There may be better tools for this such as the high end tools from Keysight, Mentor and Cadence but of course they are expensive. Running the simulation from there is easy. There are also a couple of ADC and DAC device models.Ĭoming back to your question however, simulations of PCBs traces and device interfaces can be done in EasyEDA but you have to appreciate that it is a labour intensive task because you have to find the PCB dielectric and copper parameters to calculate the trace impedance and lengths and then manually implement those parameters in individual transmission line segments to map the PCB back into a representative schematic. That said there are spice symbol libraries in EasyEDA with detailed behavioural models of 74HC and 4000 series devices many of which are in fact modelled as state machines. Such devices require far too much processor time to simulate using spice simulation tools even when using the built-in digital modelling features of simulators like LTspice or Ngspice. Simulation of digital circuits is very much possible using EasyEDA but it is not the best tool for trying to model clocked devices with complex internal states programmable devices such as microcontroller. I think you misread the Preliminary Remarks in the Simulation Tutorial. "It is stated in the simulation intro that it is not possible to simulate digital circuits in EasyEDA."
