PROBLEM TO BE SOLVED: To provide a technology enabling logical verification corresponding to different requirements of specification such as pin arrangement having no restriction on a system board subjected to logical verification or high rate signal transmission. SOLUTION: The logical module comprises a plurality of programmable logical elements, switching elements and connectors mounted on one or both sides of a substrate wherein the connectors on the opposite sides of the substrate have the same shape so that they can be mounted upside down. The ratio of the number of I/O connections from the connectors to the logical elements and switching elements configures a different architecture between the connectors on the surface and rear. When the connectors on the surface and rear are used separately, logical verification can be effected in correspondence with different requirements of specification, e.g. pin arrangement having no restriction on a system board or high rate signal transmission. |
