These components are from the libraries MentorGraphics\Parts\Caps\Cap and
MentorGraphics\Parts\Res\RES.  Perhaps, I'm using the wrong libraries?

However, DxDesigner will only let me assign numeric values; I can have 1.2, but
I can't have 1.2K or 1.2uF.

Now it seems to be working! I restarted DxDesigner several times, and that

Several issues with borders:
1) I created a border by modifying an existing one, deleting the
"MentorGraphics"  logo, and pasting my own bmp logo.  Looks fine in Symbol
Editor.  When border is placed on schematic, "MentorGraphics" AND my logo seem
to be laid on top of each other. (As a I pan, I'll see one or the other logo
displayed)

2) I was able to change the NAME parameter, but I can't change the YourNameHere,
date, or any other parameters.

When ever you change or add to the Properties definition file you
need to restart DxDesigner.  Mentor has not figured out how to
reread the file after a change.

I use PADS V 2007 and DxDesigner, but am interested in hearing from people who
use other tools as well. With today's high speed circuits, the design rule check
of the past is woefully inadequate. I am finding even the high speed rules
available in PADS are less than adequate. The first problem with PADS & DxD is
the method of entering rules and reviewing them. It would be nice to be able to
see all the rules at once, or at least all of a particular type (nets,class,
group, conditional).

Setting rules, routing (especially manual, and remember, even if you auto-route
you are likely to need to edit which usually means manual routing), and checking
of the results is a daunting task. Even if the tool has the ability to write the
rules that will be necessary to assure a working board you must have a way to
check that the rules themselves are correct. Presently checking the rules
entails output of an ascii file or using the dialogue boxes in PADS and/or DxD
to review them. This is woefully inadequate, time consuming, and error prone.
The output to an ASCII file would be much improved if it were to a spreadsheet.
I am aware that you could use VB to do that but have not had the time to develop
that.

But I am finding the present paradigm is outdated. Almost every board has
differential pairs, and usually several requiring different parameters, that
must also be kept away from each other, other nets as well, and by the way be
matched to themselves, each other, and between groups and often are not simply a
source and load but a serial connection of multiple loads that must be matched
and conform to the width and space rules as well.

Is anybody finding it possible to write all the rules they need to assure the
layout conforms to the design parameters using DxD and PADS (or another set of
tools). If you are, are you able to assure the differential pair has the correct
gap throughout ( never too little or too much) and that it is spaced properly to
adjacent nets. How do you pull that off?

I guess I duck the question entirely by using a layout house that never
autoroutes, and understands layout rules and transmission line effects better
than most of the engineers I work with.  I realize that's not a helpful answer.

On one occasion, I needed to have one of our existing layouts updated by a PCB
layout engineer who used autorouting. It took weeks to enter all the rules
needed to support the change, which consisted of adding diagnostic LEDs.  The
change should have taken a few hours, at most.

I've also seen designs in which a high-speed processor was current starved
because the ground had been necked down to 3 mils in exactly one spot because it
had been autorouted.

As you can see, I'm not a fan of autorouters.

..and there are valid reasons not to be a fan of autorouting.

But I am not really talking about autorouting, I am talking about autochecking
the design. Whether the board is manually routed or autorouted, it makes no
difference, the layout engineer will check the layout against the design rules
to make sure it conforms to design intent. Surely your layout engineers are not
manually checking the board, that would be both time consuming and error prone.

For example, I have a small backplane board that is entirely 100 ohm
differential impedance pairs. The stackup we are using requires 8 mil line and 9
mil space with 24 mils of space to the next pair. Typically you set the default
minimum line and space and the DRC will flag places that do not conform.

But we are also concerned about MAXIMUM distance as well as minimum on the
differential pairs (so that the space is maintained throughout). We also are
concerned about crosstalk we have a minimum distance to maintain between pairs.
ANd of course we also want to check that the pairs are matched to each other in
length. On other boards we also to match between pairs and between groups of
pairs. And that is only the tip of the iceberg of rules.

Obviously, the CAD system used needs to have the capability of setting and
checking all the various rules as well. But as the design rules become more
complex, it becomes even more important to review the rules so you are confident
the rules are set properly, otherwise you are shooting yourself in the foot ( or
maybe the head).

Hi,

Sometimes I'll have a jack with a REFDES of Jx and sometimes I'll have a header
with a REFDES of Ex.  Schematically they are the same and I would like to use
one symbol for both, but DxDesigner won't let me change the property on the
schematic from "J?" to "E?".  Is there some way of doing this?

My problem is that when I initially place the symbol, it will default to “J?”. I can go and change it to J3 or E4 or FRED6, but I can’t change it to E? or FRED?; it won’t accept the “?”.  I believe there’s probably something I can change in those cryptic “regular expressions” in the Property Definition Editor…

If you are talking about when you initially place a symbol, you need to change the REFDES prefix in the symbol.  But, once it's placed, you should be able to change the REFDES to anything you want, J or E or FRED if you want.  I'm not sure if you have to do anything special in the viewdraw.ini file though.  I do the following:

Hi Austin,

I’m just migrating from OrCad, so I’m working from that frame of reference. I’ve just jumped into creating a schematic figuring I’d ask questions along the way.

I don’t want to (or need to) assign REFDESs until my schematic’s done.  Then (I assume, I haven’t gotten there yet) at some point  DxDesigner will assign REFDESs -(I suppose I should look that up).  I don’t want to have separate symbols, one for jacks (J?), one for plugs (P?), one for configuration headers (E?) etc. since they are schematically (and in many cases, physically) the same.

