Title (EN) LSI CIRCUIT LOGIC STRUCTURE INCLUDING DATA COMPRESSION CIRCUITRY
(FR) STRUCTURE LOGIQUE DE CIRCUIT LSI COMPRENANT UN RESEAU DE CIRCUITS DE COMPRESSION DE DONNEES
Abstract: front page image
(EN)A logic structure for an LSI digital circuit (fig. 1) includes data compression circuitry (fig. 2) for deriving a signature word from the data on a multiplicity of internal nodes (113, 114, 115, 116, 117, 118) which are directly accessible from the terminals (104) of the circuit. The signature word provides error information concerning the data on the internal nodes which are not otherwise available for testing purposes. The addition of data compression circuitry facilitates the testing of LSI digital circuits and can be complemented with minimal overhead chip area.
(FR)Une structure logique pour un circuit digital LSI (integration a grande echelle) (Fig. 1) comprend un reseau de circuits de compression de donnees (Fig. 2) pour deriver un mot de signature des donnees sur une multitude de noeuds internes (113, 114, 115, 116, 117, 118) qui sont directement accessibles a partir des terminaux (104) du circuit. Le mot de signature fournit une information d"erreurs concernant les donnees sur les noeuds internes qui ne sont pas autrement disponibles a des fins de controle. L"addition d"un reseau de circuits de compression de donnees facilite le controle des circuits digitaux LSI et peut etre complete avec une surface minimum de micro-plaquettes de servitude.
