    摘要: An apparatus for producing test data used for detection of defects which occur in manufacturing functional blocks of a processor LSI is provided with a test pattern producing part for detecting a fault of the functional block at a block edge of the functional block, based on logic data of the functional block, with regard to one operation of the processor LSI which operates the functional block for the test data to be produced, the test pattern at the block edge of the functional block being such as to satisfy the conditions of an input signal to the block edge of the functional block when an instruction on the one operation is executed, and the conditions of an output signal from the block edge of the functional block being observable from the outside of the processor LSI when the instruction is executed. The apparatus also has an instruction sequence producing part for producing an instruction sequence in a machine language for the processor LSI by which an output from the block edge of the functional block becomes detectable at an external terminal of the processor LSI.

    摘要: The present invention relates to an LSI which performs a self test using its built-in test function according to a test program stored in an on-chip memory. An object of the present invention is to efficiently perform the self test in the case where branching to an address out of the address space of the on-chip memory occurs. A program counter 101 stores addresses of a memory 117 and an external memory. A test program counter 108 stores an address of the memory 117. In a test mode, a program counter switching section 109 performs control so that when an address of the memory 117 is detected in the program counter 101, the address value of the program counter 101 is selected, whereas when an address of the external memory is detected in the program counter 101, the address value of the test program counter 108 is selected. A signature compression circuit 110 signature-compresses and holds the output value of the program counter 101.
