Circuit design assisting apparatus, method, and program

摘要

A circuit design assisting apparatus for assisting a layout tool in designing an integrated circuit that includes a circuit module having plural cells achieving a prescribed function. A cell connection information acquiring device is provided to acquire cell connection information that specifies connection counterparts to the plural cells and is used when auto layout is executed by the layout tool. A terminal designating device is provided to designate a terminal of the circuit module. A terminal connection information generation device is provided to generate terminal connection information that specifies connecting counterparts to the terminal. A buffer circuit addition determining device is provided to determine one of if a buffer circuit is additionally connected between the terminal and the counterpart and if the buffer circuit already connected to the terminal is replaced in accordance with the terminal connection information.