The specific situation I’ve encountered: I’ve got a 6 pin Microfit jack; that should be J?.  I also have a 6 pin dual row header for jumpers; that should be E?.  They’ll have different packages.

Does this make sense?

Thanks,

Hi Barry,

Why do you want to change it to a FRED??  Wouldn't you want to change it to FRED6?

I assume you are copying it or something?  Yes, it then will default back to the original default REFDES.  But, as I said, you can change that by editing the symbol and changing the REFDES default attribute.  And, by editing the symbol, I mean the symbol, not the symbol that's ON the schematic.

For flat designs you want to create an Annotate type symbol.  Add the XREF attribute

 

For heirarchy, you need to use Pin type symbols, and also add the XREF attribute to specify location. 

 

There is a XREF utility for flat designs in 2005 and Scout for heirarchy.  For 2007 the utility to XREF is Scout, a more powerful cross referencer.

Hi Robin,

 

In DxD, unlike OrCAD, you don't need to specifically add off-sheet connection symbols to a net for it to go between sheets.  But, what I think you are asking is done with a utility called "scout".

Hi Austin,

Forgive my ignorance, I’m new at this, but I thought the PKG_TYPE attribute defines the PCB footprint, no?  And none of the connectors in the Mentor-supplied libraries even have a DEVICE attribute. 

The way I’ve always worked (in OrCad) is to just place, say, a bunch of capacitors.  I would use the same symbol for all my caps (since they all LOOK the same on a schematic).  Then I would assign the particular PCB footprint to the individual caps as required.   Shouldn’t the same methodology work with DxDesigner?

But I digress.  The issue is: Why can’t I assign a different prefix to a symbol.  If what you say is true, then I’ll have to change my thinking and just have different symbols for different types of connectors.

Hi Barry,

The DEVICE attribute is important, as it defines the PCB footprint.  So, for any part that has a different footprint (and different part number), you typically want it to have a different device.  The exception is alternate footprints, say, for an 0402 where one is for "normal" placement, and one on the back side of BGAs.

I typically draw my schematic symbols to match closely my connectors physical connection layout.  It makes debug MUCH easier, and provides better documentation for people trying to figure out what the circuit does, and how to hook to the connector.  DxD has "better" drawing capabilities than OrCAD that allow me to make some very annotated symbols.  I would make the schematic symbol for a 6 pin Microfit jack different than that for a 6 pin dual row header.  For any part number, I use a different symbol.  But, that's just my methodology.  I'm not sure how you would do your methodology, and get a good BOM or get the correct footprints.

So, if you aren't assigning the REFDESs yet, you would want to edit the symbol REFDES default prefix to be what it is you want it to be.

Austin

Hi Barry,

Why do you want to change it to a FRED??  Wouldn't you want to change it to FRED6?

I assume you are copying it or something?  Yes, it then will default back to the original default REFDES.  But, as I said, you can change that by editing the symbol and changing the REFDES default attribute.  And, by editing the symbol, I mean the symbol, not the symbol that's ON the schematic.

Regards,

Austin

Hi Austin,

My problem is that when I initially place the symbol, it will default to “J?”. I can go and change it to J3 or E4 or FRED6, but I can’t change it to E? or FRED?; it won’t accept the “?”.  I believe there’s probably something I can change in those cryptic “regular expressions” in the Property Definition Editor…

Hi Barry,

If you are talking about when you initially place a symbol, you need to change the REFDES prefix in the symbol.  But, once it's placed, you should be able to change the REFDES to anything you want, J or E or FRED if you want.  I'm not sure if you have to do anything special in the viewdraw.ini file though.  I do the following:

|5.0 ATTR_PROMOTE REFDES

ATTR_RESET REFDES SYMBOL_VALUE

Regards,

Austin

Hi,

Sometimes I'll have a jack with a REFDES of Jx and sometimes I'll have a header with a REFDES of Ex. Schematically they are the same and I would like to use one symbol for both, but DxDesigner won't let me change the property on the schematic from "J?" to "E?". Is there some way of doing this?

Thanks,
Barry

For resistors, I tried DEVICE = RES; for caps, DEVICE=CAP.  Is that ok? Same error. I think I mentioned this somewhere (can’t keep track anymore), but I got an error message saying “Illegal length 0”.  Kind of implies that something is not reading my attributes correctly?

Not sure if this is your problem, but you MUST have DEVICE set.

Hi,

When I run PCB Interface/Assign Reference Designators, I get "Bad Property Value" for PKG_TYPE and DEVICE for my resistors and capacitors where I've set PKG_TYPE 0603, nothing for DEVICE. What's wrong?

Thanks,

Barry

Hi Barry,

�

You can post the symbol to the list.� That is, if it's in a text file in your version of DxD.� I don't know how you "share" symbols with the new and (cough, cough) improved binary data files...

Best Regards,

Hi,

When I run PCB Interface/Assign Reference Designators, I get "Bad Property Value" for PKG_TYPE and DEVICE for my resistors and capacitors where I've set PKG_TYPE 0603, nothing for DEVICE. What's wrong?

Thanks,

Barry

It says "Illegal length 0" even though I have values for DEVICE and PKG_TYPE

Hi all,
I�m starting to work with Mentor Expedition and have a beginner question. I open
a project with DxDesigner and from then I open Library Maneger and create a new
part. To update the part view tab to view my new part I have to close and reopen
DxDesigner. Is there another way to update the part's list in part view?
Thank you for any help.
Regards,
Maia
