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 Table 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.
Figure 4-54
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.
