Info

What Can’t Be Expected with Mixed-Signal Simulation • Due to the capability of digital simulator, only time domain information can be obtained directly. • All the modeling of analog behavior should be converted into time domain when simulated with mixed signal simulation. • Other system characteristics such as frequency response might be calculated from time domain data if needed. • When obtaining frequency domain information, the time domain information must provide sufficient time period and time point. 20 Mixed-Signal IC Design Kit
What is Required for Mixed-Signal Simulator Is the model appropriated ? Device model supported Analog/digital interface Is the result reliable ? Algorithm, methodology Is the algorithm stable ? Ease of convergence Complete ? Design formats, language supported Is the simulator efficient ? Ease of using Fast of simulation Clear of output result Ease of extracting desired parameter 21 Mixed-Signal IC Design Kit
