Abstract
The use of the Oscillation Test Strategy to test Configurable Analog Blocks of Field Programmable Analog Arrays (FPAAs) has been proposed previously, solving the complex problem of test stimuli generation. An improvement to that technique is presented in this paper, using the resources of the FPAA to build an Output Response Analyzer. This new approach offers a full Built-In Self-Test scheme with no area overhead and requiring a low cost Automatic Test Equipment. Experiments show the efficiency of the approach in detecting parametric faults of the tested components.
