Hi Lanicek, Thanks for your report, however; * Re: `missing initial phase (or delay)` This is not a bug. The sources you are using are the EasyEDA Sources: ![enter image description here][1] and not the much more flexible standard Spice Independent Sources: ![enter image description here][2] The EasyEDA Sources are intended to provide very simple, easy to set up voltage (and current) sources with no parameters other than those given in the right hand Properties panel. These sources already have the AC source option set by default and so do not show it as being a user editable parameters. They do not support any other functions or parameters. Please note that, subject to your bug report: https://easyeda.com/forum/topic/square_with_initial_value-Nz9vQcawE the EasyEDA Sources are under review. If you need more flexibility in your sources then please refer to: The EasyEDA Simulation eBook section on `Configuring Voltage and Current Sources`: https://easyeda.com/Doc/Simulation-eBook/Configuring-Voltage-and-Current-Sources.htm#Configuring-Voltage-and-Current-Sources * Re: `bad result transient analysis` Sorry but it is not clear from your screenshot quite what the issue is because it does not show the name of any probe and does not show the Y axis. It is also not clear if this is a screenshot taken from the schematic that you have included a screenshot of. It is not clear from the screenshot of the schematic if the current source I1 is a 1A DC source realised using the Spice Independent Source or if it is an EasyEDA Source set to 1Hz. It is therefore not possible to reliably comment on what the issue may be. * To avoid confusion, rather than send pictures, please post links to public examples of your simulation schematics. Then we can run them and see exactly what the trouble might be. For information on sharing please see: https://easyeda.com/Doc/Tutorial/share.htm#Sharing Thanks.

http://img5.fotos-hochladen.net/uploads/rectifierq7ay0kt815.jpg in the short time axis is the analysis and chart is good ... but if the simulation with 1s and 0,25Hz current source triangle with amplitude 1A runs in other spice simulation for instance DesignSoft TinaPro (free version Ti-9) the picture will be good. http://img5.fotos-hochladen.net/uploads/tinauazqr8tw0b.jpg thank you

Hi Lanicek, Sorry but your pictures and description are not clear enough. Please put a copy of your simulation schematic into a public project and post the URL: https://easyeda.com/Doc/Tutorial/share.htm#Sharing

Sorry Lanicek, But your images and description are not clear enough. Please place a copy of your simulation schematic into a public folder and post the URL in this thread. https://easyeda.com/Doc/Tutorial/share.htm#Sharing :)

Hi Lanicek, From your reply, am I correct in thinking that you have been able to find a solution to your question? Please post back if you need help with anything else. Thanks.
