Running the test sequence
To run the test sequence, select (click) the 4terminal-n-fet device in the project navigator, and
then click the green Run button . The test sequence is summarized in Tab l e 4- 6 .
Compare the test results
A way to compare id-vg test results is to do a side-by-side visual inspection of the two graphs. In
the project navigator, double-click the two id-vg tests to open them in the Workspace.
To compare the test results:
1.Close some UTMs: To reduce clutter, you may want to remove any other tests (UTMs) from
the Workspace. Figure 4-54 shows the button to close a displayed test.
2.Make room for the two graphs:
a. Hide the project navigator to expand the size of the Workspace.
b. Reduce the size of the test documents.
NOTE The close button (X) is located at the top right corner of the project navigator. Figure 4-54
shows the button to reduce the size of the test documents in the workspace.

Buttons to close or reduce size of test documents
To close or reduce size of test documents:
1.Position tests side-by-side: A test document is moved by clicking the title bar at the top of
the document and dragging it to the desired location in the workspace.
2.Display the graphs: The graph for each test is displayed by clicking the Graph tab.
Figure 4-55 shows typical graphs for the two id-vg tests.
