Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual adjustment methods are used to adjust receiving or output timing, then timing can be adjusted, but the process is time-consuming and labor-intensive
Solution Approach 1:
The timing adjustment circuit performs self-adjustment by automatically comparing sampled signals with expected timing and generating adjustment signals to correct timing deviations, eliminating the need for manual intervention and significantly reducing adjustment time while maintaining reliability
Solution Approach 2:
The circuit uses feedback mechanisms where the sampled signals are compared with reference timing, and the comparison results are fed back to adjust the receiving or output timing automatically, creating a closed-loop system that ensures accurate timing without manual intervention
2Measurement precision
If manual adjustment methods are used to adjust receiving or output timing, then timing can be adjusted, but human errors occur and adjustment accuracy is reduced
Solution Approach 1:
The circuit autonomously performs timing adjustment by comparing sampled signals with reference timing and automatically generating correction signals, eliminating human error while maintaining high precision timing adjustment without complex manual operations
3Reliability
If fixed receiving and output timing values are used, then timing is stable initially, but the system is influenced by external factors such as temperature and dust
Solution Approach 1:
The circuit dynamically adjusts timing parameters in response to environmental changes by continuously monitoring signal timing and automatically correcting deviations caused by temperature, dust, or other external factors, ensuring reliable signal transmission under varying conditions
Solution Approach 2:
The system uses continuous feedback from signal sampling and comparison to detect timing deviations caused by environmental factors, and automatically generates adjustment signals to compensate for these changes, maintaining reliable operation despite external influences

AI summary
A timing adjustment circuit and method thereof are disclosed. The timing adjustment circuit at least consists of a second timing adjustment unit, a multistage sample circuit, and a decision circuit for adjusting received timing of an output signal transmitted by a first chip and received by a second chip. The method takes advantage of the multistage sample circuit to receive a clock signal of receiving end so as to generate a plurality of sample clock signal. Later, according to the sample clock signals, sample output signals to generate a plurality of sampled signal. At last, make comparison of the sampled signals by the decision circuit in accordance with the output signals to generate a second adjustment signal being transmitted to the second timing adjustment unit for adjusting phase of a base clock to generate an adjusted receiving-end clock signal. Thus the receiving timing of the second chip to receive the output signal is adjusted. Moreover, the decision circuit sends a first adjustment signal to a first timing adjustment unit of the timing adjustment circuit for generating an adjusted output-end clock signal. Thus the output timing that the first chip transmits the output signal to the second chip is adjusted.
