The present invention provides a method and system for routing a group of scan chains to a group of processor resources in a semiconductor chip. The group of processor resources is arranged in rows or columns. The group of processor resources in each row or column is connected through a plurality of scan chains. The first processor resource in each row or column is connected to input scan-chain pins, and the last processor resource in each row or column is connected to output scan-chain pins. A test-pattern generator, generating test signals, sends the test signals to the group of processor resources by using the group of scan chains within the semiconductor chip. The responses of the processor resources corresponding to the test signals are analyzed to detect and locate any error in the manufacture of the semiconductor chip.
