Application Note
ROHM Solution Simulator

Method for Exporting Circuit Data
The circuit diagrams provided with the ROHM Solution Simulator cannot be edited. In addition, only specified sections of thecomponent properties can be changed. To change these items as desired, it is necessary to use PartQuestTM Explore. Thisapplication note explains how to export the circuit data from the ROHM Solution Simulator to PartQuestTM Explore.

Flow of the circuit data export
Table 1 shows a comparison of the ROHM Solution Simulator and PartQuestTM Explore. They share the operation environment
and the basic simulator. The differences are whether or not the ROHM application circuits are provided and whether or not thecircuit diagrams can be modified.

Explore (Figure 4).

Click

Figure 4. Clicking “Edit in PartQuest Explore” on the lower right of the circuit
diagram automatically exports the circuit data to PartQuestTM Explore.
2. A new Web browser window is opened and the exported circuit diagram is displayed in PartQuestTM Explore (Figure 5).
3. If you do not save the circuit diagram, PartQuestTM Explore can be used as it is.
4. To save the circuit diagram, click the “Login” button on the upper right. If you do not have an account, sign up as a user.

Step 3
1. Now the circuit diagram can be edited as desired. Modify the circuit diagram as desired and perform relevant simulations.
2. To use the saved circuit diagram for simulations in the future, log in to PartQuestTM Explore, instead of the ROHM Solution
Simulator, and open the circuit diagram.
