Résumé
This paper proposes an original Design-For-Test (DFT) technique allowing the test of a complete set of converters embedded in a complex System-in-Package. The fundamental idea consists in implementing an additional circuitry allowing to interconnect the analogue ouputs of DAC's with the analogue inputs of ADC's. This globally results in an Analogue Network of interconnected Converters (ANC) that can be tested in a fully digital way. It is demonstrated that different configurations of the network can be described through a system of linearly independent equations. Solving the system of equations allows to determine the harmonic contribution of every converter in the network
