摘要： A method for programming complex programmable logic devices (CPLDs) to implement a logic function, whereby user-designated locked equations of the logic function are mapped into the macrocells of a function block, and then undesignated (non-locked) equations are mapped into the remaining macrocells. The method shifts product terms between the macrocells to adjust the placement arrangement of the mapped equations, thereby obtaining a placement arrangement which is both valid and meets user-defined timing constraints.

摘要： A method for placing a logic function into the function blocks of a complex programmable logic device (CPLD) to maintain the same input/output pin locations after the logic function is subsequently modified by a user. The method utilizes a weighting function to assign portions of the logic function to the function blocks such that sufficient resources are available in each function block to implement subsequent modifications to the logic function without changing the originally-assigned input and output pin locations. For each portion of the logic function, the weighting function is employed to identify the function block which implements the portion while maximizing the available resources in all of the function blocks. If a particular equation cannot be placed, the method utilizes a corrective measure such as fitting refinement, buffering and logic reformation to place the equation. If the equation still cannot be placed, the weighting function is altered, thereby changing the criteria by which logic portions are assigned to the function blocks. The placement method is then repeated with the altered weighting function.
摘要翻译：一种用于将逻辑功能放置在复杂可编程逻辑器件（CPLD）的功能块中以在逻辑功能随后由用户修改之后保持相同的输入/输出引脚位置的方法。该方法利用加权函数将逻辑功能的部分分配给功能块，使得在每个功能块中有足够的资源可用于实现对逻辑功能的后续修改而不改变原始分配的输入和输出引脚位置。对于逻辑功能的每个部分，采用加权函数来识别实现该部分的功能块，同时使所有功能块中的可用资源最大化。如果不能放置特定的方程，则该方法利用纠正措施，例如拟合细化，缓冲和逻辑重构来排列方程。如果方程式仍然不能放置，则加权函数被改变，从而改变将逻辑部分分配给功能块的标准。然后用改变的加权函数重复放置方法。

摘要： An algorithm is disclosed to partition input variables between a feeder logic block and a receiver logic block. For a given input variable partition, the algorithm assigns both a cost to the number of product terms cascaded from the feeder logic block to the receiver logic block as well as a cost that increases as the number of input variables assigned to the receiver logic block approaches its maximum input width. The costs for a variety of input variable partitions are tested to determine an optimal input variable partition.

摘要： A system and method for routing signals to function blocks of a programmable logic device (PLD) via an interconnect multiplexer (XMUX). All available paths from an interconnect multiplexer input resource to an interconnect multiplexer output resource are first identified. Signals are assigned to XMUX paths in order of number of fanouts to function blocks. The signal required by the most function blocks is assigned first. The costs of the XMUX paths relative to the signal to be assigned are determined, and the signal is assigned to the path having the least cost. The process is repeated until all the signals are assigned. A recovery method uses augmenting paths to assign signals if all the signals could not be assigned using least cost paths assignment.
