Test circuits for integrated circuit counterfeit detection

Described herein are various technologies pertaining to identifying counterfeit integrated circuits (ICs) by way of allowing the origin of fabrication to be verified. An IC comprises a main circuit and a test circuit that is independent of the main circuit. The test circuit comprises at least one ring oscillator (RO) signal that, when energized, is configured to output a signal that is indicative of a semiconductor fabrication facility where the IC was manufactured.

Network testbed creation and validation

Embodiments of network testbed creation and validation processes are described herein. A "network testbed" is a replicated environment used to validate a target network or an aspect of its design. Embodiments describe a network testbed that comprises virtual testbed nodes executed via a plurality of physical infrastructure nodes. The virtual testbed nodes utilize these hardware resources as a network "fabric," thereby enabling rapid configuration and reconfiguration of the virtual testbed nodes without requiring reconfiguration of the physical infrastructure nodes. Thus, in contrast to prior art solutions which require a tester manually build an emulated environment of physically connected network devices, embodiments receive or derive a target network description and build out a replica of this description using virtual testbed nodes executed via the physical infrastructure nodes. This process allows for the creation of very large (e.g., tens of thousands of network elements) and/or very topologically complex test networks.
