Abstract
A method of diagnosing a circuit layout and a computer system for performing the method. First, a layout arranging rule is defined in a second file, and a circuit layout is defined in a first file. A diagnosing program compares the first file and the second file and checks whether the circuit layout violates the layout arranging rule. In addition, the diagnosing program searches the first file to determine if any groups of power test pads have a total number of power test pads which is less than a safety value, to indicate if any additional power test pads are required for any particular group. The diagnosing program also determines which test pads have an interval less than a safety distance, to indicate if any intervals of the test pads should be amended. The computer system can rapidly and exactly determine any problems in the arrangement of the test pads in the circuit layout, so as to save manpower and time.
