  OK, that explains the need for a lot of layers.  But how does the need
  for blind/buried vias arise?
 
 The balls of the BGA occupy most of the real estate available on top 
 layer. If all vias penetrate the hole stack, this occupation maps to all 
 other layers too.

Actually most often the top layer looks like a two interlaced grids:
- one grid of pads to solder the balls,
- one grid of vias that go allow to route the signals to other layers

That's as long as you don't use exotic techniques like via-in-pad.

Basically the two outermost rings of the BGA can be routed on the top
layer (there is room for one trace between pads). The next two rings
can be routed to the second copper layer with simple vias. But then
every additional ring needs one layer if you don't have blind vias
(buried vias are not necessary for BGA exit patterns), since there is
only room for one trace between vias. With blind vias it is possible
to route 2 rings per layer, and this adds up quite fast for large BGA.

Of course there are also sometimes stupid packaging decisions by
manufacturers, one example is the Spartan3A in BGA256 package where
they decided to put some power connections on the second ring. The worst
case: on the first ring it is easy to put a via just outside without
blocking the exit for the second ring, from the third ring on you
need a via anyway. Spartan2/2E in the same package did not have
this stupid pinout.

Therefore realistically blind vias for BGA exit patterns are only
necessary for 20x20 matrices and larger (the center is often taken
by power supplies which are easier to route).

Re: gEDA-user: Blind and buried vias?

2009-09-30 Thread spuzzdawg

I'm not sure why it's apparently irrelevant that the accepted predominant
workflow is from gschem to pcb

So what? What are all those other back ends for? Aren't they important?

 or that pcb is a member project of the
geda project. If member projects and affiliated projects aren't
considered part of gEDA then I'm curious as to what you define  
 as gEDA
and what topics you define as appropriate for this list.

The issue isn't what topics are appropriate. The issue is keeping the  
interfaces clean and flexible. To do that, you have to remember what  
the interfaces are.

   What other backends? Are you referring to netlister and others? Most
   of them exist to modify schematic files to get it ready for a pcb.
   Otherwise I guess you could mean spice or other simulators. Either
   way, other backends are not particularly relevant to the discussion.
   The discussion was about
   why others consider pcb to be a part of gEDA.
   To keep the interfaces clean and flexible you have to remember what
   the interfaces are? I have no idea what you are trying to say.
   The OP said:


 What's the current and planned state of support for blind and/or  
 buried
 vias in the gEDA system?
That's like asking what's the state of support for driving Phillips  
head screws with a handsaw?.

Another patronising analogy. I think last time you used a chainsaw. 
Pretty much everyone else on this list includes pcb in the geda name, those who
 don't know that others do. It's obvious from
context what the question meant regardless of what your stance is on gEDA termi
nology. I think that all things considered, your
response was deliberately antagonistic.

   

Currently, the gEDA project offers a mature suite of free softwareapplica
tions for electronics design, including schematic capture,
attribute management, bill of materials (BOM) generation,  
 netlisting
into over 20 netlist formats, analog and digital simulation, and
printed circuit board (PCB) layout.

I don't know who wrote that. gEDA and PCB are separate, independently  
developed projects. They have different source trees and conventions.  
They were not originally designed for each other. That they play well  
together is a testimony to the power of clean interface design. Let's  
not forget that, because if we do we will lose that power.

   It comes from the gEDA front page [1]http://www.gpleda.org/
   That they play well is a testament to the fact that the netlister was
   written specifically for use with pcb and that the pcb project is
   affiliated with the gEDA project.
   [2]http://en.wikipedia.org/wiki/GEDA#History
   From the same wiki article:
   Loosely speaking, the term gEDA Suite refers to all [3]free software
   projects and applications that have voluntarily associated themselves
   with the gEDA Project via the geda-dev/geda-user mailing lists. These
   include:
 * gEDA/gaf - gschem and friends (the original project)
 * PCB - PCB layout program   -- take note of this one
 * Gerbv - [4]Gerber file viewer
 * ngspice - a port of Berkeley [5]SPICE
 * GnuCap - A modern [6]electronic circuit simulation program
 * gspiceui - A [7]GUI front end for ngspice/GnuCap
 * gwave - An analog [8]waveform viewer
 * Icarus Verilog - A [9]Verilog simulator
 * GTKWave - A digital [10]waveform viewer
 * wcalc - [11]Transmission line and electromagnetic structure
   analysis

