                **** MICROELECTRONICS TECHNOLOGY BULLETIN ****
                                                             November 11, 1992


Technology:         BNR's DFT Tools
Developed By:       Northern Telecom
Release Date:       November 10, 1992
ID Code:            SE0158
Status:             Supported

Description:        The BNR  Scan  Design approach for the purpose of automatic
                    generation of test  that  guarantees  high structural fault
                    coverage.  The test  generated  by the Scan Software checks
                    each element in the circuit  to  verify  that  the  element
                    operates correctly.  

                    Key points:
                    -   Storage elements  can be tested by  shifting  a  simple
                        pattern through the Scan chain and observing.

                    -   Test    vectors   for  combinational  circuits  can  be
                        generated automatically,  and combinational logic tests
                        can be applied  by  shifting  inputs and outputs in and
                        out of the Scan chain.
