Orcad Viewer doesn't work

[Joerg]

Gents,

So, in order to be able to view Orcad schematics I gave Cadence all my
information, address, profession, shoe size and so on. That allowed me
to download the Myriad viewer. Tried it with various client schematics
and it always results in the same error:

"File load error: Internal library error"

What gives? Any idea how to fix this or about a better viewer?

 

[Joerg]

It's likely a *PHUT* in mouth problem You not only need the
client's schematics... you also need the client's symbol libraries and
OrCAD INI file.

Back in the DOS-Orcad days (as in, "when things still worked") I believe
one could store with lib parts embedded or not. Problem is, AFAIU Myriad
only has a file -> open option, didn't see anything where you could load
libs and stuff. What I have is *.dsn files.

Man, Eagle is so much better, the *.sch files always contain
_everything_. But Orcad is like Windows, everyone uses it for whatever
reason.

Is there an Orcad viewer that allows lib loading?

I thought the schematics were self-contained. Capture has a function
to export the components in a given schematic to a custom library.

Library error. Sounds like a set up file error or such. Did you
try
to ask THEM about it, or even perform a simple google search to
see if it is a known, already fixed problem in the EDA user world?

Web search, yes, came up with four hits. The answers essentially were
that it doesn't work.

What about simply going to their user support forum and seeing
if it is a known problem?

Couldn't get in. Possibly my firewall blocks something and it usually
has good reasons for that. Wish companies were as smart as Cadsoft which
runs all Eagle support forums in (tada!) newsserver fashion.

Sounds like a simple setup error where it is looking for a path
they hard coded into their app, when they should have put some
polling code into the install dialogs.

Yea, well, if there was at least a minor hint in the error message or
the help files as to what it expects to be there. But, only error and
abort. For some reason none of my readers for other CAD formats do that.
They just work.

What about the Capture CIS Viewer?
http://www.cadence.com/products/orcad/pages/downloads.aspx#myriad

You do need the Lib files for the custom parts.

[Joerg]

Yup. **Everything**.

As said many times before, when dealing only with honest people (who
refuse to run stolen software) there is no problem. I have had no such
issues in over five years that I use Eagle.

 

[Joerg]

Yep, Now I remember. The originating designer can generate a
self-contained OrCAD schematic that has all symbols built-in.

That how it used to be in the good old days of SDT. Tried that today, it
no work :-(

 

[Joerg]

What about the Capture CIS Viewer?
http://www.cadence.com/products/orcad/pages/downloads.aspx#myriad

That one is for converting between formats. For viewing itself they
recommend the capture viewer (Myriad).

You do need the Lib files for the custom parts.

Where do I load them to? Myriad does not have any parking structure for
libraries.

Thought you claimed everything worked _except_ Adobe Reader ?

This is not a crash, it simply refuses to eat *dsn files but was
advertised as a viewer for the software that generated them. But the
manufacturer.

Adobe Reader is different. You load a file and it completely crashes.
Interestingly, Foxit opens the same PDF file without any problems
whatsoever. Now what does that tell us?

Poor Joerg, he was born with a silver *PHUT* in his mouth.

And already suffering from old-age-syndrome... he can't cope with
anything he didn't learn to use years ago

Huh? I am always learning, often way outside my trade. Right now some
aerospace stuff.

Why the Myriad Viewer?

I just looked. Don't you want...

OrCAD Capture/OrCAD Capture CIS ViewReader ???

Isn't it "Capture" Schematics you're trying to read?

Per Cadence that one is for conversions between various file formats:

http://www.cadence.com/products/orcad/pages/downloads.aspx

Quote "You can use the Cadence® OrCAD® ViewReader to convert Viewlogic
ViewDraw designs in OrCAD Capture or OrCAD Capture CIS versions 7.2, v9,
v9.1, v9.2, v9.2.1, 10.X and 15.7"

Whereas for Myriad they say, quote "View and redline OrCAD Capture
schematics without changing the original design"

And that's not working.

AFAIK there's not an option to _not_ generate a self-contained .DSN
file- the parts are stored in the design cache, which is part of the
..DSN file. The links to the original libraries are there too, but
should not be dereferenced.

Maybe they didn't save it right:

"If you copy or move a document from one design or
library to another, you should save the destination
design or library immediately. If you do not, you may
lose data if you open the moved document in the
schematic page editor or part editor and then close the
editor without saving the document"

Also.. you are having an awful lot of problems- and Orcad is a pretty
"light" and undemanding program in a single user situation*.. can you
try it on another XP machine?

* and apparently endless trouble when you have to run the license
dongle on a virtual machine on a server. 8-(

Tried it on a netbook. Same thing. Now I was hoping that a viewer that
is advertized as such does two things: Install correctly by simply using
the auto-installer. Run the data files from software for which it was
advertized as a viewer correctly. If it's unhappy about some sort of
setup on my computer, isn't it supposed to say so?

* and apparently endless trouble when you have to run the license
dongle on a virtual machine on a server. 8-(

That's another beauty of Eagle: No stupid dongles. They simply trust
their customers. What a concept

 

[Joerg]

I have had no such issues in over five years that I use Eagle.

That's one data point.
The experience Marcus had is another.

[...]when dealing only with honest people
(who refuse to run stolen software) there is no problem.

The trick is to *assure* that.
Marcus *thought* he was safe, yet he still got screwed by Cadsoft.
Everyone has to decide for himself if he wants to roll the dice
--or just avoid Cadsoft's stuff.
I maintain that even the "legit" stuff you get from the company
is still warez.

You seem to be on a cruzade there

He wrote, quote "It happened that back then, I reused a very small part
of this schema (with copy and paste) in one of my projects and continued
to copy and paste the same part from my project into a couple of other
projects of mine later on."

I never do that, ever. That's quite similar to downloading some
executable from an unknown source and then complaining that all hell
broke loose.

 

[Joerg]

Some software isn't worth stealing.

So, have you ever tried it?

If they had a hierarchy this would be the best CAD, ever. They said V6
might have it, and if it does I will reward that by sending them a check
for an upgrade.

That Foxit doen't need as much RAM as Adobe.

No, that isn't the correct answer. You've got two more tries

PADS keeps all the part descriptions in the schematic or PCB layout.
If you change the library, the designs don't change unless you
deliberately update from the library.

Same with Eagle. If you place a part into an existing schematic where
this part already exists and you had spiffed it up a bit in the meantime
there will be a warning that it has changed. Somehow it keeps track of
this stuff.

Another nice function is that you can generate a library from all the
parts in a schematic. You wouldn't believe how many people do not back
up libraries. Every now and then there is a panicky post in one of the
Eagle newsgroups "Oh s..t! My HD croaked and my custom lib is gone!".
Then someone points to the user language program that does this forensic
extraction ... huge sigh of relief.

You're surprised? That's funny!

They are. The viewer is broken, worse than Crapture. Yes, that's possible.

Perhaps but I like to be warned.

What is an unknown source? Some day you might get Eagle symbols from a
semiconductor firm. With Eagle you can't trust those. This effictively
cripples the ability of semiconductor firms to distribute Eagle
symbols.

The bottom line is: when a company assumes all of their clients are
criminals, I don't want to be a customer.

 

[Nico Coesel]

It's likely a *PHUT* in mouth problem You not only need the
client's schematics... you also need the client's symbol libraries and
OrCAD INI file.

AFAIK: depending on the version (>version 9) the symbols are inside
the schematics file.
