Honored ContributorHello Members,
My question: What is the cost of implementation, in terms of logic elements, frequency, memories, area ..., of the logic and arithmetic operations (addition, subtraction, multiplication, division ...) in fpga cyclone ii? for example, to implement a multiplier 2*2 bits, how much we need: + Logic elements + memory + Frequency + area +... Regards,
Honored ContributorYou can find that out easily by creating and compiling a simple verilog or vhdl with the circuit you are interested in. Quartus produces comprehensive reports of resource usage on a particular FPGA family when you compile.
Honored ContributorHonored ContributorI should have mentioned specifically in my reply that I don't know of any such documentation. I don't know if a given operation will always take the same resources. It might depend on the context and on what timing constraints you've entered. I know I've seen resource usage change significantly by what look like small changes to code and/or timing constraints.
Honored ContributorThere is no such data available, because the synthesisor can do lots of work to minimise logic usage depending on your design. Also, the device family has a large effect on resource usage depending on whether it uses 4/6 input LUTs.
So there is no such thing as logic usage for a basic block.Honored ContributorHi,
Yah I agree to Galfonz. The best way to figure this out is to write a sample code and synthesize it. Because the number of logic elements will differ for different devices and timing constraints. Thanks,
