2. Goal

3. The goal is to develop an ATPG program with fast run time, few generated patterns and high fault coverage under the given multi‐core computing environment. The designed ATPG program should have the ability to handle single stuck‐at faults in combinational logic circuits. An evaluation set consist of several benchmarks is provided for verifying your program. A benchmark is a combinational logic circuit in the form of a Verilog gate‐level netlist.

4. Introduction

5. ATPG (acronym for both Automatic Test Pattern Generation and Automatic Test Pattern Generator) is an electronic design automation method/technology

6. Program structure

7. We use the 2‐bit adder as an example to illustrate briefly the operation of pattern generation. First, the gate level netlist is read to construct the structure of design . Second, find all single stuck‐at faults in this design and generate the fault list. Third, collapse the faults. The collapsed faults are used to calculate the fault coverage. Forth, pick up the fault one by one from the fault list to generate test pattern by running test algorithm.
