专利汇可以提供Semiconductor integrated circuit专利检索,专利查询,专利分析的服务。并且PURPOSE:To shorten an execution time for a computer largely in a CAD system for a layout by dividing and treating cell structure and an inter-cell wiring region and finally returning both to original states when preparing a master slice system IC. CONSTITUTION:A cell 1 is constituted while pairing a cell row 2 arranged in a row and an inter-cell wiring region 3 formed adjoined to the row 2, and one division array 7 is manufactured by disposing a plural pair of the cells 1. A division array wiring region 6 for wiring a plurality of the division arrays 7 is formed, and a wiring region 5 connecting the division arrays 7 and an I/O buffer group 4 is shaped, thus manufacturing a master slice system LSI. On the design, a signal wiring terminal to other arrays 7 or the buffer group 4 is mounted virtually to the array 7 as a terminal, which does not exist in the IC actually, and a signal terminal for the buffer group 4 is wired by using the virtual terminal. Divided states brought in this manner are returned to original states, and an execution time for a computer is reduced.,下面是Semiconductor integrated circuit专利的具体信息内容。
