CA 2092333

Control of the self-testing of a plurality of elements (12 1 -12 m), each having a Built-In, Self-Test (BIST) capability, and arranged in one or more groups (14 1 -14 n), is carried out by a network (16) of one or more standard BIST resource interface controllers (SBRICs 18 1 - 18 n). Each SBRIC in the network controls the self-testing of the elements in a separate one of the groups in sequence by broadcasting a test command to the elements in parallel which, in response, generate test signatures stored by the SBRIC. The SBRICs in the network are coupled in series in daisy chain fashion to enable the test signatures stored by the SBRICs to be concatenated for easy retrieval by shifting out the test signatures therefrom, using a technique such as boundary scan.

L'autovérification d'une pluralité d'éléments (12 1-12 m) dotés chacun d'une fonction d'autovérification (BIST), ces éléments étant groupés en un ou plusieurs groupes (14 1-14 n), est commandée par un réseau (16) constitué d'un ou plusieurs contrôleurs d'interface de ressource BIST standard (SBRIC 18 1-18 n). Chaque SBRIC du réseau contrôle l'autovérification des éléments à tour de rôle dans un groupe particulier en transmettant une instruction de vérification en parallèle aux éléments qui, en réponse, produisent des signatures de vérification qui sont stockées dans le SBRIC. Les SBRIC du réseau sont couplés en série par une connexion en guirlande pour que les signatures de vérification stockées par eux puissent être groupées afin d'en faciliter l'extraction, au moyen d'un test périphérique par exemple.
