ABSTRACT:
A test method and structure is provided to determine the end count of a predetermined succession or series of binary numbers wherein one number and its relation in the succession to the end count number is known. The structure includes a circuit for generating a binary digit output and a device for storing at least a portion of the said one number which preferably is the penultimate number in a sequential series. A succession of binary numbers is generated as output of the circuit. the outputted numbers are compared to the portion of the stored number. A READY signal is outputted when the stored number compares with the outputted number. On a subsequent cycle, a control signal is generated when the generated number following the READY signal corresponds to the end count number. The inventor also contemplates programmable end count numbers.
