your schematic contains an unknown component vplot8_1
I downloaded the FreeEDA on UBUNTU-14.04 but the "measurement" library of KICAD was not downloaded. Due to this when I made the project, there was no component available for measurement porpose. Also, I had installed FreeEDA on Windows 8 laptop. There the measurement library was present. So, I tried to manually copy the measurement library file from the FreeEDA of my laptop in the ubuntu PC. After that when I again did the project, the error mentioned above was shown. Please tell me what to do.
Thanking you in anticipation.
Please do not use vplot_8. This facility has been removed from eSim. In eSim you can plot the voltage at any node from interactive plotting.
