Introduction

Welcome to the Max 10 FPGA Configuration Training module. This module will provide an overview of the supported configuration methods for Max 10 FPGAs and describe the value of nonvolatile integration insta non-configuration and dual configuration images.

Configuration Methods for Max 10 FPGAs

Max 10 FPGAs offer various configuration methods to suit different requirements. Let's explore some of these methods:

Nonvolatile Integration Insta Non-Configuration

Max 10 FPGAs feature an internal configuration flash memory (CFM) that can store up to two FPGA images. This integration of configuration memory within the FPGA brings several benefits, including faster startup time, reduced board space requirements, and enhanced security by eliminating exposed configuration interfaces.

Dual Configuration Images

The ability to store two FPGA images in the CFM allows for the implementation of the Dual Configuration feature. This feature finds applications in scenarios where two distinct functionalities are required on the same board or where one device and programming flow need to be shared between two boards with different settings using the select Pin.

Image Compression and Encryption

To optimize the use of CFM, image compression and encryption options are available:

Optional Compression for Single Image Use

For single image applications, image compression is optional. It provides flexibility in managing CFM space.

Required Compression for Dual Image Use

When utilizing the dual configuration feature, image compression is required to fit both images within the limited CFM space.

Design Security through Encryption

To protect intellectual property, images stored in CFM can be encrypted. This ensures secure and tamper-resistant designs.

JTAG Configuration

The JTAG configuration method enables easy programming and debugging during the design phase. It proves particularly useful for real-time testing and troubleshooting.

Applications of Dual Configuration Feature

The dual configuration feature offers two main use cases:

Two Distinct Functionalities on the Same Board

With dual configuration, it is possible to switch between two different signal processing algorithms Instantly. This capability allows for versatile and adaptable designs.

Sharing One Device and Programming Flow between Two Boards

By utilizing the select pin setting, one device and programming flow can be shared between two boards. This provides cost-effective solutions without the need for duplicating resources.

Configuration Process

The configuration process involves the following steps:

Configuring from Configuration Flash Memory (CFM)

Upon power-up, the Max 10 FPGA checks if it is a multi-configuration image system. If not, it configures directly from CFM zero. In multi-configuration systems, the primary input pin and fallback register are considered to select the configuration image.

Multi-Configuration Image System

If a fallback register is set and inverses the boot unor cell input pin, the Max 10 FPGA attempts to configure from the other image if an error occurs during the configuration process. This ensures reliable and fallback-based configuration.

Remote System Upgrade Capabilities

Max 10 FPGAs offer remote system upgrade capabilities. This allows for reconfiguring the FPGA system over various protocols. By including a soft IP controller for the desired protocol, the CFM controller IP handles the update process.

Direct Mode Configuration

Direct mode configuration enables the FPGA to bypass loading the factory default configuration image when a newer application image is Present. This feature minimizes configuration time, even with multiple configuration images.

Bypassing Factory Default Configuration Image

Direct mode configuration skips the loading of the factory default image, reducing configuration time to a minimum.

Achieving Fast Configuration Times

Max 10 FPGAs, whether uncompressed or unencrypted, offer fast configuration times, typically on the order of a few milliseconds.

Configuration Flash Memory Programming

The configuration flash memory (CFM) in Max 10 FPGAs can be programmed in multiple ways:

In-System Programming (ISP)

In-system programming allows the CFM to be programmed via the JTAG interface. This method is suitable for initial programming or reconfiguration.

Realtime ISP

Realtime ISP enables reprogramming the CFM while the FPGA system continues to operate. The changes take effect upon the next reconfiguration.

Remote System Upgrade and User Mode Programming

Max 10 FPGAs provide access to the CFM from inside the user mode FPGA design, enabling remote system upgrades. Additionally, the user flash memory (UFM) can also be programmed via ISP, further enhancing the programmability of the device.

This concludes the Max 10 FPGA Configuration module. Stay tuned for more videos exploring additional Max 10 FPGA features.
