Layer Toggle

Have you ever wanted to quickly switch to a different layer while routing? Of course you have, F4... Duh!

 

What if you want to switch to a layer that isn't part of your current layer pair, Lx<Enter>... I hate that.

 

Several years ago I asked PADS to give us access to the currently active layer property, and a few versions later they actually did it. For various reasons I haven't put much effort into using it until this morning. I have this macro mapped to Alt+F4

 

current_layer = Application.ActiveDocument.ActiveLayer

if current_layer >= Application.ActiveDocument.ElectricalLayerCount then

  Application.ActiveDocument.ActiveLayer = 1

else

  Application.ActiveDocument.ActiveLayer = current_layer + 1

end if

 

It will toggle to the next electrical layer and roll back to L1 after hitting the electrical layer count... I like that

Using this macro in conjunction with the ZC modeless setting will display the layers one at a time, in succession... I like that too

 

PS

I actually have it mapped to Alt+4 also... because I mapped all the F keys to there corresponding number key so I don't need to stretch so far.

L-Edit keyboard shortcut key for drawing boxes

Hello,

 

I am working with L-Edit Win64 15.23.  I very frequently switch from selection mode after drawing a box by hitting the Esc button and then go back to drawing boxes but hate to have to click on the drawing boxes button on the toolbar.  Is there a way to get a keyboard shortcut key so that I can toggle from selection mode to drawing boxes without using the mouse?  Seems like a very basic and simple feature but I looked in Setup --> Application --> Keyboard and while there are many features that can be assigned to a keyboard shortcut key, there is nothing for drawing boxes.

 

Is there anything that can be done?

 

Thank you!

DxDesigner and QUESTA ADMS Compatibility

Hi, I'm a newbie to the PADS community. I have been given a task to generate a new mixed signal circuit using DxDesigner.  For simulation of this circuit, we are supposed to use Questa ADMS. However, i doubt that whether DxDesigner and Questa ADMS are compatible? Is it possible to use DxDesigner as your Data Entry Software and Questa ADMS as your simulation tool?

 

If yes, Please guide me step by step.

Symbol Editor in xDX Designer VX.1.1

October 1, 2015, 2:23 pm

I am a new user of xDX designer VX.1.1 which I have as a PADS netlist flow. I do not have a PADS layout tool.

 

I have successfully linked a sample netlist library to my project but now I would like to add and/or edit the schematic symbols. I have

several components that would need added, but I just want to create symbols that a layout service bureau will complete with cells, padstacks etc..

 

So when I go to FILE-- NEW --- Library Symbol (or Local Symbol) the Symbol Editor tool

opens. But the Symbol Editor window is all gray and has no functionality.

 

So my questions are the following:

 

1) Is there another way to create/edit symbols in xDX designer? Am I doing it correctly?

2) Do I have to have a license for the PADS layout tool in order to create symbols?

 

Thank you for your time.

PADS Logic: "Reached Part-Type database limit"

Has anyone seen or know the reason why a dialog box stating "Reached part type database limit" would be shown?  This wouldn't be the same as running in demo mode where you typically see the "exceeding limits, will now run in demo mode" saying.  Story being a user was working in a larger file (roughly 450k) and before they knew what happened, they tried to reopen and seen the dialog box and wasn't able to open the design.  The program went into deep thinking and proceeded to shutdown.  This happens every time any user tried to open this file...as well as the file appearing around 65k now.  So, in my estimation there must have been some corrupting that occurred and now that file is kaput?  Thoughts or ideas on how to fix whatever s broken?  My best alternative would be to back up to Friday's version and go from there. 

 

Thanks in advance.

Ho to generate reusable Blocks for other projects

Hi everyone,

 

I just cant find the information I need, so here I go: we are using DxDesigner for schematics capture (hope this is the right place to ask). Within one project, I designed a block that shall be reused several times, and got that working fine. Now I want to go one step further: we need the same block in other projects too, but I'm not sure how to get this done.

 

The first step might be just getting the schematics block to be reused, later on we might want to reuse layout too, but that is not yet important. So my question is whether anyone can please give me a short how-to or name a appropriate document.

 

Thank you very much in advance,

 

Kind regards

Hello everyone,

 

I am attempting to adjust the B size border from the default 2x4 sections to be 5x10 sections. I have been completely unsuccessful and could use some guidance. As it is the borders in PADS VX 1.1 seem to be scaled very large compared to the actual paper size, the B size block measures 2" x 6" when I print it.

