Hi, I am currently doing initial analysis on a design. I am researching different FPGA´s regarding the required resources to implement different features. I cannot find a method of relatin...

Hi,

Also if possible is it possible to use convert Logic elements from altera to logic cells in Xilinx. Are there factors that can be used between the respective families?

Basically I am looking for a general approximation of how to interchange between both LUT´s and logic elements and between logic elements and logic cells

If I can prove that LE = 1.0009 LC then Altera will make me very rich and if LE = 0.9999LC then Xilinx will... This is a very hot contentious market issue.

The answer is very hard and design dependant...Your research will be most valuable source of information for us all.
