My question sounds stupid but how do I fix the error in the image below? It was working and then broke when I reconnected the oscilloscope. The error does not make any sense to me.  Does the software doesn't recognize its built-in components? Thanks ![image.png](//image.easyeda.com/pullimage/kXmpLy2oTvwPbjdMqISYqtG0sX7RA8kLzjXwnWb7.png)

I have it in my computer.  I don't know how to share it.  Also, the MOSFET is a custom component.

You can copy and paste your LTspice netlist here. ![image.png](//image.easyeda.com/pullimage/1EZzrMJMdARx0c2X9PUyn6yCOYMMl0PYmH105tch.png) Reply to this post: insert a Code Block: ![image.png](//image.easyeda.com/pullimage/M17cpVlZfFVh2Y0sZhFIKMkWQiXqL8Oa1nWlix32.png) then paste your copied LTspice netlist into it. <br> <br> <br> <br>

Nevermind.  I can't share my project.  It kept asking me to use EasyEDA for 30 min.  Not sure why there is such requirement but I am going for other simulation software.

The two versions of your netlist both have problems due to the forum posting and parsing process so it is not clear if this line in your second netlist posting: ![image.png](//image.easyeda.com/pullimage/Q5NXvyKouURptZXLWRKgCMYc0BLA3Z0qbcrdSDqZ.png) is what your netlist is really showing or if it is the result of a forum parsing error. If your netlist really is showing that, then that explains the error message but it is not obvious how this netlist error arises. So we still need to see your public project...

@phucly, The30 minutes rule is to try to reduce the huge number of spammers that EasyEDA attracts. You could simply download the EasyEDA Source (.json) file and email it to me @easyeda.com If you do want to use other simulation software, I would recommend LTspice. Or the now freeware Microcap12 and Superspice are quite good too.
