Re: how to create custom off page symbol in pads logic ??

Thanks for your reply.let me know what is lines ?? i found some template sheet is available let me know how to create the template sheet ??

For creating custom offpage i need to create in parts option ?? how to create special symbol ?? instead of edit and copy method.

Try updating your part in the schematic; it sound like it is out of date from the changes you made in the library. 

 

FWIW - I define a CAP_0402 part and a CAP_0603 part to avoid issues in the design (sch and pcb can get out of sync; library update may change back to the default part, etc.).  If your engineer can't provide a proper size to the layout designer then he hasn't provided enough information.  I know because I'm the engineer and the designer!

Lines are non-connected things that you show on the schematic, like borders, titleblocks,stack up notes, etc.  You can just draw them on the schematic, but if you want to save them in a library then the get saved as lines.  You access them with 'Add 2D Line from Library'. 

 

Do you mean a template sheet that is opened when PADS Logic starts up?  Here is an old note that I have that I believe is still valid.

 

Logic – Startup File definition

To set the file that opens automatically when Logic is started, you need to export it <File><Export> (select all) and save it as the default file:

 

C:\Programs\9.1PADS\SDD_HOME\Settings\default.asc

 

Instructions:

    1. Set up what you want for a template design

 

    1. <File><Export>(select *.asc) and save it to:

 

<SDD_HOME>\Settings\default.asc

 

    1. < File><Export>(select *.txt) and save it to:

 

<SDD_HOME>\Settings\default.txt

 

(I don't recall why I had to save both the ASC and TXT files; it may require only one.  Let me know what you figure out)

 

I believe the only way to add off page symbols is by editing $OSR_SYMS.  You create a special symobl for $OSR_SYMS just like you create any other symbol in the SCH Decal editor.

I am sorry; I don't use Virtuoso so can't give any advice.  I thought perhaps this was an LVS question, or maybe parasitic extraction. Mostly I work with rule files and just use the GUIs to look at results.

How to Teardrop traces

Using Expedition 7.9.1

 

Have a large track which need to neck down/teardrop into a pad - how do I do this?

 

From what I see the standard settings in expedition teardrop pad-to-trace this is not what I need to do

What I need to do is trace-to-trace teardrops.

 

See attached picture of trace and pad.

how to change the Diff Pair trace widht ??

Hi ,

i set the differential pair for my design.i could not change the trace widht for assigned pair.in default i keep min trace width is 4mil and max is 25mil.if i assigned differential it is automatically assigned tracewidht as 6mil i need to change the trace width as 5.6mil how to change tracewidht and even i could not keep tracewidth 4.5 mil for inner layer.i got error how to clear it

Hi Greg,

 

as far as I know there is no way to do this with the teardrop option.

 

 

1) What you can do is to segment the tarce and progressively use smaller trace widths.

  something like the picture

 

2) add a tinny area fill of a triangual shape to the traces

Hope this helps

You can't set the trace widths of a diff. pair to be less than the design rules. So somewhere in your settings you have a rule for a 6 mil trace width for those nets, and that is what needs to be fixed. I recommend creating a class for the nets in each of the different values of diff. pairs (90 ohms, 100 ohms, etc.) just to set the trace width to the right value. Then you should be able to set the width and spacing in the dialog box you show.

Hello

 

Have you set your Styleset to display the Additional Component?

This will be under the Connector - Decoration - Related Entities - Additional Component - Symbols - set a default.

If you have set that and it does not work, you may need to Apply Styles or Update - Border.

If those actions do not resolve the issue, then let's see if other ideas appear. After which I suggest logging an SR on SupportNet.

Regards,

Pat

If you cannot change the layer definition to maximum layers in PADS Viewer, you can install the PADS Full version , open it in demonstration mode, change to maximum layer mode and import the ASCII file, but the only drawback is that the installation size is huge(>2GB).

 

or a simpler solution, ask the source of the ASCII file to send you the PADS PCB file.

Hi!

 

I can't see the picture, you've inserted, but unfortunately I cant find the related entities, in the style sets. As you can see in the picture below, I don't have such option. I don't know how is that possible, maybe I have an older version of Vesys?

Efm의 모든 Object에는 클릭, 더블클릭 등의 이벤트를 연결할 수 있습니다.

 

Efm에 text object를 놓고 적절한 표현을 한 다음, 이벤트 중 EventClick 또는 EventDblClick 에 아래와 같은 구문을 넣는 방법이 유력해 보입니다.

 

예를 들어 특정 text를 마우스로 클릭할 때에 인터넷 익스플로러를 여는 hyperlink를 만든다면 해당 text object의 EventClick에 아래의 구문을 넣는 방식이 될 것입니다.

 

    Dim oShell

    Set oShell = CreateObject("WScript.Shell")

   

    oShell.Run  "%SystemRoot%\explorer " & "http://www.google.com"

 

XpeditionPCB에 어떤 행위를 가하거나 정보를 뽑아내는 구문을 넣고자 할 때에도 위와 같은 방법으로 필요한 Event 함수에 해당 구문을 넣어 볼 수 있습니다.

       i simulated a layout with p2040 and 5ddr3(4+1ecc) in 1333 mbps i found that all the nets are passing and only dqs is listed in violation dqs 0,1,2,3 are getting failed

and 4,5,6,7 are passing what would be the error

Capture.JPG

i had obseved all the lines are routed with equal length with respect to the corresponding data lines

when i examined the layout

all the length matching is perfect what would be the reason for this failure?

Hi Laszlo

Sorry about the picture - not sure why that did not appear correctly.

However, now that you have mentioned your tool is VeSys, the answer is sorry - the Related Entity item in Styleset is only available in the Capital toolset.

In fact, Additional Component tab is not available inside the Connector, thus I am not sure how you are adding the "Sub-Component" for the Connector.

Please let me know how the sub-component is being handled, or perhaps log an SR on SupportNet for more detailed followup.

Pat

Hello!

 

I'm adding the sub-component for the connector in the "Component Maintenance dialog", as part of the housing, like in the picture below. This way I get the "extra" table in the harness design, but I'm sure, it's possible somehow, to add the symbol too. In the second picture, its visible, that I have an "Additional Component table" but I don't have an additional component symbol, and I can't add Symbols.
