METHOD FOR MONITORING A CLOCK GENERATOR MODULE OF AN ELECTRONIC CIRCUIT - A simplified explanation of the abstract
This abstract first appeared for US patent application 18408936 titled 'METHOD FOR MONITORING A CLOCK GENERATOR MODULE OF AN ELECTRONIC CIRCUIT
The abstract describes a method for monitoring a clock generator module in an electronic circuit that generates multiple clock signals. A monitoring module outside the circuit selects one of the clock signals as a selection signal, based on which a predetermined PWM signal is generated and output. The monitoring module receives the PWM signal from the circuit, measures it using a monitoring clock signal, compares the measurement result with a predetermined comparison result or range, and determines a malfunction in the clock generator module if the measurement result does not match the comparison result or range.
- The method involves monitoring a clock generator module in an electronic circuit.
- The monitoring module selects a clock signal in the circuit as a selection signal.
- A PWM signal is generated based on the selection signal.
- The PWM signal is measured and compared to determine any malfunction in the clock generator module.
- The monitoring is done externally to the electronic circuit.
Potential Applications: - Quality control in electronic manufacturing processes. - Fault detection in complex electronic systems. - Performance monitoring in critical timing applications.
Problems Solved: - Ensures the reliability of clock signals in electronic circuits. - Detects malfunctions in the clock generator module promptly. - Improves overall system performance and stability.
Benefits: - Enhances the accuracy of clock signal generation. - Facilitates quick identification and resolution of issues. - Increases the efficiency of electronic circuit operations.
Commercial Applications: Title: Clock Generator Module Monitoring System for Electronic Circuits This technology can be utilized in industries such as telecommunications, aerospace, and automotive for ensuring precise timing in critical systems. It can also be integrated into testing equipment for electronic components.
Questions about Clock Generator Module Monitoring System: 1. How does this method improve the overall reliability of electronic circuits? 2. What are the key advantages of using an external monitoring module for clock signal analysis?
Original Abstract Submitted
A method for monitoring a clock generator module of an electronic circuit which is configured to generate a plurality of clock signals for the electronic circuit. A monitoring module external to the circuit alternately causes the selection of one of the clock signals in the circuit as a selection signal; wherein based on the selection signal a PWM signal, whose period duration and holding time are predetermined, is generated and output; wherein the PWM signal is received from the electronic circuit by the monitoring module and measured using a monitoring clock signal to determine at least one measurement result, the at least one measurement result is compared with at least one comparison result or comparison result range, and a malfunction of the clock generator module is determined if the at least one measurement result does not match the at least one comparison result or comparison result range.
