Table 8-8: EDERROR_INJECT instruction
DescriptionInstruction CodeJTAG Instruction
Use this instruction to inject errors into the
configuration data. This instruction controls the
JTAG fault injection register, which contains the
error you want to inject into the bitstream.

EDERROR_INJECT
You can only inject errors into the first frame of the configuration data. However, you can monitor the error
information at any time. Altera recommends that you reconfigure the FPGA after the test completes.
Automating the Testing Process
You can automate the testing process by creating a Jam
™
file (.jam). Using this file, you can verify the CRC
functionality in-system and on-the-fly without reconfiguring the device. You can then switch to the CRC
circuitry to check for real errors caused by an SEU.
