摘要
The present invention is directed to a method for generating a tech-library for a logic function. A logic function has many representations. For each representation, a circuit for realizing the representation is decomposed into a combination of instances. An instance is a component logic circuit of a general logic circuit. There are pre-created tech-libraries for the instances. For example, a pre-created tech-library is created by categorizing tech-descriptions for primitive physical circuits based on a negation index. Thus, tech-descriptions for a circuit for realizing a representation are calculated from a combination of elements of the pre-created tech-libraries. Each calculated tech-description is compared with each existing element of a tech-library for the logic function. When a calculated tech-description has at least one marked parameter better or smaller than that of all existing elements of the tech-library for the logic function, the calculated tech-description is added to the tech-library. When the number of elements in the tech-library is at least twice larger than a limit, the number is reduced.
