1. An automated synthesis apparatus comprising: a condition vector generating unit that creates a condition vector with respect to a node in a behavioral description; and a scheduling unit; wherein said condition vector generating unit generates a generalized condition vector (GCV) that includes valid bits which are set in consecutive components of a portion of the vector in a case where, with respect to one operation node in the behavioral description, an outer conditional operation to said one operation node is unresolved and an inner conditional operation to said one operation node is resolved, the valid bits being bits at positions where components of an extended condition vector (ECV) of the inner side resolved conditional operation are 1's; and said scheduling unit performs scheduling, which includes processing for allocating an operation to a cycle, based upon the generalized condition vector (GCV) given to an operation node of a control/data flow graph corresponding to the behavioral description.
