In a preparation for a beverage for dogs in a liquid or a solid form for dissolution in water, there are included in the beverage at least flavor carriers, minerals and proteins and other constituents. With this configuration, a minimum operating power supply voltage may be reduced in an electronic circuit, and the power supply voltage may be used with efficiency. The design layout data or the OPC processing is changed such that when a pattern is formed under the worst condition based on the changed design layout data or the changed OPC processing a number of the risk points or a risk degree of the risk points of the pattern is smaller than the simulation result.
