Integer Unit Test (iutest) |
The Integer Unit Test (iutest) tests the resident integer unit in Sun SPARC CPUs. It exercises all of the register windows present in the integer unit of the CPU. The successful completion of the test implies that all of the register windows are functioning properly and failure implies a faulty register.
To reach the following dialog box, right-click on the test name in the System Map and select Test Parameter Options. If you do not see this test in the System Map, you might need to expand the collapsed groups, or your system might not include the device appropriate to this test. Refer to the SunVTS User's Guide for more details.
Test Depth is the only required test option. Test Depth corresponds to the number of times that all the register windows are getting tested. The default, maximum, and minimum values of the Test Depth are 8, 64, and 1 respectively.

TABLE 29-2 describes the iutest command-line syntax.
The test behavior is unpredictable if options other than those described in this section are entered.
