There are very few components that you can simulate in spice in your schematic. Please read the **Preliminary remarks** (3) in (2) in: [https://easyeda.com/forum/topic/How-to-ask-for-help-and-get-an-answer-71b17a40d15442349eaecbfae083e46a](https://easyeda.com/forum/topic/How-to-ask-for-help-and-get-an-answer-71b17a40d15442349eaecbfae083e46a)

--@andyfierman Thanks for the replies but i think there should be an easier way for this, just to simulate i have to go through all those pages(still not done reading by the way) and i am still looking for a way to get to simulation mode still yet, I think a descriptive video will go a long way than those pages. How can i get to the simulation mode, i cant find it for days now. Thanks

Sorry: typo. I should have said: Please read the **Preliminary remarks** **_in_** (3) in (2) in: [https://easyeda.com/forum/topic/How-to-ask-for-help-and-get-an-answer-71b17a40d15442349eaecbfae083e46a](https://easyeda.com/forum/topic/How-to-ask-for-help-and-get-an-answer-71b17a40d15442349eaecbfae083e46a) which are: [https://docs.easyeda.com/en/Simulation/Chapter1-Introduction/index.html](https://docs.easyeda.com/en/Simulation/Chapter1-Introduction/index.html) To get to sim mode: Close all files; then:  * Beware that the simulation tutorial is not up to date with the change to LTspice yet. The copy here is more up to date but not yet online at EasyEDA: [https://docs\.google\.com/document/u/1/d/1OWZVVFRAe\_2NW3WratpkA\_SGuHa5AcRow5ZRfvcoVTU/pub](https://docs.google.com/document/u/1/d/1OWZVVFRAe_2NW3WratpkA_SGuHa5AcRow5ZRfvcoVTU/pub) But as I have already stated, you cannot simulate most of the processors and other digital devices in your schematic in EasyEDA. There are no spice models for the following parts: ESP-WROOM-32; CP2102-GMR; AP5056 (a behavioural model could be built for this but that would be subject to a fee); MPU-6050_C24112 (a behavioural model could possibly be built for this but that would be subject to a fee); Other active device may have models or be generic enough to be modelled by substitution with alternative or behavioural parts. The NCP1117ST15T3G has a model available from OnSemi: [https://www.onsemi.com/pub/Collateral/NCP1117%20PSPICE%20MODELS.ZIP](https://www.onsemi.com/pub/Collateral/NCP1117%20PSPICE%20MODELS.ZIP)

Alright so it safe to assume that the components with no spice models will work out of the box? and also the NCP1117ST15T3G model isn't opening on easyeda or LTspice and when i search Pspice, they say i have to pay, that's a lot of hustle for one component, is there any other way to open the file? Thanks...

The model from OnSemi should run with no modifications in both LTspice native and in EasyEDA. Have you followed the processes described in the EasyEDA Simulation Tutorial about Device Models and Spice Pins numbering? Have you followed the instructions in the LTspice help files to run the model natively in LTspice?

Alright i made progress but one more issue remaining is my NCP117 output is not up to 3.3 volt its coming 2.8 volt , that's probably because of the .model i am using in my simulation  there are so many .models in the NCP1117 Model Library, any help you can offer  me here... Thanks

Try: ``` ncp1117_33-x ``` ?
