8. Conclusions
• LabVIEW Application for .STIL Digital Testing has been presented
• The LabVIEW Application Source Code has been uploaded to
Provence Server and can be easily modified by everyone
• LabVIEW Classes of 5 working days has been done in Provence
Design Center
• PXI system can be easily upgraded with an analog card in order
to synchronize digital generation with analog acquisition
• Next step is to add to the system the IDDQ testing capability
