A fast methodology and system to characterize setup/hold time for analog IPs are provided. Partial circuits of clock and data paths are simulated instead of the simulation of entire IPs. The partial circuits include all those paths of clock pin and data input pins before reaching first level DFF. This methodology includes multi-path searching of hierarchical SPICE netlist for the path of clock pin and data pins, so as to reduce the circuit subset, merge the paths of clock pin and the data pins, and characterize the setup/hold time for the analog IP. The paths of data pins and clock pin before DFF are used for setup/hold time characterization.

A successive approximation analog-to-digital converter is used for converting an analog input signal into a corresponding digital output signal. The successive approximation analog-to-digital converter has a successive approximation register for storing a first digital bit stream and a second digital bit stream that are related to the analog input signal, and a digital-to-analog converter for generating a first reference voltage and a second reference voltage according to the first and second digital bit streams. The digital-to-analog converter has a first voltage divider and a second voltage divider. The first voltage divider drives the first reference voltage approaching the analog input signal to establish the first digital bit stream, and the second voltage divider drives the second reference voltage approaching the analog input signal to establish the second digital bit stream. Finally, the first and second digital bit streams are averaged to generate the digital output signal.