 

Thanks

Hello to All,

 

When I try to make a forward annotation from DxDesigner to PADS Layout (DxDesigner is closed) it shows me an error: Can not open DxDesigner project.

 

If I have my schematic opened manually it connects, but when I press "Forward to PCB" it shows the following info:

pcb: Note 5996: Using Config File C:\MentorGraphics\9.5PADS\SDD_HOME\standard\pads95.cfg

pcb: Warning 5720: Check PSDB.err for VIEWBASE messages

Errors 1, Failures 0, Fatals 0, Internals 0

 

viewbase: Error 222: Error - Could not find WIR file PSDB.1.

 

(PSDB it is name of the Project)

 

I cannot understand what is the problem and how to solve it.

Can somebody help me please?

Comparing ODB++ Files -

Does anyone know of a tool or method to be able to compare 2 different ODB++ files against each other?

 

We have been using gerbers since the dark ages and the PCB Design team is finally moving towards ODB++ as the deliverable but, there are request to:

  • Minimally be able to compare Rev A ODB++ vs Rev B via a graphical overlay
  • Best scenario would be intelligently compare (functions to show differences)

 

We are aware of the inside compare , available smart utilities in Expedition and we currently have Gerbtool and Valor also.

 

Its preferred by Engineering to not have to use a full seat of Valor or Expedition to do this final review.

 

Thanks and direct emails are welcome.

Hello

 

I have to create a project in xDX Designer using PADS VX that must be editable in PADS9.5. I understand that constraints file (cns) and PCB configuration file (cfg) should be following: pads95.cns and pads95.cfg. I am able to create netlist to layout correctly but the PADS 9.5 user can't open schematic. One issue that is seen is error Unable to open iCDB connection. When user try to repair project in iCDB Project Backup tool he receive following error information: Repair project error [Invalid database location specified]. How to solve this issue?

alphanumeric pin numbered part in Logic

I am trying to figure out how to setup a symbol in PADS Logic that uses alphanumeric pin numbering, and I keep getting an error that reads.

 

“Error: PCB decal RJ45_10GANG not valid for part with pin mapping - Non-numeric pin number A1..”

 

On the PADS Layout side this doesn’t seem to be a problem.  This schematic was originally created in OrCAD and converted to PADs Logic.  This part must have worked using OrCAD because it’s in a layout with all of its routing complete.  

 

Looking for the correct way to create an alphanumeric pin numbered part in Logic.

xDxdesigner Variant Manager Template file location ?

When I create a Variant for a design, It creates some ".cfg" files in the folder.

I then need to change the settings because it is not what I need , Specifically the "VmgrLdataGrid.cfg"

 

is there a place where I can place a "template"  VmgrLdataGrid  that will be used for all subsequent designs as a default.

 

it is very inconvenient to have to change settings every time I add variants to a design.

Also I can't always remember what I have to do or what file it is to copy.

I do uses variants, but not all that often.

Has anyone found that the context menu is lost when trying to implement IXLogicAction and IXApplicationAction in the same custom action?  If so has anyone found a solution around this?  More details: I implemented both actions and when using the context menu on a logic diagram object the custom action is lost.  If I remove the IXApplicationAction and only use IXLogicAction the context menu is present.

Jiffy Splice

Hello,

 

What is the best way to deal with jiffy splices? They are a connected male and female terminals covered by a sleeve. As a connector I always have to create a zero length bundle to show both wires coming in from either side. As a splice the terminals could be additional components but you can't assign the male/female terminal to its designated wire. This would probably create an issue down the line when running it through TVM as the terminals get terminated like any other wire.

 

Any ideas?

 

Thanks!

Calibre nmLVS with custom plate capacitance. How to ignore cap in schematic?

November 16, 2015, 1:40 pm

Hello! I'm a newbie to Calibre nmLVS. In the layout of my cell, I made a custom plate capacitance with 2 metal layers. This capacitance is between an internal node (b) and the output pin (out). In my schematic, I put a "cap" from analogLib to represent this capacitance, but when I run LVS it fails (because it sees the cap in the source, but not a corresponding instance in layout).

Do you know how I can have a positive check with LVS? I tried by changing "cap" to "pcapacitor" hoping that LVS would ignore that, but I have the same error.

 

Thank you very much!
