    • Systems and methods are provided for mapping logic functions from logic elements (“LEs”) into synchronous embedded memory blocks (“EMBs”) of programmable logic devices (“PLDs”). This technique increases the amount of logic that can fit into the PLD. Where area savings are significant, smaller PLDs may be selected to implement a particular circuit. One aspect of the invention relates to methods for identifying sequential cones of logic that may be mapped into synchronous EMBs. After the sequential logic cones are identified for mapping into a synchronous EMB, the logic cone may be selected, expanded, restructured, and retimed, as necessary, to implement the mapping. Another aspect of the invention relates to techniques for handling architectural restrictions of synchronous EMBs, such as the inability to implement the asynchronous behavior of synchronous logic.
    • 提供了将逻辑元件(“LE”)的逻辑功能映射到可编程逻辑器件(“PLD”)的同步嵌入式存储器块(“EMB”)的系统和方法。 这种技术增加了可以适应PLD的逻辑量。 如果区域节省很大,则可以选择较小的PLD来实现特定的电路。 本发明的一个方面涉及用于识别可以映射到同步EMB中的逻辑顺序锥的方法。 在确定用于映射到同步EMB中的顺序逻辑锥之后,可以根据需要选择,扩展,重构和重新定时,以实现映射。 本发明的另一方面涉及用于处理同步EMB的架构限制的技术,诸如不能实现同步逻辑的异步行为。

    • A cloud point monitoring device which includes thermal conductive surface, cooler, temperature sensor, detection volume, detection wall unit, fiber optic cables for transmitting light, lighter emitter, light detector, and a data acquisition and control unit. The cloud point monitoring device provides an instrument to accurately measure the cloud point of diesel fuel indicate the approximate level of crystallization in diesel fuel that has been chilled beyond its cloud point and indicate the approximate energy content of diesel fuel. The cloud point monitoring device design allows it to be made small enough to be mounted in a fuel system of a vehicle.
