Hello again Apakonch,
Sounds like you're having fun!
May I recommend that you read the EasyEDA Simulation eBook:
>https://docs.google.com/document/d/1OWZVVFRAe_2NW3WratpkA_SGuHa5AcRow5ZRfvcoVTU/pub
especially section 4.6 and 5.
There is a copy of the eBook accessible from within EasyEDA but there is a problem with the indexing which is causing a section to be missed out. Until this is resolved, please use the link above.
:)
Thanks for replying quickly again.I am reading this tutorial and it is helping me.
Why I'm not able to simulate dc pt simulation in this circuit ( https://easyeda.com/editor#id=aHF1ZlH2o ). I am able to simulate if I remove LED from this circuit. I've imported LED from eagle library.
That one is simple.
You have no spice model associated with that LED symbol.
If you replace it with one in the EasyEDA Libs then the sim will run.
You can inspect the netlist to see what the LED model looks like and if you need a particular LED model then you can paste it into the schematic, set it to `Text type > spice` and edit the LED name to that of your pasted in model.
This is the default EasyEDA LED model:
.MODEL LED D
+ IS=661.43E-24
+ N=1.6455
+ RS=4.8592
Beware though, there are not many commercial LED models available so you may just want to play with the `N` (approximately the number of standard diode drops of roughly 0.55 to 0.7V) and `RS`(forward resistance) parameters of a standrad diode model to get about the right forward drop for a given forward current.
The default model has a drop of approximately 1.6455*0.6V and a forward resistance of 4.85892 Ohms.

Hi, I got your point. As LED is available in EasyEda library, it can be used. But how to simulate a component which is not a part of easyeda.Please tell the whole process step by step so that I may understand it easily.
1) First you need to either:
a) find a suitable symbol from the EasyEDA Libs and edit it to the exact name and the type of spice model you want to use.
or
b) create a symbol using **Create a new Spice Symbol** that calls up the exact name and the type of spice model you want to use.
* Please document the symbol carefully including links to any datasheets and the source of the spice model when you save this symbol into **My Parts**.
2) Then you need to either paste a spice model (.model or .subckt) into your schematic and set `Text type = spice`.
