摘要： A clock template includes digital programming information for programming clock frames of a programmable gate array (PGA). The digital programming information represents a number of different clock configurations that correspond to various designs in the PGA. In one embodiment, the digital programming information includes a bit stream for partially reconfiguring the PGA. In another embodiment, the digital programming information is embedded in digital programming information of at least one of the designs. Methods of configuring a PGA with different designs having different clocking configurations by utilizing the clock template are also disclosed.

摘要： A design hierarchy based on an implementation set abstraction of a user design for an integrated circuit design includes a plurality of nodes and a definition for each of the nodes in the plurality of nodes that describes the type of elements contained in each node and the hierarchy defined by each of the nodes. Each node can include at least one implementation element of the design and the at least one implementation element can be selected among the group including a set of logical elements, a set of placed elements, and a set of placed and routed elements.

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： A systematic method for calculating future cost is disclosed. Pre-routing is performed from a source node to other nodes through a series of neighboring nodes. At each node in the pre-routing, the cumulative routing cost and Manhattan distance are calculated. This cumulative routing cost is used as a new future cost for a specific distance if it is lower than or there is no existing future cost for that distance. A table can be used to store the future cost data. During routing, the recorded future cost is added to the cumulative cost of a node to help guide the routing, improving router run-time.

摘要翻译： 披露了一种计算未来成本的系统方法。 通过一系列相邻节点从源节点到其他节点执行预路由。 在预路由中的每个节点处，计算累积路由成本和曼哈顿距离。 如果该累积路由成本低于或没有该距离的未来成本，则将其用作特定距离的新的未来成本。 可以使用表来存储未来的成本数据。 在路由期间，记录的未来成本将被添加到节点的累积成本，以帮助指导路由，从而改善路由器的运行时间。
