    • Transaction-based hardware abstraction involves a process of using heuristic techniques to identify finite-state machines (FSMs) in a hardware design that process transactions, from which transaction boundaries can be identified. Signals can be abstracted as a result of the transaction-based abstraction. Signals can be classified based on the abstracted design as either transient, temporary, or persistent. Transaction-based abstraction allows a comprehensive test plan to be automatically generated for a device. A test plan comprises a set of conditions called coverage points that are derived based on a signal classification created using transaction-based analysis to identify the architecturally-visible state of the design.
    • 基于事务的硬件抽象涉及使用启发式技术来识别处理事务的硬件设计中的有限状态机(FSM)的过程,从中可以识别事务边界。 由于基于事务的抽象,信号可以被抽象化。 信号可以根据抽象设计进行分类,如瞬时,暂时或持续。 基于事务的抽象允许为设备自动生成全面的测试计划。 测试计划包括一组称为覆盖点的条件,这些条件是基于使用基于事务的分析创建的信号分类导出的,以识别设计的架构可见状态。

    • Transaction-based hardware abstraction involves a process of using heuristic techniques to identify finite-state machines (FSMs) in a hardware design that process transactions, from which transaction boundaries can be identified. Signals can be abstracted as a result of the transaction-based abstraction. Signals can be classified based on the abstracted design as either transient, temporary, or persistent. Transient signals can be identified during the abstraction process as the transaction-processing FSMs that define the transaction boundaries. In the unabstracted design, all combinational signals are temporary since they are set and used in the same time step and all transactions are at least one time step in length. State-holding signals may also be classified as temporary if, after abstraction, they become combinational in the abstracted design. All signals that remain as state-holding signals after abstraction are persistent. Transaction-based abstraction allows a comprehensive test plan to be automatically generated for a device. A test plan comprises a set of conditions called coverage points that are derived based on a signal classification created using transaction-based analysis to identify the architecturally-visible state of the design.
    • 基于事务的硬件抽象涉及使用启发式技术来识别处理事务的硬件设计中的有限状态机(FSM)的过程,从中可以识别事务边界。 信号可以作为基于事务抽象的结果进行抽象。 信号可以根据抽象设计进行分类,如瞬时,暂时或持续。 在抽象过程中可以将瞬态信号识别为定义事务边界的事务处理FSM。 在未设计的设计中,所有组合信号都是临时的,因为它们在相同的时间步长中被设置和使用,并且所有事务都是至少一个时间步长。 状态持有信号也可以被分类为临时的,如果在抽象之后,它们在抽象设计中变得组合。 在抽象之后保持为状态保持信号的所有信号是持续的。 基于事务的抽象允许为设备自动生成全面的测试计划。 测试计划包括一组称为覆盖点的条件,这些条件是基于使用基于事务的分析创建的信号分类导出的,以识别设计的架构可见状态。
