upon clicking the simulate option in esim, the application closes automatically. Unable to perform simulation,how to resolve this issue?
In the tutorials, a particular value is taken for the analysis, and for the source, can we change the values other than putting the same values which is shown in the Tutorial, if we can choose our own values what are the conditions or rules we should follow?
After doing the same procedure as shown in the video , unable to get the same simulation waveforms as shown in tutorial, it is showing a straight line.
Sir, why we haven't used the power flag in the ground wire in the schematic editor whereas we did the same operation for RC circuit's schematic's ground?
couldn't open the astablemultivibrator project on esim. Its throwing the error message as , "Error: The project doesn't contain any .Proj file. Please select the proper project directory else you won't be able to perform any operations." I couldn't even open the file normally which is saved withe the extension ".sch" and if I open normally its redirecting me to the Autodesk Eagle screen, where its asking me to sign in or create an account. How should I go further?
while simulating 555 astable multivibrator the following error shows up. I have checked all the connections in the schematic and found nothing wrong and the error persists. Can u please tell me what the error means in any circuit and how to rectify it.
When i am doing exercise, in device modeling when add button is clicked library files will not appear for diode transistor
I'm unable to get the same simulation output as shown in the tutorial

why pwr_flag is not connected to gnd in astable multivibrator
Whenever editing the parameter value of device, the schematic editor is freezing or dead. We need to click on the outside area of schematic editor.As for beginner, it is hard to connect the devices with wire, we need to be more carefully in connection. It is sometime loosing the connection with rectangle box and give the errors.
is there possibilities of occurring of any error other then global label error?
after complition of circuit unable to open electrical parameter?
why should ignore global label error?
I have drawn the schematic and followed the instruction as per the video tutorial but I am Not getting the exact output graph after simulating it
what to do in Device Modeling
Please help me out regarding issue
