摘要:
As a basic connection information determined on the basis of a basic information determined in advance between logic elements by paying attention to the flow of data, the present invention includes a structure for transferring data from one data element to another data element, a structure for transferring data from one data element to a plurality of data elements and a structure for transferring data from a plurality of data elements to one data element, decides the sequence of unidimensional placement of sets of elements as the object of the flow of data inside a logic circuit on the basis of these structures, and automatically and quickly determine the initial placement positions of the sets of elements from the sequence thus decided.
