Problem in orcad

S

Guest
For the first time i used the hierarchic structure in orcad but i can't
create the netlist for the layout. I have an error message:

ERROR [MNL0022] Unable to Open MNL Output File -
ERROR [NET0011] Netlist failed or may be unusable.

If i delete the subcircuit, i can create the netlist without any problem.
What can i do?
Thanks

I love to cook with wine. Sometimes I even put it in the food.

It sounds like you have an error in the schematic that is screwing up
the netlist. Try running the "Design Rule Check" it should give you an
indication of where the error is.

Just a comment: the last couple new versions of Orcad (9 & 10) have
been terrible. In 9 the rubber banding of signals when ou move a part
got screwed up, then in 10 it randomly drops connection dots all over
the place. And here is the killer, twice now I have found errors in
the netlist generated for the PCB layout. The connection looked fine
in the schematic, and when I generated the netleist a second time the
error was fixed. Fortunately my layout guy was sharp enough to wonder
why there was an op-amp with only one of the inputs connected. Lately
the things I have been working on have been small enough that I can
take a couple hours to check the netlist manually, but soon I am going
to have to do a large board and an very worried about the integrity of
the netlist.

So I am looking around for new schematic tools. Does anybody have
recomendations? I am considering Protel, just because I haven't heard
anybody complain about it yet.

Isn't it amazing? Cadence/OrCAD is intent on dropping the old
original MicroSim Schematics that work so well with PSpice and forcing
everyone over to Capture.

But the Capture developers must be the dumbest creatures on three
wheels... they keep making Capture more and more of a kludge.

We got an eval version of Protel just to check a sub-contractor's schematic
and pcb files.

It looks like a truly dreadful port of a DOS app. You can't click on
anything and pull up properties or whatever. I susepect it all has to be
done from menus that you have to learn. In short it stinks.

In comparison, Powerpcb ( now called PADS again in its latest version btw )
is a true *dream* to use. Another subbie provides Powerlogic and Powerpcb
files and I find them very easy to edit and screen capture ( since we also
only have the eval copy ) so as to feed info back to them.

p.s. anyone ever remember when you were meant to 'hand check' the netlist ?

What's in the toplevel? What's in the subcircuit? Is the subcircuit
a hierarchical block?

Since this sounds like Capture (gag me with a spoon), please post the
DSN, etc., files on alt.binaries.schematics.electronic

Hello Ethan,

I switched to Cadsoft Eagle. Nicely integrated editor and layout
package. The downside is that Orcad is still widely used so the only way
to exchange data with layouters is a netlist. That gets in the way when
they ask for a minor circuit change which you'll have to hand-edit in later.

I used to design in Orcad but after they changed to Windows I did not
like it much anymore, plus it has gotten really expensive for a
schematic editor.

Another case of outsourcing?
