General Settings:
The Session Mode dropdown selects the operating
mode of the system and four options:
1. Live: Local -normal operation mode, all
outputs are applied to the on-board package
holder, and to the surrounding headers (Figure
5)
2. Live: External BNC –in this mode of operation
your device under test should be connected to
the instrument through the BNC terminals.
The board applies stimuli and reads out data
exclusively through the BNC terminals (Figure
6). In the Crossbar Panel the target device
appears as address [W=1, B=1]. WARNING:
Please ensure no package is connected in the
PLCC68 holder or through the header bank.
3. Live: BNC to Local –in this operating regime
the instrument’s biasing circuitry is disabled
and all voltage/current biasing to target
devices is provided through the BNC terminals
(Figure 7). The ArC platform only performs
routing, i.e. directs bias voltages/currents from
the BNCs to the selected device (in PLCC68
package or via header banks).
4. Offline –mode used to visualize previously
acquired measurements through the ArC
system. ArC ONE®biasing hardware disabled.
Working Directory entry allows the user to choose
the directory in which measurement sessions will
be saved. Press the browse button on the right of
the entry to navigate. This can be setup later as well.
Session Name entry sets the name of the session.
Hardware Settings:
Reading Cycles: Every test device resistive state READ measurement is by default an average of n
recorded data points. This entry sets the value of n. A higher number translates into a slower, but more
accurate measurement. n=50 is a reasonable, general purpose choice.
Sneak Path Limiting sets up the sneak path mitigation technique employed in selectorless crossbar
arrays. The user can chose between V/2, V/3.
