Why does the Fault Injection Debugger fail to read the first injected error after device configuration in Intel® Stratix® 10 devices?

Due to a problem in Intel® Quartus® Prime Pro Edition version 20.4 and earlier, the Fault Injection Debugger may fail to read the first injected error after device configuration in Intel® Stratix® 10 devices.

This problem occurs only when the Advanced SEU Detection Intel® FPGA IP is instantiated in the design.

Even when this problem occurs, the SEU_ERROR pin is asserted and the Advanced SEU Detection Intel® FPGA IP still can read the error.

To work around this problem, use the Advanced SEU Detection Intel® FPGA IP to read the first injected error.

This problem is fixed starting with the Intel® Quartus® Prime Pro Edition software vertion 21.1.
