Abstract: A method of jitter measurement is provided and includes sampling a device-under-test (DUT) output signal, having a repeating pattern, using an asynchronous clock over a desired period of time and mapping the samples onto a single period of the repeating pattern. Each period of the repeating pattern is sampled at least twice. A sampling frequency of the asynchronous clock is based on user inputs. Sampling the DUT signal comprises capturing logical state information representing each edge of a single period of the DUT signal at least once. The method further includes, separating the samples into subsets and mapping the sample subsets onto a single period of the repeating pattern wherein the samples within a particular subset are mapped to a set of times which are in the same order as in which the samples were obtained, processing the samples within each subset independently of samples in other subsets, and combining results of the processed subsets and processing the combined results of the subsets.

Abstract: A method and system is provided for detecting and correcting non-deterministic data that provides substantially real-time validation results and maximizes flexibility for the device manufacturer while reducing test costs. The automatic test apparatus and method can correct non-determinism caused by cycle slipping at the beginning of data transmission, between packets of data being transmitted and out-of-order data types of non-determinism. A data validation circuit is coupled to the receiver for validating the packet data based on expected packet data stored in a vector memory.

Abstract: Automatic test equipment for testing non-deterministic packet data from a device-under-test is disclosed. The automatic test equipment includes a memory for storing expected packet data and a receiver for receiving the packet data from the device-under-test. A data validation circuit is coupled to the receiver for validating non-deterministic packet data based on the expected packet data from the vector memory.
