Applying the Ideal Testing Framework To Hdl Programs

Abstract

This paper proposes a framework for testing behavioral model of sequential circuits implemented in Hardware Description Language (HDL). The concept of Ideal Testing is applied for achieving reliability and validity of both positive and negative testing. The HDL program is first modeled by a Finite State Machine (FSM) which is then converted to a Regular Expression (RE). This RE is used to construct test sequences. For positive testing, the original (fault-free) FSM model is used, while for negative testing its mutant model(s) are used to define requirements of ideal testing in conjunction with model-based and code-based mutation testing. A demonstrating example based on a real-life-like Traffic Light Controller (TLC) validates the proposed approach and analyzes its characteristic features. © ARCS 2018.
