Abstract
PURPOSE: To realize an electric and high-speed test for the input unit by delivering the simulation sequence data for keyboard input in sequence onto the keyboard interface based on the interface rule of the tested system.
CONSTITUTION: When the data equivalent to one block is read into block buffer 12 from input unit 11 among the simulation sequence data for keyboard input which is decided previously, address counter 13 is set to the initial value. And based on the contents of counter 13, selector 14 selects one letter in buffer 12 to then set it to 1- character buffer 15. After this, the signal to set flip-flop 16 for a fixed time is delivered from control part 18 to form the strobe signal, and thus the contents of buffer 15 are sent to the system. Then counter 13 receives addition of +1, and the above operation is repeated until the finish is detected by decoder 17.
