Mixed signal SOCs with integrated RF and power management modules have some distinct requirements associated with them. They are often used in portable and battery operated consumer applications, which are extremely cost and power sensitive. This translates into a few unique design and test constraints on the amount of DFT logic integrated, the permissible test time, and power-up of individual modules...
This paper discusses some specific circuit, and analog DFT techniques and methodologies used in integrated power management (PM) systems to overcome challenges of mixed-signal SoC qualification. They are mainly targeted at achieving the following: 1. Enabling the robust digital and system level test and burn-in (BI) with external supplies by disabling the on-chip PM with robust power-on performance,...
The implementation of complex functionality in low-power nano-CMOS technologies leads to enhance susceptibility to parametric disturbances (environmental, and operation-dependent). The purpose of this paper is to present recent improvements on a methodology to exploit power-supply voltage and temperature variations in order to produce fault-tolerant structural solutions. First, the proposed methodology...
