The parameterisation of the EasyEDA Sources is incorrect. Please use the conventional Voltage and Current Independent Sources as described in: https://easyeda.com/Doc/Simulation-eBook/Configuring-Voltage-and-Current-Sources.htm#Configuring-Voltage-and-Current-Sources We will endeavour to correct the EasyEDA Sources. To help us do that, could you please post a link to a public version of your example. Thanks.

Here is an illustration of why the EasyEDA Squarewave source is wrong: https://easyeda.com/andyfierman/EasyEDA_Source_parameters-3DxOI0iAS The problem is that the expression used to interpret the `Amplitude` and `Vinitial`parameters is wrong. Two alternatives are suggested: One defines a source that sets a peak to peak amplitude of `Amplitude` with the base level of the squarewave set equal to `Vinitial`. The other sets a peak to peak amplitude of `Amplitude` with the mid swing level of the squarewave set equal to `Voffset`. There are two other simulation schematics that illustrate the same problems with the Triangle and Sawtooth EasyEDA Sources. As soon as resource is available we will change the expressions used in the library parts.
