Problem with simulation

Im new in Easy EDA, I need do some tests with XL4016E1 and I found one example "running" here. I would like show VoltProbe graph, but I dont have idea how to fix it. Later I will edit this circuit for study the "XH-M400" Buck dc-dc convert. I need see the PWM duty cicle with some inputs and outputs.

Hi andyfierman, before opening this topic, I researched and read a lot of things, including re-reading your statement, but I'm having trouble understanding what the problem would be. I am 4 days tried to simulate the XL4016, but this component is hard to find in other softwares and similar components end up limiting my tests. And it was at EasyEDA that I found a project that seems to be working. For that reason I just tried to simulate something ready, hoping it might avoid my design mistakes, but it still did not work and I do not know how to fix it.

Can you post the link to the project that found which seems to be working.

That is simply a schematic, not a simulation. There is no simulation model for the XL4016 SMPS chip in the EasyEDA system library and the datasheet is not good enough to create an accurate model for it. * Please re-read the introductory paragraphs of the Simulation Tutorial to understand exactly where you can find simulation symbols in EasyEDA. There are a few simulation symbols in the user contributed libraries (i.e. not the System > Spice libraries) but very few of them actually work. I think there is what is shown as a simulation symbol for the XL4016 in a user contributed library but it has no simulation model associated with it so it does not work.

Thanks for everything andyfierman, I read about this possibility of not being able to simulate some components of the design for lack of detail, but since I do not have knowledge of EasyEDA and Spice, I could not interpret the error logs and it was my last hope of virtual simulation. Just to explain my situation is about a study on this Buck converter dc-dc in power electronics on my degree "Engineering of Control and Automation". I would like to do a detailed study with several virtual simulations, including project improvements, improving my knowledge on the subject, but now I will have to restrict some tests with only real non-invasive simulations on the xh-m400 board. Thanks.

@leonardo.krummenauer, If you read the Simulation Tutorial carefully, you will find that, under certain circumstances, EasyEDA can develop models for particular devices. If you would like a model for this device to further your studies, please contact me directly via my username at easyeda. :)
