DRC = determines whether the physical layout of layout satisfies a series of recommended parameters called design rules
ERC = involves checking a design for all electrical connections that are considered dangerous, this might include checking for well and substrate areas for proper contacts and spacings thereby ensuring correct power and ground connections
and unconnected inputs or shorted outputs.
The basic workflow was equal to the 4th week's task - the electronics production - after finishing the design in Eagle I exported the PCB layout as image/png for further processing. And here a technical problem occured - when I exported the png from Eagle everything looked allright -from the visual aspekt. But as soon as I loaded the file into the fabmodules or in an imageeditor the size were scaled up about a factor 2!
