Differential pairs exiting/entering IC's

$
0
0

Hello,

 

I'm routing all kinds of different differential pairs (ethernet, PCIe, SATA, HDMI) but somehow I can't seem to let them normally enter or exit an IC.

I think this is due to the differential separation required, which differs per IC pitch.

For example, on top/bottom layers I use 0.18mm traces with 0.13mm gap to achieve 100R diff impedance, but the pins on which they need to connect are 1mm separated.

I tried playing with the constraint manager editing separation distance, distance to convergence and convergence tolerance, but nothing seems to solve it. Whenever I try to put a trace it says 'Multi plow failed'.

 

Anyone have any idea how to solve this?


Bus Ripper symbols point in the wrong direction + non-orthogonal segments

$

In the process of moving some stuff around, some nets off of a bus got disconnected.

 

Restoring the connections result in the old style (diamond shaped) bus ripper symbol pointing in the wrong direction. They do re-connect, but it looks stupid.

 

Attempts to flip the symbol only result in other weirdness like stubs extending out in the wrong direction. When I pull the stub back to the net the bus ripper symbol points in the wrong direction again.

 

Not to be deterred, I deleted the nets intending to re-rip them. When I select bus and then "rip nets" I end up with an error message:

 

"Nets can't be ripped from a non-orthogonal segment."

 

I wasn't able to locate a good definition of that statement.

 

Any advice / hints appreciated,

 

Ken

Dear all,

I have another issue with Hyperlynx SI

I advanced to module 5 of demo:EMC Analysis .I setup below circuit and adjusted clock frequency to 133MHz (as tutor told)

I observed about 15MHz skid to 150MHz on Spectrum Anaylzer.

I adjusted frequency to 175 MHz and results can be found on below image :

I stucked here again

Any suggestions please?

Loss Snap to grid when Edit an existing Plane Shape

Hi, when i try to edit an Existing Plane Shape , for example i need to reduce a shape, moving a segment 45 degrees, this shape goes out of snap.

If i move only a sigle point, by click on intersection points, all ok.

If i move a 45 degree segment, by click on medium point (red point), shape goes out of snap grid...

In many casy , in diffent type of layout : i see that VX work too bad in Draw mode respect EE7.9.x versions...

 

Thanks in advance for other feedback, if this is a real problem or i'm using Xpedition draw mode bad.

wrong pin rotations after doing project integration in pcb

$

Hi All,

Please help.

I created a central library for a project, with cells all newly created.

However, after I do project integration into pcb, the pins of some parts become rotated.

The cells in my library are surely ok.

My pcb is a converted one from Altium (Altium -> PADS -> Expedition).

I'm not sure whether the conversion process has something to do with some settings on my pcb.

My central library did not go any conversion process, only the pcb.

 

I tried to do Project Integration in a new pcb (non-converted) and everything is ok.

Please help advise.

Thanks.Community_Admin

 

Update of @PRINTORDER fails

$
0
0

Currently we note an effect in an existing project during the update of the property @PRINTORDER which we can not explain.

We procedures as follows:

1. Generating the required PageOrder.txt

2. Invoke Tools / Update other Objects... with the settings "Properties = on", "Print Order = on", Range = Project"

3. The @PRINTORDER property of each border receives the correct page number

 

After this, the scout is able to place the correct sheet number on the border by reading the @PRINTORDER property. So far so good.

 

Then, we add a new block on the top sheet which includes new sheets. These sheets have also the same borders as the other sheets of the project, where the update of the @PRINTORDER property worked without any problems.

We did the same procedure like above:

1. Generating the required PageOrder.txt

2. Invoke Tools / Update other Objects... with the settings "Properties = on", "Print Order = on", Range = Project"

3. The @PRINTORDER property of the old borders receives the correct page number. But the @PRINTORDER property of the borders of the new sheets received nothing and are empty.

  

I checked the "Setup / Settings / Sheet Numbering" - everythink is ok.

I add a new sheet in an old block. This sheet receives the correct value and is assigned to the @PRINTORDER property.

