Abstract

An output of an element under test is captured and stored, through a multiplexer, in a capture register. At a clock edge (either rising or falling edge) the element under test catches the “edge” and “strobes” the output. The multiplexer is strobed, and the delay and duty cycle are measured. Both the rising and falling edge are used as the timer.
