Constrained random simulation using machine learning and Bayesian estimation
Certain aspects of the present disclosure are directed towards a method for circuit testing. The method generally includes: determining a probability distribution indicating prior failure probabilities associated with a circuit design; determining a first likelihood associated with occurrence of at least one failure for the circuit design; determining a quantity of test instances to be performed using simulation to detect the at least one failure based on the probability distribution and the first likelihood; and outputting the quantity of test instances.
Computing devices for predicting electrical tests, electrical test prediction apparatuses having the same, and operating methods thereof
A method of operating an electrical test prediction apparatus includes determining a relationship between first electrical test (ET) data, corresponding to at least one shot region comprising a subset of a plurality of semiconductor chips of a wafer, and electrical die sorting (EDS) data, obtained by measuring a state of each chip on the wafer by a testing device, and predicting second ET data, corresponding to an region of the wafer other than the at least one shot region by performing machine learning on the relationship.
AUTOMATICALLY MAPPING EVENT-BASED SIMULATION DATA TO CYCLE-BASED SIMULATION IN HYBRID HARDWARE DEBUG PLATFORMS
A computer-implemented method is provided. Aspects include receiving first waveform data of a first format, wherein the first waveform data includes event-based simulation data. Aspects include generating second waveform data of a second format based on the first waveform data, wherein the second waveform data is compatible with a cycle-based simulation environment. Aspects include performing one or more debugging operations by processing the second waveform data within the cycle-based simulation environment.
MULTICAST-BASED TESTBENCH FOR DEVICE TESTING
Systems, methods, and other embodiments described herein relate to improving the testing of electronic devices using adaptable interfaces. In one embodiment, a method includes receiving a set of virtual electronic control units, receiving a set of interface devices connected to test devices, simulating wire harnesses where each wire harness contains a subset of virtual electronic control units and a subset of interface devices, both of which are configured to communicate therein based on a multicast protocol, and injecting a fault in a target wire harness affecting a test device connected to the subset of interface devices associated with the target wire harness in accordance with a multicast group assignment.
