Eaglecad 6.4.0: the new LTspice IV import/export capabilities

Eaglecad 6.4.0 has been released and now we have available a very useful feature: we can import and export schematics and libraries between Eaglecad and LT SPICE IV with a single mouse click. As usual Eaglecad is available for windows, linux and mac; you can download the latest version for your operating system here: http://www.cadsoftusa.com/download-eagle/?language=en

The first thing you’ll see after update to the latest Eaglecad version is the LTC SPICE icon, visible on the right in the “Command texts” bar:

LT_ICONLet’s see a simple example which shows a simple solid state digitally controlled delayed switch:

There are many CAD developed to assist the electronic designers during drawing of PCBs and schematics; often they are integrated in complete suite to project, simulate and realize a whole electronic system.
