Abstract
When a logic synthesis of verified logic circuits is executed by a logic synthesis section, respective input variables, main terms, a minimum logical-OR form, and a cover condition of a logical expression are retained as reusable elements. In an optimization of a program code executed by a dedicated compiler, the program code is optimized by using the reusable elements. Thus, the processing time for the optimization of the program code can be shortened, and also, the amount of memory being used can be reduced.