   Within the gEDA Suite, gEDA/gaf (gaf stands for gschem and
   friends) is the smaller subset of tools grouped together under the
   gEDA name and maintained directly by the gEDA project's founders.
   GEDA/gaf includes:
 * gschem - A [12]schematic capture program
 * gnetlist - A [13]netlist generation program
 * gsymcheck - A syntax checker for schematic symbols
 * gattrib - A [14]spreadsheet program for editing symbol attributes
   on a schematic.
 * libgeda - Libraries for gschem, gnetlist, and gsymcheck
 * gsch2pcb - Forward annotation from schematic to layout using pcb
 * Assorted utility programs

Anyone who brings up a point about how

geda/gaf/pcb could be more useful, more user friendly etc

More useful and friendly to *what kind* of user? The kind that would
prefer spending an hour mousing around to solve a problem once, or 15
minutes writing a script to solve it for all time?

   This is the line of argument I really have an issue with. I mean

As noted in the NEWS file (under 1.5.2 changes):

* Major, *backwards-incompatible* changes to color handling in
  `libgeda' and `gschem'.

  - All colors are specified using hexadecimal `#RRGGBB' or
`#RRGGBBAA' syntax.

  - The print and display color maps are now separate.

  - A new Scheme syntax is used to inspect and modify color maps.

  - If you wish to use a light background in `gschem', add the line:

  (load (build-path geda-rc-path gschem-colormap-lightbg))

to your personal or project gschemrc file.

Changing the display colour map *intentionally* doesn't change the print 
colour map (so you can optimise the colours for each). Unfortunately, PNG 
output still uses the display colour map (this is due to the way PNG output is 
implemented).

To change the colours printed, you should edit (or copy and edit) the 'print-
colormap-lightbg' file, and then edit your gafrc file to load it.  Look in the 
'system-gafrc' to see how to do that.

It should still be possible to swap between colour and BW printing using the 
same mechanisms as before 1.5.2.  If this is broken, please file a bug report, 
including the gschemrc  gafrc files you used.

Thanks,

  Peter

 I couldn't get a white background even when I changed the on-screen

 are getting expensive to print

Try adding the following to your gafrc:

  (load (build-path geda-rc-path print-colormap-lightbg))

As I mentioned in another e-mail, the print colours are *intentionall* 
decoupled from the display colours: what's comfortable to look at on-screen

Yes and there are *many* ways to get from a set of gEDA schematics to

great strength of gEDA, one of the things that make it superior to  
other toolkits.

 Otherwise I guess you could mean spice or other simulators.

There are four working ASIC chip designs I created with gEDA. How do  
you suppose that happened?

 Either way, other backends are not particularly relevant to the

No, they are *essential*, because they represent one of the things  
that makes gEDA special. And they give the lie to the notion that pcb  
limitations are gEDA limitations.

 The discussion was about
 why others consider pcb to be a part of gEDA.

 To keep the interfaces clean and flexible you have to remember what

Don't treat gEDA/pcb as just another integrated tool. The world is  
infested with those. Remember that gEDA is better because, with its  
clean interfaces, it can work with other toolkits. To a lesser extent  
that true of pcb, too (as we have heard from an xcircuit user).


 The OP said:

  What's the current and planned state of support for blind and/or  
  buried  vias in the gEDA system? That's like asking what's the  
 state of support for driving Phillips head screws with a handsaw?.

 Another patronising analogy. I think last time you used a chainsaw.  
 Pretty much everyone else on this list includes pcb in the geda  
 name, those who don't know that
 ^^^

That's almost certainly because pcb doesn't have its own list. I have  
the impression that users have a lot more questions about pcb than  
gEDA, so the list is dominated by pcb-centric concerns.

 others do. It's obvious from context what the question meant  
 regardless of what your stance is on gEDA terminology. I think that  
 all things considered, your response was deliberately antagonistic.

*You* call *me* antagonistic? Come on, now.

The question implied a limitation in gEDA. There is no such  
limitation. Is is good to allow such misinformation to tar gEDA's  
reputation?

