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 additional 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 module behaviour when applying mechanical shocks.
