Slices on an FPGA Chip

Updated Aug 19, 2022

Overview

This article explains how many slices are contained in the FPGA chip on an NI FPGA product.

Introduction

NI FPGA products use chips manufactured by Xilinx. Hardware resources on an FPGA are indicated by the number of slices that FPGA has, where a slice is comprised of look-up tables (LUTs) and flip flops. The number of LUTs and flip flops that Xilinx defines to make up a single slice is different based on the family of the chip.

The table below details Xilinx FPGA families used by NI and how a each family defines a slice.

With an understanding of how an FPGA slice is defined, you can now look at how many slices each FPGA contains. The table below lists the model number of NI devices, the FPGA contained in each device, and the number of slices on that FPGA.

For additional information on FPGA resources such as logic cells, block RAM, and DSP48 slices, please view the Xilinx Family Overview links in the Additional Resources section below.
