I am new to easy pc tool and so please answer my doubts below
1. can v choose negative or positive plane for power planes? 2.how to select individually a routed trace which is underneath the pad? 3.can we set placebound top in this tool like allegro? 4.If we delete the ratsnets mistakenly, it is not visible though I select "show all net connections"?
1) The powerplanes are not normally visible, but can be switched on by VIEW > Powerplane. However, it's best not to use powerplanes in EasyPC because of possibility of isolated islands of copper where there is a high density of vias. Use flood fill areas of copper instead,(ADD >Copper Pour Area) and manually add flood area to +Vcc or Gnd nets manually.
2) Select the pad then press N key (next) until the segment you want is highlighted.
3) ?
4) Try TOOLS > Forward Design Changes from schematic page to reload ratnest.
3."Placebound top" is a shape given around all the components to maintain a minimum clearance (25mil) in the component library. can We give that using the Easy PC tool?
Thanks for your upcoming reply.
