Re: Difference Logic Cells <=> Slices



A Slice consists of two Look-Up Tables (LUTs) and flip-flops plus some
multiplexers.
Logic Cell is a measure of logic capacity.
Originally, one LC = 1 LUT, but to give credit for the extra logic, a
LUTwas then defined as 1.125 LCs.
My advice:
Forget the marketing numbers, forget LC, and go with:
One Slice = exactly 2 LUTs with their flip-flops and multiplexers and
carry logic.

Hi

I have a question.
What is the difference between Logic Cells and Slices on an FPGA?
I have noticed that on the Virtex-II Pro that the amount of Slices =
amount of Logic Cells * 4/9

Thanks
