logic circuit from an output part 23 via a signal input means 15. A memory contents reading means 14 reads the output value of each basic arithmetic element out of an arithmetic element output memory 25 and sends it to a comparison means 16. A variable address memory means 33 stores the address of the memory 25 and the means 14 reads the address of the memory 25 out of the means 33. Then the means 14 reads the output value of the basic arithmetic element out of the corresponding address of the memory 25. A comparison means 16 compares the test results given from both means 14 and 15 with a reference pattern received from a test case selection means 12. The result of this comparison is delivered to a result output means 17.
