Abstract
PURPOSE:To generate test patterns of two systems associatively by controlling a sequence generator which has a register and a program counter receiving data from the register selectively by an instruction memory of SQG. CONSTITUTION:A 1st sequence generator 10 generates address information for access to a 1st or 2nd pattern memory 1 or 2 according to the contents of an instruction memory 11. Further, the value of the program counter 26 is updated according to the contents of the instruction memory 11 and a 2nd sequence generator 20 generates address information on the 1st or 2nd pattern memory 1 or 2. Then a 1st selecting circuit 17 or 2nd selecting circuit 18 receives and selects the address information sent out of the 1st sequence generator 10 or address information sent out of the 2nd sequence generator 20 and sends it out to the 1st pattern memory 1st or 2nd pattern memory 2.
