Hard Lessons Learned (watch out for land mines)

e14 Contributor

So here is my experience with Eaglesoft and Element14 so far and some land mines you may encounter and how to avoid them.  First of all, the libraries that are provided with the software should be immediately discarded.  Don't keep any of them, since you will either end up designing boards that use over priced parts or parts that Element 14 does not have.  Expecially avoid any parts by Farnell, since they don't sell their parts cheap nor do their libraries contain parts that they actually sell.

 

You are better off discarding their libraries and developing your own.  It is not hard to make a part in Eagle cad and if you source your parts and make the designs yourself you won't be disappointed by the irresponsible curation of non existent parts in the default libraries.

  • That has been my experience, sometimes they come out consistent with the design eqs, often it is tweaking with metrology 'til the late hours.  I imagine the old-fashioned alternative, stuff like Pi wound coils, would have been an even bigger design nightmare, I cannot imagine modeling capacitance on a multi-layer, funkily wound coil.  Sometimes, they would make high-Q filters with them!  IIRC, we still don't even have formalisms for something like a Y-shaped core.  Nor, IIRC, do we even have a general formalism for capacitors.  We only have special cases, like parallel plate, or conductive sphere near conductive plane, or two spheres, cylinders.  Amazing that we are able to do so much when we are so ignorant.