There is only the problem with new blocks and its underlying sheets.

Have anybody any idea and can explain this behavior?

I must admit I'm confused why the concern?

I was impressed with myself getting a nice high level but as far as I know my boss doesn't check this to give me a promotion.

Why the concern?

Well, when Mentor is introducing a new Communities platform then I want that everything works.

But since the update its not working...

It's now the second time the user progress was erased.

I know the progress is not the important thing, but is this a reason to say we don't care about it?

Good evening everyone

I recently installed the PADS Layout VX version 1.2, everything works correctly, but the VIEW / PADS 3D menu l 'option is not enabled and I can not use it.

Have I committed some installation error?

How do I enable it?

Thank you and good evening.

Hi Cristian,

 

Are you sure that during the installation you chose the PADS 3D Plug in item in the installer (Product Selection tab) as I believe it is not selected by default?

 

Cheers

Cadra License not available

We got two new computers to replace two older ones. We reinstalled CADRA21 on both PCs. However, when running the software, we are getting License not Available. What do we need to do to get this resolved?

If your PADS Standard or Standard Plus seat is on maintenance, new licenses are available on SupportNet to enable the new PADS 3D functionality in PADS VX.1.2. The PADS 3D software is listed as a separate product ('PADS 3D Plug-in') during the install; selecting 'PADS Layout' alone will NOT deliver the PADS 3D functionality.

Follow these steps carefully to enable the PADS 3D functionality:

  1. Download your new license file from SupportNet
  2. Install new licenses (feature names are 'm3dplugin' and m3dpdfoutput'): 
    • Mobile compute/local licenses: Refer to TechNote MG59461
    • Network/floating licenses*: Refer to TechNote MG59655 (license server administrator only)
  3. Test to see if the View>PADS 3D menu item is available. If not, continue below...
  4. Start the PADS VX.1.2 installation again (double-click PADSVX.1.2_mib.exe)
  5. When you arrive at the 'Confirm Installation Choices', the 'PADS 3D Plug-in' product should be in the list (this indicates the PADS 3D licenses have been detected).
  6. Click 'Install' to install the PADS 3D Plug-in.

* Clients to the license server: No license install is required; the PADS 3D licenses need to be installed by your System Administrator. Once complete, continue from step 3.

Hi Rajesh-

 

According to "Methods for Correcting Pin Swapping" in the xRC manual (calbr_xrc_useref.pdf), the only restrictions are "a layout-based flow and the pins are on primitives or the top circuit only".

 

If this doesn't match your setup, there are three other methods listed in that section that could be helpful.

 

Best regards-

 

Sam.

Plow Interactive to any angle smt pads

$

Hi, in a project I had to place a so-dimm connector at 55 -degree.

Pads 12x60th.

With trace/clearance 0,15mm/0,15mm, plow interactive.

so-dimm.jpg

To exit from pads, i must switch by press "F3" in any angle, with option degrees set to 255, click to perform short segment, and after press F3 to return 45 degrees.

Another problem , when return to 45 degree, plow style goes to "rela time Dynamic", bad for me because i use "Hockey stick".

The question is : Why Xpedition don't perform firs segment any angle , without press F3??

With Differential pairs , this problem is more big.

Only solution is route/fun out in cell editor ??

For me PCB works bad in any angle, when i try to exit from a pads any angle.

If i try to route between two pads or a 0603 resistor placed 255 degrees, pcb editor works fine and trace pass center with any angle segment, without press F3.

 

Thank in advance

Paste from layout clipboard results in the pasted silkscreen and assembly refdes's moved

Hoping someone can help me with this.

 

I paste from the layout clipboard an entire circuit that contains about 40 components.  The components and traces are pasted correctly, however:

 

1.  The refdes's in the assembly layer in the pasted circuit are now bigger than I had set them to in the copied circuit.

2.  Same thing with the refdes's in the silkscreen.

3.  I created plane obstructs underneath the copied circuit.  When I paste the copied circuit, the pasted circuit does not have the plane obstructs.
