  • Method and apparatus for designing layout, and computer product
    Patent number: 7080338
    Abstract: A layout designing apparatus includes an input unit that receives an input of a frame having a boundary scan register, a placing unit that places an I/O macro to be connected to a signal terminal for propagating other signal than a test signal in an arbitrary I/O macro placement area of the frame input, a determining unit that determines whether a frame terminal at an arbitrary terminal position in the frame matches with at least one of a test terminal for propagating the test signal in the frame input and a signal terminal to be connected to the I/O macro placed, and a replacing unit that replaces, based on a result of determining by the determining unit, the I/O macro placed with either of a shared I/O macro and a test-only I/O macro.
