The 16th IEEE International High Level Design Validation and Test Workshop (HLDVT) advances research in validation and test methodologies for integrated circuits and systems. The workshop focuses on addressing the current bottlenecks in validation and test of complex and heterogeneous systems by both employing high-level specifications (such as register transfer level, behavioral and system-level models) and developing associated tools, techniques and methodologies to enable drastic reduction in overall design, validation and test effort. The workshop provides a forum for leaders in both industry and academia to advance the means for validating, debugging, synthesizing, and testing complex systems in a way that opens new avenues to overcome current validation and test challenges.
