    摘要: Embodiments of the invention provide a logic simulation having a controllable delay model implemented therein that may be used to validate AC I/O loopback design in a pre-silicon environment by introducing delay models that allow the logic simulators to simulate analog behavior. For one embodiment of the invention, a fixed processor ratio is selected and delay statements of the hardware description language correspond to a specific time delay. These fixed values provide the ability to accurately determine and adjust delay in an analog simulation.

    摘要: A multi-bit test value is loaded into a built-in latch of the IC component, and a pad of the component is selected for testing. A number of different sequences of test values are automatically generated, based on the stored test value, without scanning-in additional multi-bit values into the latch. A signal that is based on the different sequences of test values is driven into the selected pad and looped back. A difference between the test values and the looped back version of the test values is determined, while automatically adjusting driver and/or receiver characteristics to determine a margin of operation of on-chip I/O buffering for the selected pad.

    摘要: A system to vent a moist gas stream is disclosed. The system includes an enclosure and an electrochemical cell disposed within the enclosure, the electrochemical cell productive of the moist gas stream. A first vent is in fluid communication with the electrochemical cell for venting the moist gas stream to an exterior of the enclosure, and a second vent is in fluid communication with an interior of the enclosure and in thermal communication with the first vent for discharging heated air to the exterior of the enclosure. At least a portion of the discharging heated air is for preventing freezing of the moist gas stream within the first vent.
