The paper presents an Advanced Digital Signal Inspector (ADSI) used for acquisition and analysis of the internal digital of a System on Package (SoP) with a limited number of pins. The system is made of a commercial FPGA-board, connected to the module for data sampling and controlled by PC via USB; a suited graphical interface allows for configuration, multi trace real time data display and post processing. The proposed platform can be used to extract and monitor simultaneously up to 4 digital signals, and an ADC is used to monitor one further analog signal. The ADSI has been successfully applied for the characterization of an automotive SoP based on a MEM gyro sensor interfaced to an ASIC for proper signal conditioning. The ADC was connected to an external accelerometer to evaluate the SoP behaviour when applying mechanical shocks.

Abstract
The paper presents an Advanced Digital Signal Inspector (ADSI) used for acquisition and analysis of the internal digital of a System on Package (SoP) with a limited number of pins. The system is made of a commercial FPGA-board, connected to the module for data sampling and controlled by PC via USB; a suited graphical interface allows for configuration, multi trace real time data display and post processing. The proposed platform can be used to extract and monitor simultaneously up to 4 digital signals, and an ADC is used to monitor one further analog signal. The ADSI has been successfully applied for the characterization of an automotive SoP based on a MEM gyro sensor interfaced to an ASIC for proper signal conditioning. The ADC was connected to an external accelerometer to evaluate the SoP behaviour when applying mechanical shocks.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
