1.7.4.1.2. Specifying an Error List From Prompt Mode

You can operate the Targeted Fault Injection feature interactively by specifying the number of faults to be 0 (-n 0). The Fault Injection Debugger presents prompt mode commands and their descriptions.
Prompt Mode Command Description
F Inject a fault
E Read the EMR
S Scrub errors
Q Quit

In prompt mode, you can issue the F command alone to inject a single fault in a random location in the device. In the following examples using the F command in prompt mode, three errors are injected.

F #3 0x12 0x34 0x56 0x78 * 0x9A 0xBC +

  • Error 1 – Single bit error at frame 0x12, bit 0x34
  • Error 2 – Uncorrectable error at frame 0x56, bit 0x78 (an * indicates a multi-bit error)
  • Error 3 – Double-adjacent error at frame 0x9A, bit 0xBC (a + indicates a double bit error)

F 0x12 0x34 0x56 0x78 *

One (default) error is injected:

Error 1 – Single bit error at frame 0x12, bit 0x34. Locations after the first frame/bit location are ignored.

F #3 0x12 0x34 0x56 0x78 * 0x9A 0xBC + 0xDE 0x00

Three errors are injected:

  • Error 1 – Single bit error at frame 0x12, bit 0x34
  • Error 2 – Uncorrectable error at frame 0x56, bit 0x78
  • Error 3 – Double-adjacent error at frame 0x9A, bit 0xBC
  • Locations after the first 3 frame/bit pairs are ignored
