Abstract: One disclosed embodiment may comprise a system that includes a qualification system that qualifies data on an associated bus for capture and provides a qualification signal as a function of at least one signal that describes a characteristic of the data on the associated bus. A data capture system stores qualified data from the associated bus based on the qualification signal and a trigger signal, the trigger signal defining a capture session.

Abstract: A system includes a monitoring system that provides at least one signal as a function of at least some data provided on a bus. A measure of performance for the at least some data is adjusted based on the at least one signal. An analysis system is operative to perform logic analysis of the data on the bus as a function of the at least one signal.

Abstract: One disclosed embodiment may comprise an application specific integrated circuit (ASIC). The ASIC includes memory that stores condition data defining conditions for enabling transitions among a plurality of states and next state data defining a next state associated with each of the respective conditions. A state machine circuit employs the condition data and the next state data to transition from a current state of the state machine circuit to a next state as a function of applying at least one condition relative to input data. The at least one condition is defined by condition data that is associated with the current state. The state machine circuit associates next state data with the at least one condition based on the current state of the state machine circuit. A control circuit provides a trigger signal in response to the current state of the state machine circuit transitioning to at least one predefined state of the plurality of states.

Abstract: One disclosed embodiment may comprise a system that includes a data capture system that stores a set of data from an associated data source in response to a store signal while enabled based on a control signal. A control system provides the control signal based on a number of store cycles relative to an event to define the set of data, the number of store cycles varying based on the store signal.

Abstract: An embodiment of this invention provides a system and method for indicating the orientation of a packaged IC in a socket. An LED is physically mounted to a socket. One lead of the LED is electrically connected to a positive voltage through a socket hole on the socket. When the orientation of the IC package in the socket is correct, the other lead of the LED is connected to a ground path on the packaged IC. As a result, the LED is activated indicating the orientation of the packaged IC is correct.
