A method of detecting moisture or wetness which enables determination as to whether or not precision instruments or industrial products have undergone improper conditions, is described, which comprises: (i) use of a composite material which contains at least one water-soluble decoloring agent and at least one methine dye whose color disappears upon reaction with the decoloring agent in a state that the decoloring agent and the dye are spatially isolated from each other, and (ii) detection of a history of contact with moisture or water by disappearance of color from the composite material.

To prevent obstacles to wiring caused when wiring from other nets pass through the vicinity of a terminal, and moreover, to carry out automatic wiring having shorter wiring length and increased wiring completion rate, when calculating wiring costs of a wiring route of a net, for unwired terminals belonging to other nets, wiring route cost values for the net to be wired are variably assigned depending on distance from these terminals. In other words, in the present invention, cost values are established such that the cost weighting decreases with distance from unwired terminals of other nets. Seen from a different viewpoint, in the present invention, cost values are established such that cost increases for wiring routes passing within a prescribed range of an unwired terminal of another net. Incorporation of the above-described set cost value into the calculation of wiring costs enables automatic wiring that reduces cost, shortens wiring length, and prevents occurrence of unwired nets.

A method for designing an interconnection route in an LSI includes steps of finding a minimum-cost path among possible paths for a current net, the possible paths overlapping with existing nets routed before the current net. A unit cost assigned to a grid for scoring possible paths includes a length cost and a rip-up and reroute cost for ripping-up and rerouting the existing nets overlapping with the current net in the grid. The rip-up and reroute cost is not scored, however, when the existing nets also overlaps with the current net in another grid so far routed. The route will be possibly selected in a path overlapping with a several wire segments of a single existing net rather than overlapping with a single segment of each of a plurality of existing nets. Number of rip-up and reroute procedure is reduced so that the speed of routing process is improved, providing a lower cost for routing an interconnection route in a computer.
