The present invention relates to a method for the parallel production of circuitry and software for a customised integrated circuit, primarily an ASIC- type circuit, mounted on a printed board assembly or circuit board (300). The method comprises connecting a programmable logic circuit (345) which replaces the customised integrated circuit during the development phase. The programmable logic circuit (345) is mounted on the secondary side of the circuit board (300) and its connections are passed through (330) the circuit board (300) to the circuits (305, 310) and components (320, 325) to which the customised integrated circuit will be connected. The invention also relates to a method and to a device respectively for developing and verifying customised integrated circuits per se. In this case, a programmable logic circuit designed as a logic analyser is mounted on the secondary side of the circuit board and connected to the customised integrated circuit through the board.

L'invention concerne un procédé permettant de produire parallèlement des circuits et un logiciel destinés à un circuit intégré personnalisé, de préférence, un circuit de type ASIC, monté sur un ensemble carte imprimée ou une carte à circuits imprimés (300). Le procédé consiste à connecter un circuit logique programmable (345) qui remplace le circuit intégré personnalisé pendant la phase de développement. Ce circuit logique programmable (345) est monté du côté secondaire de la carte à circuits imprimés (300) et ses connexions traversent (330) la carte imprimée (300) pour être reliées aux circuits (305, 310) et composants (320, 325) auxquels le circuit intégré personnalisé doit être connecté. L'invention concerne également un procédé et un dispositif permettant de développer et de vérifier les circuits intégrés connus en soi. En l'occurrence, un circuit logique programmable conçu comme analyseur logique est monté du côté secondaire de la carte à circuits imprimés et connectée au circuit intégré personnalisé à travers la carte.
