Recently LTE RF device has more than 3000 test items. It takes long time to complete the test program. after reviewing the test plan from IC designer. When the development period is pulled in than expected, the test engineer is under pressure to complete the code fast and accurately.

Customized RF standard library helps the time saving for the test program development,
test time reduction and easy to code and debugging.

The idea is that customized standard library is matched to the format of the test plan from IC designer. It makes the information of test plan move to the test program easily and fast. And all of VBT code and the format of the test condition is reusable for next product because only small change such as specification and number of ports will be made.

IGXL is based on Excel and IGXL version in UltraFlex can provide maximum 60 variables in Test Instance It makes that the necessary test information from the test plan is included to the test program. In customized standard library, the format of the test information is matched to the test plan through the cooperation of IC designer and the test items are categorized in ports(RX/TX) and block(2G/4G/5G). And in order to optimize the test program, customized standard library includes the embedded auto script to generate RF and baseband signal of UltraWave8G and UltrPac300 when validating IGXL.

Her is the customer’s feedback regarding the customized standard library.

1. Time saving for Test Program Development: > 50%
2. Test Time Reduction: 8.8%
