FPGA comparison


Tags: FPGA

Comparing FPGAs from different manufacturers and different families is quite tricky as what makes up a “slice” is not the same across all of them, and in newer families LUTs have more inputs.

From what I’ve read, the best metric for comparing capacity is Logic cells/ logic elements, followed by Block RAM.

This was my quick and dirty attempt at comparing the different boards/ FPGAs
