I want to test my circuit but for start i can not get simulation from one simple circuit, when i click  the GND icon i cannot add that to my schematic and only the mouse cruiser  showed like this: ![image](https://i.stack.imgur.com/g4ppk.png) and without that i get this error: ![image](https://i.stack.imgur.com/s8aeW.png) \`This circuit does not have GND\. Please select GND from the circuit tool to add to the circuit\.\` The electronics.stackexchange.com  link: [Why](https://electronics.stackexchange.com/questions/465952/why-can-not-add-gnd-in-easyeda-simulation-mode-this-circuit-does-not-have-gnd) [can not add GND in EasyEDA Simulation mode?

Please do not cross post between different forums. It is not helpful and wastes time having to look at posts that are just copies of what you have already asked. Please read: [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) And study the section on the Tutorial on Basic Skill: [https://docs.easyeda.com/en/Introduction/Basic-Skill/index.html#Left-clicking](https://docs.easyeda.com/en/Introduction/Basic-Skill/index.html#Left-clicking) If this does not solve your issue, please post back with the url to a Public Project which demonstrates the issue you are having. Thanks.

Ii have seen here the answers are referenced to [how to ask help and](https://easyeda.com/forum/topic/How-to-ask-for-help-and-get-an-answer-71b17a40d15442349eaecbfae083e46a) ...some times like: [https://easyeda.com/forum/topic/New-to-easyEDA-user-Please-help-cant-solve-this-error-Fatal-Error-Unknown-subcircuit-called-in-xu1-gnd-xu1-2-cu1-3-vcc-xu1-5-xu1-2-xu1-7-vcc-ne555n-ecb0960f91994056aa7d749c7b4f3c14](https://easyeda.com/forum/topic/New-to-easyEDA-user-Please-help-cant-solve-this-error-Fatal-Error-Unknown-subcircuit-called-in-xu1-gnd-xu1-2-cu1-3-vcc-xu1-5-xu1-2-xu1-7-vcc-ne555n-ecb0960f91994056aa7d749c7b4f3c14) So I do it because saving time and having more view-point and better answer, which have more benefit for users from wasting their time and could be considered as more information. Also i could remove the link after find solution. Also i read the left clicking skill and again i can not add it into my project, so could you give me any video instruction link to see how could i do it? Thanks

OK, you have found this bug: [https://easyeda.com/forum/topic/In-Sim-mode-cannot-select-and-place-Supply-Flags-from-EELib-aba272cbcab44d7598f51d89c64a3c7a](https://easyeda.com/forum/topic/In-Sim-mode-cannot-select-and-place-Supply-Flags-from-EELib-aba272cbcab44d7598f51d89c64a3c7a) In the meanwhile, please use the ground and supply symbols from the **Wiring Tools** palette: ![image.png](//image.easyeda.com/pullimage/Zus9s3sDLYn79V86VcydUwkIyVFWo3czE20W0hMw.png)
