Scanners for visualizing activity of analog VLSI circuitry

Abstract

This paper tutorially describes mixed digital-analog serial multiplexers (scanners) that we use to visualize the activity of one- and two-dimensional arrays of analog VLSI elements. These scanners range from simple one-dimensional devices designed to scan a one-dimensional array onto an oscilloscope, to complete video scanners with integrated sync and blank computation and on-chip video amplifiers. We discuss practical details of design and performance, and we give a source for example scanner layout.
