Re: [kicad-users] Power Ports - local or global?

[Hristo Antonov]

Yes they are global i think
look at this
" 1 VSS )
  (2 VDD )
  (3 MCLK_1 )"

this is part of netlist

VSS and VDD are global labels and the MCLK is local label on page 1

Good luck ;)

sorry this was the original message i wrote the first time

   Hi
this cannot be all power symbols are Global
I have tryed a test design evaluating KiCad and it was fine.
Do you have a power port symbol connected to the power nets thou it is 
rarely the problem

The problem is more likely :
You have invisible power pins that EEschema connects automatically like 
VCC on the one page and VDD on the other and the 3V3 power net .
EEschema connects all invisible power pins in groups leaving you to 
believe 


Look at the netlist file
if the net names are 3v3_1 3v3_2  this means that the are not global
see this

" 1 VSS )
  (2 VDD )
  (3 MCLK_1 )"
vss and vdd are global labels and mclk_1 is label mclk in page 1

this could be a major bug so please investigate further
hope you come out of this soon

Are power ports local to a sheet, or are they global across the entire
hiearchy?

For example, my design has mixed analog and digital 3.3 Volt circuits.
My digital circuits are in one sheet, and my analog circuits are in
another sheet, all tied together into a hierarchy.

If I tie "3.3V" to my analog source in my analog sheet, and "3.3V" to
my digital source in my digital sheet, will they become merged as one
node, or will they be two separate nodes (which is the intent)?

Thanks,

Hi,
Have you tried opening the netlist file in CvPCB and then reimporting
the file into PCBNEW?
Please try this and see if it works.

HI 
do you compile the netlist after read?

it is stupid question but it is possible
i had about a 10 corrections in a netlist and everything  went right
I use  "Build Version:
EESchema (2006-06-26) - Unicode version
"

Hi David,

Thanks for the suggestion. It didn't automatically read the netlist,
but it did enable me to override the parts that had changed to update
them (so it did give me a partial solution). I would ideally like to
completely clear the cache if at all possible and re-import from the
beginning. Any idea if this is possible?
