    摘要: A configuration space bus includes a configuration space on a primary interface and an extension or secondary interface in communication with a configuration space of the primary interface. When the primary interface receives a transaction request which it does not recognize, the transaction request is passed to the secondary interface for processing. The primary bus then waits for a response from the secondary bus. If the primary interface receives a transaction request which it does recognize, that transaction request is processed by the primary bus. The extension interface allows the primary bus to receive and process industry standard specification defined commands as well as forward commands defined by a user to the extension bus for processing. Multiple buses may be cascaded to form a primary extension interface, a secondary interface, a third interface, etc. A transaction request is passed down through such a chain of interfaces until an interface recognizes and processes it.

    摘要: A Built-In-Self-Test (BIST) state machine providing BIST testing operations associated with a thermal sensor device(s) located in proximity to the circuit(s) to which BIST testing operations are applied, and a design structure including the BIST state machine embodied in a machine readable medium are provided. The thermal sensor device compares the current temperature value sensed to a predetermined temperature threshold and determines whether the predetermined threshold is exceeded. A BIST control element suspends the BIST testing operation in response to meeting or exceeding said predetermined temperature threshold, and initiates resumption of BIST testing operations when the current temperature value normalizes or is reduced. A BIST testing methodology implements steps for mitigating the exceeded temperature threshold condition in response to determining that the predetermined temperature threshold is met or exceeded. These steps include one of: ignoring the BIST results of the suspect circuit(s), or by causing the BIST state machine to enter a wait state and adjusting operating parameters of the suspect circuits while in the wait state.

    摘要: A system that includes a controller for enabling an enumeration operation. The enumeration operation is performed by a controller (110) and logic elements (120) in a system, such that each logic element in the system assigns itself a unique identifier. Each logic element can then be controlled by another source or have a means to communicate with other logic elements in the system. The unique identifier enables greater system flexibility, thereby reducing cost and improving efficiency.

    摘要: A design structure for a system for and method of performing high speed memory diagnostics via built-in-self-test (BIST) is disclosed. In particular, a test system includes a tester for testing an integrated circuit that includes a BIST circuit and a test control circuit. The BIST circuit further includes a BIST engine and fail logic for testing an imbedded memory array. The test control circuit includes three binary up/down counters, a variable delay, and a comparator circuit. A method of performing high speed memory diagnostics via BIST includes, but is not limited to, presetting the counters of the test control circuit, presetting the variable delay to a value that is equal to the latency of the fail logic, setting the BIST cycle counter to decrement mode, presetting the variable delay to zero, re-executing the test algorithm and performing a second test operation of capturing the fail data, and performing a third test operation of transmitting the fail data to the tester.
