Abstract

UN SISTEMA (10) PARA PROBAR UNO O MAS TABLEROS DE CIRCUITOS (121-12N) CADA UNO DE LOS CUALES CONTIENE AL MENOS UNA CADENA DE CELDAS DE EXPLORACION DE MARGENES (141-14N) QUE INCLUYE UN ORDENADOR CENTRAL DE PRUEBA Y DIAGNOSTICO DEL SISTEMA (16) PARA GESTIONAR LA PRUEBA GENERAL DEL SISTEMA FORMADO POR LOS TABLEROS DE CIRCUITOS. UNA MAQUINA DE EXPLORACION DE MARGENES VIRTUAL (BVM) (17) SE ACTIVA PARA RECIBIR UN COMANDO DE INICIACION DE UNA PRUEBA PROCEDENTE DEL ORDENADOR CENTRAL DE PRUEBA UN DIAGNOSTICO DEL SISTEMA INDEPENDIENTE DEL NUMERO O DE LA NATURALEZA DE LOS TABLEROS A PROBAR. EN RESPUESTA AL COMANDO DE PRUEBA, LA BVM (17) HACE QUE CADA TABLERO DE CIRCUITOS EJECUTE UN PROGRAMA DE PRUEBA (23) ESPECIFICO AL MISMO PARA DETERMINAR LOS ERRORES, SI LOS HUBIERA, DEL TABLERO. LOS ERRORES DE CADA TABLERO SE VUELVEN A ENVIAR A LA BVM (17) QUE A SU VEZ INTERPRETA LOS ERRORES PARA PROPORCIONAR INFORMACION SOBRE LA PRUEBA, INDICATIVA DEL FUNCIONAMIENTO DE LOS TABLEROS, QUE SE ENVIA ENTONCES AL ORDENADOR CENTRAL DE PRUEBA Y DIAGNOSTICO DEL SISTEMA (16).
