“…Typically constrained test generation is performed to reflect the capability of the hardware used to generate the test. For example, when testing is performed using software running on the baseband DSP of a transceiver unit, band-limited multitone or transient test stimulus can be used [6][7][8][9][10].…”

Due to the proliferation of nanometer CMOS mixed-signal/RF circuits and a push towards high operating speeds (5-100 Ghz+), there has been renewed interest in the design of high-speed circuits and systems that can self-calibrate and self-heal post-manufacture and in the field. In the past, designers have invented selfhealing mechanisms that are tailored towards specific (critical) mixed-signal/RF performance metrics of specific circuit architectures (transmitter, receiver, etc). What is desired, however, is the ability to monitor multiple performance metrics concurrently and trade them off against one another in an optimal manner, through performance tuning mechanisms, to satisfy system-level Quality of Service (QoS) guarantees. Further, the methods employed must be scalable across different device types/circuit architectures and supported by CAD tools that enable automation of self-healing design procedures.In this paper, recent research advances are presented that allow low cost and rapid selfhealing of complex mixed-signal/RF systems and enable the development of design automation tools to support such activity across diverse performance metrics and circuit types.

“…Adaptation to process variations is also a key issue in other systems such as low-power RF & wireline systems [9][10][11]. In this context, techniques such as self-learning based adaptation [12][13], power-conscious tuning [14] and system level testing and tuning [15][16][17] concepts have been developed. Although a self-tuning approach based on alternative built-in self-test for RF devices has been developed in the past to reduce testing cost and testing time [18][19][20][21], the work reported in this paper develops, for the first time, a testing and self-tuning methodology that avoids the hazards (voltage spikes) associated with standard testing procedures while providing guarantees for the same.…”

This paper proposes a self-tuning architecture for buck converters based on a modified alternative "safe" testing approach. It avoids voltage spikes caused by conventional full load testing and provides measurements with strong statistical correlation with the DUT's specifications. The measurements are sampled by a 5-bit ADC and analyzed by on-chip resources for evaluating the DUT specifications and predicting the corresponding values of buck converter tuning knobs to compensate for process variations when standard perfonnances are not met. Thus, the proposed methodology enables self-test and self-tuning of buck converters during production test without the risk of DUT damage during standard production test. The causes of voltage spikes during conventional full load test are discussed both analytically and numerically and the working mechanism of an alternative test procedure is developed. This proposed technique is demonstrated through both simulation and hardware validation experiments.
