Abstract: A method and apparatus according to which a blast resistant shelter is assembled. The blast resistant shelter includes first and second structural members, a third structural member coupled to the first and second structural members, a first airway adjacent the third structural member, and a first blast panel pivotably mounted to the third structural member and adapted to pivot thereabout in response to a blast wave. In a first configuration, the first blast panel is detachably connected to a first portion of the blast resistant shelter and prevented from pivoting about the third structural member so that the first blast panel obstructs air flow through the first airway. In a second configuration, in response to the blast wave, the first blast panel is detached from the first portion of the blast resistant shelter and permitted to pivot about the third structural member to permit air flow through the first airway.

Abstract: A request to send a message from a first component, located on a first processor, to a second component, located on a second processor, is received. It is determined that the second processor can be communicated with via a first bidirectional communication path. It is determined that bandwidth is available on the first bidirectional communication path. It is determined that bandwidth is available on a second bidirectional communication path. In response to a determination that bandwidth is available on the second bidirectional communication path, a data path is created between the first component and the second bidirectional communication path and the request to send the message to the second component is granted. In response to a determination that bandwidth is not available on the first bidirectional communication path or on the second bidirectional communication path, the grant of the request to send the message to the second component is delayed.

Abstract: A request to send a first message from a first component to a second component is received at an arbiter. The first component is located in a first time zone and the second component is located in a second time zone. The arbiter determines that the second component is located in the second time zone. It is determined that the second time zone can be communicated with via one or more communications channels in a first direction. It is determined whether bandwidth is available on the one or more communications channels in the first direction. If bandwidth is available on the one or more communications channels in the first direction, a data path between the first component and the one or more communications channels in the first direction is created and the request is granted. Otherwise, the grant of the request is delayed.

Abstract: A circuit and method for measuring duty cycle uncertainty in an on-chip global clock. A global clock is provided to a delay line at a local clock buffer. Delay line taps (inverter outputs) are inputs to a register that is clocked by the local clock buffer. The register captures clock edges, which are filtered to identify a single location for each edge. Imbalance in space between the edges indicated imbalance in duty cycle. Up/down signals are generated from any imbalance and passed to a phase locked loop to adjust the balance.

Abstract: Electronic component validation testing is facilitated by a method, system and program product which allows the importation of virtual signals derived from simulation verification testing of the electronic component design into electronic test equipment employed during validation testing of the actual electronic component.

Abstract: Securing an integrated circuit, including fabricating the integrated circuit to include a multiplicity of unblown efuses, at least one surrogate efuse that emulates a blown efuse, non-volatile data representing the blown state of the surrogate efuse, and security circuitry; and setting, by the security circuitry when power is first applied to the integrated circuit, a security state of the integrated circuit in dependence upon whether a sensed state of the surrogate efuse is equal to the blown state of the surrogate efuse.

Abstract: A methodology to perform testing of integrated circuits (IC) wherein a reduced number of Input/Output (IO) pins may used to load testing patterns and capture test results from test structures after an IC has been installed in its intended application is provided. This methodology utilizes a software engine that receives and translates a parallel test pattern into serial data patterns operable to be provided on the reduced number of I/O pins. A serial process loader then loads the serial data patterns to the test structures within the IC. The IC receives the serial patterns and in turn translates them into parallel test patterns in order to apply the test patterns to the appropriate test structures. The results are captured and then translated into a serial format for communication from the IC to a test unit for analysis.
