[kicad-users] ERC errors on schematic and power supply questions

[Stephrac74]

Hi group,

 

I’m new user of Kicad. I’ve to say that I’ve used plenty of CAD software and
this one looks really good… I’m playing with it since 2 months and there are
two points I can’t find the solution.

Two words about myself : I’m a french electronic engineer, I’m now leading
project in the industry but I’m also hamradio and I’m designing a lot for
this hobby.

Currently I’m designing a digital milliwattmeter.

 

I believe I will be often on this group for the following weeks….

 

Now, here are my questions

 

1.       When I perform the ERC test on my schematic there are always some
pins marked as error whereas it seems correct. If I redo the wiring then the
error might disapear but appear somewhere else !

2.       Some parts in lib have their VCC/GND pins invisible but they are
not automatically connected to my power supply even if I’ve labelled my +5V
as VCC and as VDD…  What is the trick ? This is the same for parts I’ve
designed with power supply input set as ‘power supply input’

 

 

Many thanks for your support

Stephane
