This script calculates the fault-coverage factor for the "inject-on-write"
|
|
fault model, which assumes that writes to memory can get corrupted, and
|
|
completely disregards storage duration (e.g. time between write and subsequent
|
|
read). The metric is calculated from the results of a normal "inject-on-read"
|
|
campaign, only using the FI results from memory accesses that directly follow a
|
|
"write" access.

# Currently does not take into account right-margin writes, i.e. those
|
|
# that are not followed by *any* memory access. This is mostly OK as
|
|
# import-trace creates synthetic 'write' events at the right margin for
|
|
# all but those memory accesses that are exactly on the right margin
|
|
# already.
