Abstract

L’invention concerne un procédé et un système de test d’un circuit intégré comportant des portes logiques, des bascules logiques et une mémoire réinscriptible, le circuit intégré comportant une horloge interne, le circuit intégré étant configurable dans un mode de fonctionnement dit mode chaîne de balayage. Selon l’invention : - on met le circuit intégré dans le mode chaîne de balayage, - on isole avec des moyens d’isolement la mémoire réinscriptible des portes logiques des bascules logiques, - on cadence (Clk) les moyens d’isolement par une horloge externe, - on varie la périodicité de l’horloge externe, - on lit (300) le contenu de la mémoire réinscriptible et on le compare à une valeur, - on détermine (300) le temps d’accès de la mémoire réinscriptible en fonction de la comparaison. Fig. 3The invention relates to a method and a system for testing an integrated circuit comprising logic gates, logic flip-flops and a rewritable memory, the integrated circuit comprising an internal clock, the integrated circuit being configurable in an operating mode called chain mode sweep. According to the invention: - the integrated circuit is placed in scan chain mode, - the rewritable memory of the logic gates of the logic flip-flops is isolated with isolation means, - the isolation means are clocked (Clk) by a external clock, - the periodicity of the external clock is varied, - the content of the rewritable memory is read (300) and it is compared with a value, - the access time of the rewritable memory is determined (300) by comparison function.
