Abstract

Programmable logic device design software is provided for allocating specific resources in a programmable logic device having a multiplicity of programmable logic blocks interconnected by a programmable switch matrix to logic equations in a user logic design. In particular, a resource allocation means for fitting a logic design to a multiplicity of programmable logic blocks with limited interconnectivity between the modules is provided. The resource allocation means requires minimal programmable logic device resources to achieve the allocation of resources within the programmable logic device to the user logic design. The resource allocation means employs block partitioning means and resource assignment means to map user logic to a programmable logic device (PLD) having multiple programmable AND fixed OR arrays interconnected by a programmable switch matrix, i.e., allocate the PLD resources to the user logic.
