7.1. Examples of Error Detection and Correction

The following examples initiate the ROM content using the .mif file with the associated address shown in the following table.

Single-bit Error

The following figure shows an example of a single-bit error waveform following an SEU event impact on ROM content of address 1Fh. The waveform indicates that there is a two-clock cycle latency on the output with respect to the associated read address. When the ROM content is free from bit-flip, the eccstatus signal shows 2b’00. The ROM content of address 1Fh was initialized with data 51h using the .mif file as shown in the Example of ROM Content Initialization table. The ECC status signal shows 2b’10 indicating a single error bit is detected at the ROM content of address 1Fh. The IP corrects the error at the output.

Three Adjacent Bits Error

The following figure shows an example of three adjacent bits error waveform following a multi-bit upset (MBU) event on the ROM content of address 1Fh. The waveform indicates that there is a two-clock cycle latency on the output with respect to the associated read address. The ROM content of address 1Fh was initialized with data 51h using the .mif file as shown in the Example of ROM Content Initialization table. The ECC status signal shows 2b’11 which indicates 3 adjacent bits error detected at the ROM content of the address 1Fh and uncorrectable data appears at the output.
