Patent attributes
A semiconductor integrated circuit device includes a column of first logic circuit cells arranged along a first side of a chip and a column of second logic circuit cells arranged along a second side orthogonal to the first side. At a corner part where the first side crosses the second side, a first test logic circuit cell is arranged to have its long side faced with a side of a cell at an end portion of the column of the first logic circuit cells and a second logic circuit cell is arranged to have its long side faced with a side of a cell at an end portion of the column of the second logic circuit cells. The first and the second test logic circuit cells are arranged so a that planar shapes thereof are symmetrical (mirror symmetrical) to each other with respect to a virtual line intermediate between the oblique sides arranged opposite to each other.
