A New User-Friendly ATPG Platform for Digital Circuits

The paper presents a new graphical platform for automatic test patterns generation and fault simulation for digital circuits. The platform integrates two existing academic tools for test pattern generation and fault simulation: ATALANTA and HOPE. Both tools use a specific format "bench" for circuit description which is not suitable in connection to professional CAD tools. Therefore, the platform has been extended by a new translator for mapping a VHDL digital circuit model to the format "bench". The platform contains also a separate random test patterns generator linked to the fault simulator HOPE and generation of test pairs for delay faults using the transition fault model. The new automatic test pattern generation platform provides a user-friendly environment suitable for education.