 

 Currently, the gEDA project offers a mature suite of free  
 softwareapplications for electronics design, including schematic  
 capture,  attribute management, bill of materials (BOM)  
 generation,  netlisting  into over 20 netlist formats, analog  
 and digital simulation, and  printed circuit board (PCB) layout.  
 I don't know who wrote that. gEDA and PCB are separate,  
 independently  developed projects. They have different source  
 trees and conventions. They were not originally designed for each  
 other. That they play well   together is a testimony to the power  
 of clean interface design. Let's not forget that, because if we do  
 we will lose that power.
 It comes from the gEDA front page http://www.gpleda.org/

 That they play well is a testament to the fact that the netlister  
 was written specifically for use with pcb

Nope. gsch2pcb was written for pcb, but gnetlist is a nice, clean,  
pretty neutral general-purpose tool. I see no pcb-specific code at  
all in gnetlist outside of the pcb back end. If anything, gnetlist is  
specialized for Verilog: there is some undocumented Verilog-specific  
code in the front end, and if we ever actually get around to  
refactoring gnetlist, that should be moved to the back end, and the  
back end data access limitations that pushed that stuff into the  
front repaired.

 and that the pcb project is affiliated with the gEDA project.  
 http://en.wikipedia.org/wiki/GEDA#History

If you look in the dictionary, affiliated does not mean the same  
or a part of.


 From the same wiki article:
 Loosely speaking, the term gEDA Suite refers to all free software  
 projects and applications that have voluntarily associated  
 themselves with the gEDA Project via the geda-dev/geda-user mailing  
 lists. These include:

 gEDA/gaf - gschem and friends (the original project)
 PCB - PCB layout program   -- take note of this one
 Gerbv - Gerber file viewer
 ngspice - a port of Berkeley SPICE
 GnuCap - A modern electronic circuit simulation program
 gspiceui - A GUI front

Re: gEDA-user: [spicelib] how to run the tests ?

2009-09-30 Thread asomers
Probably you need to do this:

edit scripts/geda-parts.scm and fix the path to your repository.

If it still doesn't work, send me the output, both to the terminal and
the html, of
scripts/testlibrary -p indexfiles/nxp_diodes.index BAS116H_NXP01004

 Hi Werner and Alan,

 I just re-forked/re-cloned spicelib on github.com from Werners
 repository.

 Getting and installing the models with make all just seems to work.

 Running make test does run the test script, but all tests seem to
 fail.

 I think I need to do something in between make all and make test but
 can't find any clues in the README or doc/index.html.

 Can you give me any clues what to do ?

 Kind regards,

 Bert Timmerman.

Re: gEDA-user: Color PS output

 Hi,
 I just tried to generate color Postscript output in both
 1.5.2.20090328 and 1.5.4.20090830 and found that it won't work. Is
 anyone else having this problem? My gschemrc file has

 (output-color enabled)      ; for color postscript output
 (image-color enabled)       ; for color PNG output (enabled by default)

 copied from the wiki. Could someone please tell me what am I doing wrong
  here?


 As noted in the NEWS file (under 1.5.2 changes):

 * Major, *backwards-incompatible* changes to color handling in
  `libgeda' and `gschem'.

  - All colors are specified using hexadecimal `#RRGGBB' or
    `#RRGGBBAA' syntax.

  - The print and display color maps are now separate.

  - A new Scheme syntax is used to inspect and modify color maps.

  - If you wish to use a light background in `gschem', add the line:

      (load (build-path geda-rc-path gschem-colormap-lightbg))

    to your personal or project gschemrc file.

 Changing the display colour map *intentionally* doesn't change the print
 colour map (so you can optimise the colours for each). Unfortunately, PNG
 output still uses the display colour map (this is due to the way PNG output is
 implemented).

 To change the colours printed, you should edit (or copy and edit) the 'print-
 colormap-lightbg' file, and then edit your gafrc file to load it.  Look in the
 'system-gafrc' to see how to do that.

 It should still be possible to swap between colour and BW printing using the
 same mechanisms as before 1.5.2.  If this is broken, please file a bug report,
 including the gschemrc  gafrc files you used.


Thanks, that worked perfectly.

Matt
