Hi tjallison, Welcome to EasyEDA. You will find a sinewave Voltage source in the EasyEDA Libs. To find out how to use it, please see: <https://easyeda.com/Doc/Simulation-eBook/Configuring-Voltage-and-Current-Sources.htm#ConfiguringVoltageandCurrentSources>

Thanks Andy. Unfortunately I am still lost. Trying to get my sine to square wave converter to simulate. I am totally new to spice .

Can you share a copy of your circuit and any relevant info or notes so we can maybe help you out? Have you had a look through the rest of our Simulation eBook to get some guidance on how to set up simulations?

Also, have you found this example: ><https://easyeda.com/example/Simulation_Quickstarter-iLN8usOaw> :)
