Measuring and Utilizing the Correlation Between Signal Connectivity and Signal Positioning for FPGAs Containing Multi-Bit Buildi

As the logic capacity of FPGA increases, there has been a corresponding increase in the variety of FPGA building blocks. From a mere collection of the conventional logic blocks, FPGAs now can include digital signal processors, multipliers, multi-bit addressable memory cells, and even processor cores; and one of the common characteristics of these new building blocks is their multi-bit design, where each block is designed specifically to process several bits of data at a time. This multibit processing paradigm is significantly different from the single-bit processing design of the conventional FPGA logic blocks; and it creates differentiation in signals through its bussed structures. Consequently, this paper examines the correlation between the positions of the signals in buses and the connectivity of these signals. Based on the correlation measurements, a multi-bit routing architecture is then proposed along with its routing tool. It is experimentally shown that, comparing to the conv...
