DEVICE FOR MONITORING PERFORMANCE AND LOCALIZATION OF DEFECTS IN MODERN DIGITAL ELECTRONIC DEVICES USING A POWER BUS TRANSITION PROCESS IN THE FREQUENCY DOMAIN

摘要

Device for monitoring performance and localization of defects in modern digital electronic devices using a power bus transition process in the frequency domain, which comprises a data portion, which is connected to the switching unit; switching unit, which is coupled to the unit of decryption and allocating of control commands; and the unit of decryption and allocating of control commands, which is connected to the generator of test operations and power supply; the generator of test operations, which is connected to the connector; the power supply is connected to the connector; connector that connects to the U Rkontr, which is included in the gap of ground U and is connected to the connector; block of "images" allocation, which is connected to the connector and amplifier; after the amplifier it is connected analog-to-digital converter (ADC) as well as between the unit of ADC and the switching unit it is included the unit of "images" conversion. Additional resistance Rkontr. is designed to highlight the transient pulse and "images" that occur in the power bus of U, when switching LUs from one state to another (logic zero to logic one or a logic one to logic zero).
