摘要： The present invention provides a new method to handle power and ground signals in modular design of programmable logic devices. During module implementation, the power and ground signals of each module are associated with area constraint properties. When performing routing in the module implementation phase, the power and ground signals together with regular local signals of the module are routed in accordance with their respective area constraint properties. However, the area constraint properties of the power and ground signals are removed during assembly phase while the area constraint properties of the local signals are retained.

摘要： A method of placing circuit elements of a partitioned circuit design on a target programmable logic device (PLD) can include mapping circuit elements of the circuit design to corresponding partitions of the circuit design, selecting a circuit element of the circuit design, and selecting a candidate location within a logic boundary on the target PLD. The method also can include validating the candidate location for the selected circuit element, at least in part, according to whether the selected circuit element belongs to a same partition of the circuit design as at least one other circuit element already placed within the logic boundary. The selected circuit element can be selectively placed at the candidate location according to the validation.

摘要： A method of managing behavior of algorithms includes specifying governing rules/policies that manage I-Set implementation directives, command line options, and environment variables and loading governing rules/policies into a behavior manager. Inside a client tool, the I-Set hierarchy processes and iterates one I-Set node at a time. Without more I-Sets to process, the method is done. If more, then the tool queries the Behavior Manager with an I-Set with symbolic designators of the queried behavior. The Behavior Manager can reply to the client tool indicating whether the queried behavior is to be supported on the appropriate logic of the I-Set node. If the algorithm for the I-Set node lacks the queried behavior, then another I-Set might require processing. If the algorithm for the I-Set node has the queried behavior, then the client tool applies the corresponding algorithm(s) on the appropriate logic.
摘要翻译：一种管理算法行为的方法包括指定管理I-Set实现指令，命令行选项和环境变量的管理规则/策略，并将管理规则/策略加载到行为管理器中。在客户端工具中，I-Set层次结构一次处理并迭代一个I-Set节点。没有更多的I-Sets要处理，该方法就完成了。如果更多，那么该工具将使用具有查询行为的符号指示符的I-Set查询“行为管理器”。行为管理器可以回复客户端工具，指示是否在I-Set节点的相应逻辑上支持查询行为。如果I-Set节点的算法缺少查询行为，则另一个I-Set可能需要处理。如果I-Set节点的算法具有查询行为，则客户端工具将相应的算法应用于适当的逻辑。
