Protel netlist outputs

Simon,
Export 6 or 7 different formats of what?
It has to be a change or netlist of some sorts if it will
transfer changes and differences to a PCB file from a schematic!
If there are no changes carried over from the schematic to the
PCB, then the board is electrically correct, a simple enough
check.

If Protel format 1.0 means anything the same as it did in
P99SE, is that not a netlist format? There were Protel 1 and 2
netlist formats in P99SE.

Protel 2004 doesn't use netlists anymore so its no wonder you
can't get one.
It will of course export 6 or 7 different formats including
VHDL and Protel
format 1.0

My boss wants to proof circuits with component/net netlists in a
condensed readable fashion, however Protel 2004 only produces one, as
far as I can see, and he doesn't like the format.

Can I generate a different ascii netlist format?

Ivan,
Will your boss sign off on a schematic? Once the schematic is
checked and signed off, output the netlist and read it into the
PCB, during the input process generate a report of the netlist
input changes, voila you have a discrepancies report. (works well
in P99SE, not sure the equivalent report generation of a netlist
input exists in DXP).

Actually Simon,
DXP 2004 has not less than 12 add-on utilities for outputting
differing formats of netlists. So now I really don't understand
your comments after doing a little checking today. They have 12
different netlist output utilities available on their website for
downloading and plugging into DXP 2004.

It was very informative to hear Brad and Simon discuss netlists. I
have learned a lot.

Here's a question to put out there:

I remember using PADS Logic/PCB for DOS years ago and I was able to
generate not only a net to components netlist, but a component to nets
cross reference listing.
ie.
Q1 - 1 Net A001 Q1 - 2 Net L007 Q1 - 3 Net GND

C7 - 1 Net H090 C7 - 2 Net GND

etc.

Is there a program that can do this out there? I have experimented
with all the netlisters available on the Protel website, but non do
this.....

Just curious.

Ivan

Something like this is the schematic analysis output format from
Vutrax, and can also be generated from finished artworks along
with the more conventional forms of nestlist.

Ok, thanks for the clarification Simon. At first I thought
something was drastically different in DXP and I was unaware of
it. But they still will do a netlist, or I am betting that when
you do update PCB, you can still generate a report of the changes
being noted for the PCB. Same as I currently do with P99SE. After
reading in the netlist, you are essentially in the Update PCB
Synchronizer, with the list of changes on the screen, right click
on the list, generate a report of the changes. Some are always
non-circuit issues like Fiducials, test points or something else
that isn't found in a schematic.

By the way, I cannot recall exactly what it is at the moment
but ERC checking has one very big hole that it doesn't check for
in Protel. Damn brain isn't working so well this morning but I
know there is one check that I would have them add in to make it
more complete, in the mean time it is not bad but only about 95%
complete. Maybe it has even been added into DXP already, aaahhh I
remember, checking for continuity and connection across ports and
netnames, also single node nets regardless of pin type and
whether you connected a wire and ran it to a port. Check that all
the names match and that there is at least one connection across
them if they exist. Still not foolproof though because there is
no way for it to know there should be X number of connections on
a net in total. OrCAD used to do a net or port name connectivity
dump, I used to use it to try and find slightly misspelled net or
port names because they would usually come up right close
together on the report. They also would show a listing of
netnames where you had connected dissimilar netnames together
intentionally.

However, as far as Ivan's enquiry goes, check the Schematic
thoroughly, do the ERCs, update to the PCB, generate a report of
the synchronizer updates, have the boss sign off on the
schematic, the ERC check, then an update PCB change report and a
DRC report. At our shop the designers add notes to either the ERC
or the netlist/synchronizer report, indicating what the issues
are that generated any message. (i.e. The update report is trying
to delete a fiducial. we add a handwritten note stating that
"fiducials are not found in the schematic". Or, "Shorting
connection added to implement Star Point Ground", etc. )

After all of this our design manager signs off on our designs
and keeps the design paperwork including these various checking
reports in a file cabinet. For too many years he had designers
telling him things were fine and dandy, now he holds this
paperwork over your head and if anything is wrong it had better
have been something that slipped through the checking without
being caught for some reason. Then we adapt our checking and
check lists to cover any new found issues. If you touched the
board after the checks and cause any problems, he will have you
by the short and curlies. He is not a nice guy but so far I
managed to stay on his good side, others have not and I see how
they are treated by him. I just plain don't want to be there, I
don't need that aggravation in my life.

but a default installation for Protel 2004 SP2 will output
edif for pcb
Multiwire
pcad for pcb
cupl netlist
Protel (1)
VHDL file
Xspice.

that's 7.. and I only had to use two hands to count them :)
There may be 12 on their web site.. but I don't use Protel add
ons unless I
have a need

The actual protel 1 and Protel 2 formats (so I added a .0 not a
big deal)
are obsolete. They haven't been necessary for PCB design since
Protel 99SE
so it really isn't surprising that they don't exist any more...
I myself
never noticed they were gone... but it could make it difficult
to do a
netlist compare... something
I've done from time to time to satisfy a customer on rear
occasions.
I also wont mix and match packages.. so no Protel / Orcad
mixes. Neither
companies really want you to use the others package so don't
make it
entirely seamless. On the odd occasions I've had to convert I
spend days
just checking that everything has come thru seamlessly so I
always try to
avoid that.


But I have satisfied myself over the years that if the PCB DRC
has zero
errors, and the Schematic ERC has zero errors then the result
is exactly
what I suspect. Any warnings are individually approved. I
also flag any
unconnected pin on the schematic and verify each and every one.
I have
never had a board that was anything less than what was on the
schematic.
For this reason I don't usually do a netlist compare and I have
full
confidence in Protels results. I also flag any potential poor
warning
message and feed it back to Protel in the hope something useful
replaces it.
I would also stop using Protel if I lost any confidence in the
ERC and DRC.
This together with a well designed schematic that is easy to
read and easy
to understand and hence easy to locate errors makes the system
foolproof...
but occasionally I've worn the fools hat <:)


And that is why I have I don't generate netlists.
