A JTAG instruction, EDERROR_INJECT, is provided to test the capability of the error
detection block. This instruction is able to change the content of the 21-bit JTAG fault
injection register that is used for error injection in Stratix IV devices, enabling the
testing of the error detection block.
You can only execute the EDERROR_INJECT JTAG instruction when the device is in user
mode.

You can create a Jam™ file (.jam) to automate the testing and verification process.
This allows you to verify the CRC functionality in-system, on-the-fly, without having
to reconfigure the device. You can then switch to the CRC circuit to check for real
errors induced by an SEU.
You can introduce a single-error or double-errors adjacent to each other to the
configuration memory. This provides an extra way to facilitate design verification and
system fault tolerance characterization. Use the JTAG fault injection register with the
EDERROR_INJECT instruction to flip the readback bits. The Stratix IV device is then
forced into error test mode.
The content of the JTAG fault injection register is not loaded into the fault injection
register during the processing of the last and first frame. It is only loaded at the end of
this period.
You can only introduce error injection in the first data frame, but you can monitor the
error information at any time. For more information about the JTAG fault injection
register and fault injection register, refer to
