چکیده

We present a novel test-per-clock BIST method for combinational or full-scan circuits. Our task is to design a combinational circuit, namely the output decoder, transforming the pseudorandom LFSR code words into the required test patterns pre-generated by some ATPG tool. The process is based on finding the coverage of the ones in the test vectors and the subsequent generation of implicants that correspond to this coverage. The implicants are derived from the LFSR code words. The design of the output decoder is taken as a general combinatorial problem and it can be exploited in other areas of logic design too.

An algorithmic approach to optimizing fault coverage for BIST logic synthesis

Most approaches to the synthesis of built-in self test (BIST) circuitry use a manual choose-and-evaluate approach, where a particular BIST generator is chosen and then evaluated by faultsimulating the design with the vectors that the chosen generator generates. We develop an algorithmic synthesis-during-test approach in this paper, wherein the tasks of synthesizing the BIST logic and directed t...

A new approach to built-in self-testable datapath synthesis based on integer linear programming

The focus of high-level built-in self-test (BIST) synthesis is register assignment, which involves system register assignment, BIST register assignment, and interconnection assignment. To reduce the complexity involved in the assignment process, existing high-level BIST synthesis methods decouple the three tasks and perform the tasks sequentially at the cost of global optimality. They also try ...

Minimization of Boolean Functions

This thesis presents two new methods of test-per-clock BIST design for combinational circuits. One of them is based on a transformation of the PRPG code words into test patterns generated by an ATPG tool. This transformation is done by a combinational circuit. For a design of such a circuit two major tasks have to be solved: first, the proper matching between the PRPG code words and the test pa...

On Using Machine Learning for Logic BIST

This paper presents a new approach for designing test sequences to be generated on–chip. The proposed technique is based on machine learning, and provides a way to generate efficient patterns to be used during BIST test pattern generation. The main idea is that test patterns detecting random pattern resistant faults are not embedded in a pseudo–random sequence as in existing techniques, but rat...

Obtaining High Fault Coverage with Circular BIST Via State Skipping

Despite all of the advantages that circular BIST ofsers compared to conventional BIST approaches in terms of low area overhead, simple control logic, and easy insertion, it has seen limited use because it does not reliably provide high fault coverage. This paper presents a systematic approach for achieving high fault coverage with circular BIST. The basic idea is to add a small amount of logic ...
