Building a memory array

Hi,

how to make effectively a memory array? I have built a cell (schematic and layout). For small array, the placement can be done by manually. How to built bigger array and keep higher density? I know, the placement can be done by scripts, but I am not familiar with the AMPLE language.

 

Thanks a lot!

Graphics card on NTB (which one)

$

Hello all,

can you please help me to choose the graphics card to my new notebook... not to have a problems with performance, driver..... (or minimum)(best supported)?

 

1) I can choose the NTB with integrated graphics card on chip (HD4600.....on Intel Core i7-4810MQ) AND AMD FirePro M6100M w/2GB GDDR5

 

or

 

2) either integrated HD4600 OR.... AMD Radeon HD 8790M 2G GDDR5

 

or

 

3) without integrated graphics card .... NVIDIA Quadro K1100M w/2GB GDDR5 or NVIDIA Quadro K2100M w/2GB GDDR5 or AMD FirePro M5100 w/2GB GDDR5

 

I would prefer NTB with the option 1 but I'd like to know some experience , known issues, troubles... to better decide.

Can somebody recommend me the the best solution?

 

Many thanks

A few questions on vesys 2.0 usage

- Does vesys harness support measuring from a single reference node? See the highlighted measurements shown below (FIGURE-1),

 

 

- Can the insulation tube in vesys be denoted the same as shown in (FIGURE-1), i.e. can we have the insulation with a fill pattern?

FIGURE-1.jpg

                                   FIGURE-1

 

 

 

-   Connector table (FIGURE-2) shown below, is it possible to customize the table, i.e. change the column title and have customer specific data in one of the columns?

 

FIGURE-2.jpg

                         FIGURE-2

 

 

---  -     Terminals don’t show up in the BOM report, see the attached, how do we get the terminals listed in the BOM - (Lumen-HILUX-BOM.pdf)

 

 

 

 

 

 

 

 

 

 

 

 

 

Add via option in padstack editor is grayed out

I need to add some vias in the design.  I have a integrated project that I have done and I need to add a couple of vias for routing and pouring now.

 

The add via button is greyed out.  How do we add the additional vias?  In a old "normal" design we have full control.  Is it dictated on the front end in xDX ?

 

Thanks,

CES constraint editor - formula - bus to other signals - how to?

Hi

 

Is my formula correct for that what I want to do? see picture.

 

I work with Mentor PCB Expedition 2005.3 and CES Version 5.0

 

 

Max. lenght for all signals 177.8mm

Length matching between strobe signals 'IDE_IOR@' and 'IDE_IOW@' and data signals 'IDE_D[0-15]' Max. 11.4mm

Length matching between data signals 'IDE_D[0-15]' Max. 5.08mm

Length matching between strobe signals 'IDE_IOR@' and 'IDE_IOW@' Max. 2.54mm

 

 

Is there an other way to create the correct formula?

 

Thanks

 

Best regards

New NVIDIA Driver 320.92

$

Hello,

 

We have been working with NVIDIA on the performance issues related to their latest drivers.  At this time we validated that the driver released this week, 320.92, does have performance improvements specific to Expedition PCB.  Our results show if you use this latest driver with the Workstation App - Dynamic Streaming Global Preset, the performance is comparable with the 276.28 version of the driver.  If you compare the 276.28 Base preset to the 320.92 Workstation preset the graphics system is actually ~30% faster based on the initial evaluation we have done.

 

We continue to evaluate this driver with our suite of NVIDIA graphics hardware but at this time it appears anyone who was seeing performance issues with the latest driver should load this one and evaluate.  Please make sure you use the Workstation App - Dynamic Streaming Global Preset since it will not be remember when you load a newer driver.

 

It would also be helpful if you find success or issues with this driver, please respond to this thread.

 

Regards,

How to Specify Pressure as an Outlet?

$

Greetings,

 

I'm a new user of FloEFD and I'm running into trouble with one of my simulations.

