To Add the Measurement Function and Dummy Data
1. Open the Measurement object using the HP VEE program explorer.
2. Create the Vg_spot input terminal in the Measurement object as shown in
Figure 4-25.
3. Open the Meas 4155 object, and add the following three functions. Then set the
parameters shown using the Edit Function Panel of each function.
• hp4156b_opc_Q function
• hp4156b_force function
a. channel : Use gate_ch variable.
b. mode : VOLTAGE OUTPUT
c. range : 0
d. value : Use Vg variable, and create Vg input terminal.
e. comp : 1m
f. polarity : AUTO
• hp4156b_spotMeas function
a. channel : Use drain_ch variable.
b. mode : CURRENT MEASUREMENT
c. range : 0
d. value : Use spot_id variable, and create spot_id output terminal.
e. status : Use spot_id_s variable, and create spot_id_s output terminal.
4. Connect the line between the Vg_spot input terminal and the Vg input terminal
of the Meas 4155 object.
5. Add two Flow-Junction (JCT) objects.
6. Create the spot_id and spot_id_s output terminals in the Measurement object.
7. Connect the lines from the spot_id terminal of the Meas 4155 object to the
spot_id terminal of the Measurement object via the JCT object.
Then connect the lines from the spot_id_s terminal of the Meas 4155 object to
the spot_id_s terminal of the Measurement object via the JCT object.
8. Open the Meas 4155 (Offline) object.
