摘要： 5. Design Partition Guidelines types of optimizations are prevented by partition boundaries, you can structure or modify your partitions to avoid these limitations.5.1　Register Partition Inputs and Outputs Registers minimize the delays on inter-partition paths and prevent the need for cross-b... 阅读全文

摘要： 4. General Partitioning Guidelines The first step in planning your design partitions is to organize your source code4.1 Plan Design Hierarchy and Design Files hierarchy : the partition includes the assignedinstance and entities instantiated below that are not defined as separate partiti... 阅读全文

Why Plan Partitions and Floorplan Assignmentsmore planning is required setting up the design logic for partitioning may also involve planning placement assignments to create a floorplan more rigorous about following good design practices3.1 Partition Boundaries and Optimization logic opti... 阅读全文

摘要： 话虽如此The same as saying.... however, never the less, yet, on the other hand.Usually it means that they are about to contradict what they just said, or follow up with some exception to what they just said. It implies that they wish to acknowledge that there is more than one side to an issue.For exampl 阅读全文