 

Description of the Simulation:

     I am Simulating a Simple box with 2 Outlets and 3 Inlets and using air as my fluid. The Inlets have different  temperatures assigned to them and I am interested in the temperature on the outlets.

 

Problem:

 

     When I run the simulation an error occurs "Vortex crosses the pressure Opening" which make my values at the inlet in accurate due to contamination.

 

Question:

 

 

     How do I specify pressure as an Outlet instead of an Opening? is this possible with FloEFD?

 

 

Any Suggestion would be most welcome.

Thank you.

Close View via Automation in Xpedition

$
0

Hi Everyone

 

I just started with scripting so I don’t have a lot of experience with scripting. Last Friday I have been trying to find a way to close the 3D View screen via Automation.

Does anyone know if this is possible and if possible how it has to be done?  I found a way to open the 3D View with the Add PCB View button in the Window Menu, unfortunately there is no close button in that Menu, so to close the 3D View I need something else. The only way I know to close the 3D View is with the x in the upper right corner, anyone know how I can access this? 

 

What I can for example is “pcbDocObj.close” but this will close the complete Layout, but I just like to close the 3D View with the Automation.

 

So if anyone has a idea or can give me a hint how I can do this, that would be great.

 

Thx alot in advance

The State of the Mentor EE7.x Symbol and PCB Footprint Library Creation tools.

$
0
0

One of the Aberdeen reports said that (I'm  paraphrasing here) "One of the core requirements to having a robust E-CAD system  is having a good PCB library".  The Mentor library tools make this difficult.   Here are some examples:

 

  1. Mentor now has 3 symbol editors, the  New Symbol Editor, the FPGA Symbol Editor and IO Designer.  Now our librarians  need to learn at least 3 different tools to build symbols depending on the type  of part.  None of these tools can easily create a large pin count ICs (other than FPGAs and ASICs)  that can handle fractures and keep track of the pins between the fractures.  None of these tools can mine the pin data from a vendor's component specification PDF file.
  2. There are 2 cell editors, the Cell Editor (which is basically  Expedition) and the LP Wizard.  Again the librarians have to learn 2 different  tools to build cells depending on the type of cell being created.  Anything built using the LP Wizard must be brought into the Cell Editor to be finished.  More tools for the librarians to use.
  3. One of the keys to using CES is having  a good model library.  Mentor has no tools in this area that make it easy for  users to add IBIS models to the library to support CES.
  4. There are also no tools to add SystemVision models to our parts in our library.

 

All these different tools  make it much more difficult for librarians to create library parts.  In our  environment we add on average 300 parts a month to our library.  Our librarians  need one robust tool to create library parts, both in the netlist flow and the  Expedition flow.  In my opinion, because Mentor has no one group in SDD  responsible for librarian tools, all we have now is a bunch of point tools that  address certain types of parts.  Mentor needs to get organized, quit the  infighting between the different factions and quickly come up with a strategy to  address this issue.

 

Do any other companies have this problem?

 

Thanks for listening,

 

Tony

Looking for 3rd party schematic symbol editors

$

Since Mentor has chosen to ignore this area for the netlist flow, we're looking to see if there are any 3rd party schematic symbol editors out there.

 

Some key requirements:

 

Able to mine PDF component specifications to get the Pin/Pin number data.

Able to create fractured parts.

Able to check and make sure all pins are accounted for.

Able to check for duplicate pins.

 

Thanks,

Hi,

Job not compatible with current version of program

I've recently switched to a new laptop and re-installed PADS Layout, Logic, etc version 9.2.  I had 9.2 on my old laptop (both are Win7) and when I tried to open a file previously created and run on my old laptop, my new laptop gives me an error stating "Job not compatible with current version of program."  I have my hardware license key installed, but I can't even open or view the files now.

 

Any help/recommendations greatly appreciated.

 

Thank you.
