TL;DR: Using the integral measure for characterizing time-domain signals, the minmax formulation of the static test problem is extended to the dynamic case and a sub-optimal solution strategy, similar to dynamic programming methods is used to construct the test waveforms.
Abstract: In this paper we present an approach to construct dynamic test signals for analog circuits. Using the integral measure for characterizing time-domain signals, we extend the minmax formulation of the static test problem to the dynamic case. A sub-optimal solution strategy, similar to dynamic programming methods is used to construct the test waveforms. The approach presented here may be used to construct input signals for an on-chip test scheme or for the selection of an external stimulus applied through an arbitrary waveform generator.

TL;DR: The structure of a current-based analog scan cell for analog and mixed-signal design-for-test is presented and techniques to apply this structure to continuous-time and sampled-data analog designs are described.
Abstract: This paper presents the structure of a current-based analog scan cell for analog and mixed-signal design-for-test. The cell uses current to represent the analog signal to be scanned and functions identically to a digital scan latch, except of course the scanned signal retains analog information. The concepts of scanning are explained using this structure, and some limitations, under experimental study at this time, are addressed. Techniques to apply this structure to continuous-time and sampled-data analog designs are described.
