Tz75 Single-Event Upset Detection

The Tz75 FPGA has a hard block for detecting single-event upset (SEU). The SEU detection feature has two modes:

Auto mode—The Tz75 control block periodically runs SEU error checks and flags if it detects an error. You can configure the interval time between SEU checks.
Manual mode—The user design runs the check.

In both modes, the user design is responsible for deciding whether to reconfigure the Tz75 when an error is detected.

Notice: For more information on using the SEU detection feature, refer to the Topaz Interfaces User Guide.

Important: For applications that require the SEU feature, you must implement an external system-level primary functional detection mechanism. You should only use the Topaz™ FPGA SEU detection feature as a secondary indicator and it should not take precedence over the primary detection mechanism.

Note: Contact your local Efinix representative for more system-level design details if your application needs both Over-the-Air and SEU detection.
