1 | Ensure your configuration scheme and board support the required features: remote system update (RSU), single event upset (SEU) mitigation. |
This section describes Agilex™ 5 device configuration features and how they affect your design process.
Configuration Bitstream Compression
Configuration bitstream compression is always enabled in Agilex™ 5 device configuration. The Quartus® Prime software generates configuration files with compressed configuration data. This compressed file reduces the storage requirements in the configuration device or flash memory, and decreases the time required to transmit the configuration bitstream to the Agilex™ 5 device.
For more information about estimated compression bitstream, refer to Agilex™ 5 FPGAs and SoCs Device Data Sheet.
Due to compressed configuration bitstream, passive configuration schemes for example Avalon® streaming interface ×8 and ×16 require the external configuration host to monitor the AVST_READY signal and pause sending configuration data when the AVST_READY low signal is detected.
SEU Mitigation
Dedicated circuitry is built into Agilex™ 5 devices for error detection and correction. When enabled, this feature checks for SEUs continuously and automatically. This allows you to confirm that the configuration data stored in an Agilex™ 5 device is correct and alerts the system to a configuration error.
When using the SEU mitigation features, an SDM pin is used to implement the SEU_ERROR function. This pin flags errors for your system to take appropriate actions. Prior to compiling your design, enable the SEU_ERROR function and select an unused SDM pin to implement the SEU_ERROR function in the Quartus® Prime software.
RSU
The RSU feature allows you to store multiple design images in your serial configuration devices, update your design and reconfigure the device remotely. This feature is available in all Agilex™ 5 devices.
For more information, refer to Device Configuration User Guide: Agilex™ 5 FPGAs and SoCs .
