Disk File Names
Disk File Names
Disk files created by the analyzer consist of a state name of up to eight characters, such as
“FILTER,” appended with up to two characters. In LIF format, the file name is
“FILTERXX.” In DOS format, the filename is “FILTER.XX.” The first appended character
is the file type, telling the kind of information in the file. The second appended character is
a data index, used to distinguish files of the same type.
Error-corrected data, raw data, formatted data, memory traces, and calibration files are
FORM 3 data files (IEEE 64-bit floating point format). The other files are not meant to be
decoded. Table 3-4 lists the appended characters and their meanings.
