In order to ensure the timing performance during design, some constraints are often added so that the layout and routing can be optimized or go according to our wishes. In the past, we were quite unfa

The ADC core converts the analog signal into 12-bit data and stores it in the conversion storage register. The final result of the input analog voltage satisfies the formula:This paper requires two an
