Why does the Online SPICE simulation take so much time?
The speed of simulation a trade-off between the complexity of the circuit being simulated and the accuracy of the result and we have chosen simulation setting that provide a good balance between these two factors providing results in a relatively short time. The speed of simulation will also depend on the speed of the internet connection and loading on our servers. If a lot of simulation is to be performed our recommendation is simulate offline by downloading a version of SimPort connect.
