Definition of the signal line of the List sweep comparator
The definition of the List sweep comparison function signal differs from that of the
level comparison function. It is defined as follows:

Comparison output signal
/ BIN 1 - / BIN 9 and /AUX respectively represents the IN/OUT test results from sweep
point 1 to 10. /OUT represents whether the DUT test approves qualified / unqualified. The
signals are output after the sweep cycle ends.

Control signal
The output of / INDEX (simulation measurement ends) and / EOM (measurement
cycle ends) signal differs as the Sweep mode of List sweep changes.
1. Sequential Sweep mode
/INDEX is output after the last simulation measurement of the sweep cycle is
completed. When the sweep cycle is completed and all test results of the comparator are
avaialbe, /EOM is output.
2.Stepping mode
/INDEX is output after the simulation measurement stepping in each sweep cycle is
