Title: Device for equivalence inspection of sequential circuit, its method, and recording medium
Inventor: MUKOYAMA TERU
IPC: G06F17/50
Filed: 1998-08-11
Abstract: PROBLEM TO BE SOLVED: To shorten the time required for inspecting the equivalence of a sequential circuit based on the calculation of a bisecting decision diagram(BDD). SOLUTION: A sequential circuit 1 is connected to a sequential circuit 2, which are the objects of the equivalence inspection to obtain a sequential circuit C (S1-S3). The logical function of the sequential circuit C is obtained (S4) and the state transition BDD of the sequential circuit C which is divided into plural BDDs where the number of nodes is equal to or below a prescribed reference value is generated (S5). The initial state of the sequential circuit C is inputted (S6) and added to a state set S (S7). The state in the state set S is applied to the logical function of the sequential circuit C to obtain its output (S8). Unless the output is zero (S9), the plural successive states BDDs are generated from the plural divided state transition BDDs and the state set S (S11) and they are connected to obtain one successive state BDD (S12).  When the state N corresponding to one successive state BDD is included in the state set S (S13), the inspection result that the sequential circuits 1 and 2 are logically equivalent, is obtained (S14).
