Abstract: Provided are a system for designing a semiconductor circuit and an operating method of the same. The system includes a working memory loading a clustering application for generating a cluster, based on instances respectively corresponding to cells of the semiconductor circuit, and loading a design tool for placing the cells. The clustering application, when an output terminal of a first instance is connected to a second instance and the number of instances connected to the output terminal of the first instance is one, classifies the first instance and the second instance into a candidate group pair. The clustering application, when all instances connected to an input terminal of the second instance are classified into the candidate group pair with the second instance, generates the cluster including the first instance and the second instance.

Abstract: The integrated circuit includes first and second vias, a first buffer configured to receive a signal transmitted from the first via, a second buffer configured to receive a signal transmitted from the second via, a first detour circuit configured to receive a signal transmitted through the second buffer, a second detour circuit configured to receive a signal transmitted through the first buffer, a first selector configured to selectively output one of the signal transmitted from the first via and a signal transmitted through the first detour circuit, and a second selector configured to selectively output one of the signal transmitted from the second via and a signal transmitted through the second detour circuit. Each of the first and second buffers and the first and second detour circuits transmits a signal in only one direction.
