Cyclone V Logic Elements

Hello,

I'm trying to figure out how large a design I can implement in a Cyclone V FPGA. It's widely documented that the device can accommodate 110K LEs. But what's an LE? An inverter? A basic gate? A F/F? A 256 bit shift reg?

TIA for any guidance on this. A spec of some kind on the subject would be really helpful.

Again, thanks,

Bill McDonald

    Hello Bill,
    I assume the article FPGAs: System gates or logic cells/elements? can be helpful: www.eetimes.com/fpgas-system-gates-or-logic-cells-elements
    A fragment from the mentioned article:
    "Each LUT could be used to represent a function that would be the equivalent to some number of equivalent gates. For example, someone once told me that a 4-input LUT could be used to represent functions that were the equivalent of anywhere between 1 and 20+ regular logic gates."

    I would recommend to try to implement your project in the Quartus design system for Intel/Altera Cyclone V family. This device family is supported via free Intel Quartus Prime Lite Edition. (https://fpgasoftware.intel.com/?edition=lite).

    Regards,
    Martin
