I have been using DesignSpark a lot. And build 10+ boards from it - most of them small dense 4-layer boards. And I kind of like the tool because of the simplicity yet lack of limitations.
BUT... After having the second case of some traces missing on a board that was manufactured and assembled I had find out why that happens.
Turns out a VERY BASIC FEATURE does NOT WORK!!!
The mechanism that checks schematic netlist against PCB netlist does not work. If you delete part of a trace in the PCB design, the checker will tell you the designs are the same.
This carries into the Forward Design Changes function also, so that DOES NOT WORK either.
This is a total showstopper for me. This needs to be fixed now.
Is there any other way to check for differences between schematic and layout netlists?
This is an essential check before manufacturing of any board.This is why I warn all of you, so you don't risk spending lots of money on boards that does not work - just like I did.
