Abstract :
This work attempts to improve the common understanding of multiple temperature testing by presenting previously unpublished data as well as deriving a simple model for bounding an IC´s performance within the three dimensional space defined by VDD, frequency, and temperature. The model is used to design new temperature screens to improve the resolution between healthy and defective ICs. Temperature based test data is presented for Scan, LBIST, and TDF based MinVDD measurements as well as transistor characteristics needed to parameterize the model. The test vehicles used are 0.25 μm and 0.18 μm CMOS ASICs fabricated by LSI logic.
