Abstract: Techniques for assigning scenario-based tests to test assets are described. In an example, a scenario-based test operable to test a key performance indicator (KPI) of a System Under Test (SUT), a component behavior exhibited by a first component of the SUT, and a scenario characteristic are received. Based on the component behavior and the scenario characteristic, a first plurality of behavior models associated with the component behavior are identified. Based on the scenario characteristic a characteristic value is extracted from the scenario-based test. Each behavior model of the first plurality of behavior models is executed using the characteristic value to generate a first plurality of predicted behavior outcomes. Based on the first plurality of predicted behavior outcomes, a first test asset type from a plurality of test asset types is selected and the scenario-based test is transmitted to a test asset of the first test asset type.

Abstract: Global optimization and verification of cyber-physical systems using graphical floating point math functionality on a heterogeneous hardware system (HHS). A program includes floating point implementations of a control program (CP), model of a physical system (MPS), objective function, requirements verification program (RVP), and/or global optimizer. A simulation simulates HHS implementation of the program using co-simulation with a trusted model, including simulating behavior and timing of distributed execution of the program on the HHS, and may verify the HHS implementation using the RVP. The HHS is configured to execute the CP and MPS concurrently in a distributed manner. After deploying the program to the HHS, the HHS is configured to globally optimize (improve) the CP and MPS executing concurrently on the HHS via the global optimizer. The optimized MPS may be usable to construct the physical system. The optimized CP may be executable on the HHS to control the physical system.

Abstract: Described herein are systems, methods, and other techniques for identifying redundant parameters and reducing parameters for testing a device. A set of test values and limits for a set of parameters are received. A set of simulated test values for the set of parameters are determined based on one or more probabilistic representations for the set of parameters. The one or more probabilistic representations are constructed based on the set of test values. A set of cumulative probabilities of passing for the set of parameters are calculated based on the set of simulated test values and the limits. A reduced set of parameters are determined from the set of parameters based on the set of cumulative probabilities of passing. The reduced set of parameters are deployed for testing the device.

Abstract: System and method for machine condition monitoring using phase adjusted vector averaging. An analog signal from a sensor measuring a machine parameter may be acquired, thereby generating a first digital signal that includes multiple analysis blocks of data. For each analysis block, a complex valued frequency spectrum (CVFS) may be computed via a Discrete Fourier transform (DFT), at least one reference frequency may be specified, and a complex valued phase compensation vector that preserves magnitude while adjusting phase constructed to achieve coherence between reference frequency components (RFCs) and the selected analysis block. The CVFS may be phase compensated by multiplying the complex valued phase compensation vector with the complex-valued frequency spectrum. The complex valued frequency spectra of the analysis blocks may be vector averaged, thereby improving signal to noise ratio at specified frequencies. RFCs in the averaged spectrum may be identified, thereby generating average RFCs analyzable to determine machine condition.
