摘要： The present invention provides for determining arrival times in a circuit. An arrival time for a main signal is assigned. An arrival time for a secondary signal is assigned. It is determined whether a test is for an early arrival or for a later arrival. If the test type is for a late arrival, it is determined whether the arrival time for the secondary signal is later than for the first signal. If the test type is for an early arrival, it is determined whether the arrival time for the secondary signal is earlier than for the first signal. If the test type is for the late arrival and the arrival time for the secondary signal is later than for the first signal, assuming maximum interference between the signals. If the test type is for the late arrival and the arrival time for the secondary signal is not later than for the first signal, calculating the actual interference between the signals.

摘要： An alternate display content controller provides a technique for controlling a video display separately from and in addition to the content displayed on the operating system display surface. Where the display is a computer monitor, the alternate display content controller interacts with the computer utility operating system and hardware drivers to control allocation of display space and create and control one or more parallel graphical user interfaces adjacent the operating system desktop. An alternate display content controller may be incorporated in either hardware or software. As software, an alternate display content controller may be an application running on the computer operating system, or may include an operating system kernel of varying complexity ranging from dependent on the utility operating system for hardware system services to a parallel system independent of the utility operating system and capable of supporting dedicated applications. The alternate display content controller may also include content and operating software delivered over the internet or any other LAN. The alternate display content controller may also be included in a television decoder/settop box to permit two or more parallel graphical user interfaces to be displayed simultaneously.

摘要： An apparatus, a method and a computer program product are provided for conserving energy during functional mode of a processor by disabling the scan chain. By inserting logic gating into the scan chain it is possible to disable the scan chain during the processor's functional mode. During functional mode the scan out port of the latch bit in a scan chain toggles, which leads to unnecessary energy consumption. By gating scan control signals and the scan out port of a latch bit, the scan chain segment between latch bits can be disconnected. Therefore, the scan control signals can disable the scan chain during functional mode.

摘要： This invention describes a method of synchronizing test clocks in an LSSD system to achieve near simultaneous arrival of the clock signals at the inputs of all LSSD registers. The method relies on pipelining the latches to distribute the test clocks, where all pipeline latches are synchronized by the system clock. This enhancement improves the frequency at which the test clocks switch and improve the testing throughput by reducing testing time, resulting in significant reductions in testing hardware and overall time required for system test, without compromising any of the benefits associated with conventional LSSD techniques. The method further enhances the distribution of the test clock signals to points throughout the entire chip, with a distribution network that is tailored according to a desired LBIST speed.
摘要翻译：本发明描述了一种在LSSD系统中同步测试时钟的方法，以实现时钟信号在所有LSSD寄存器的输入端的近似同时到达。该方法依赖于流水线锁存器来分布测试时钟，其中所有流水线锁存器都通过系统时钟同步。该增强功能可以通过减少测试时间来提高测试时钟切换的频率，并提高测试吞吐量，从而大大降低了测试硬件和系统测试所需的总体时间，而不会影响与常规LSSD技术相关的任何优势。该方法进一步增强了测试时钟信号在整个芯片上的点的分布，其中分配网络根据期望的LBIST速度被定制。
