Urgent! reading problems in area v5 UB DDF files, copper

Hello

I have a very strange problem with Ultiboard.

When you read an old DDF (v5) file, it is opened and converted to ewprj...

I have no schema file (paper only version) and no netlist...

Traces of not obsolete should be changed to the more recent...

so far no problem, I inserted everything manually...

It is a Council of four layers with several areas of copper on the inner layers.

When you export data, gerber RS274X, then the weardest things happen...

Of via which must be tied to GND accompany the + 5V

I have found that while old and new checken gerberas with GCprvue...

So I checked the design:

the parameters for any copper region are correct! for example: area of copper on the inner layers are defined as follows

Inner1: Layer of GND, enable invalidation, connected to the net GND, without thermal reliefs for the via of

Inner2: + 5V layer, enable invalidation, connected to the net + 5V, not thermal of the reliefs for the through the

but during the audit, the layer of EARTH is not connected to the MASS of via, but the 5V is layer...

! There is a void in the SOIL layer while it shouldn't and the 5V layer is connected,

And the strangest thing: when you run a check of the DRC, you get all the defective connections!

When you look at the original file, after that I just opened it, then everything is ok...

Maybe this will give you a hint more:

sometimes without apparent reason, there is no more fill style in a copper box, he disappeared.

everything you see is the outline of it...

As soon as you start working on the original design, things go wrong...

Can anyone of OR extract it? This happens quite often in the design-updates to update...

I use UB version 10.0.343

the attachment are screnshots with GND (green layer) and parameters of 5V (blue layer)...

Johan

Hi, no, through the should be attributed to the net (trace) they are placed, never found any problem with this... But the good news: I finally found the problem, after many hours of research... I have already mentioned that he had more no styme filling in an area of copper number '... Well that's how I finally found the problem... On one side of the Commission, that I had to replace a 16 pin IDPS by a through hole connector 4 pole. Inside 5V layer, the original designer exceeds all the necessary tracks connect connections 5V together... One of these titles (which you don't see when the fill style is full) affected a brooch of the new via the connector hole. Thus connected to 5V, and this pin should be rectified in the updated design... which causes a short circuit... a little of these layers apparently caused through the 5V to be connected to GND on the complete picture... Which makes it very difficult to find the problem... Only after I've changed the 'no' fill fill style, I could find the connection... Can NEITHER find a way to get this problem easier? When to see the faults of DRC all around the plateau, it is difficult to see that we actually really causes the error best regards Johan

  • Analog multichannel peculiar read problem with PCI-6014 - hardware problem

    Hi all

    I see some very special behaviors with a 6014 when I do a multi-channel analog playback.  I am revamping of existing code to a customer, which implies the passing of the traditional DAQ in the DAQmx.  Traditional DAQ does not use a system based on the tasks, my client was in the process of reading clocked by the software for only one channel at a time, depending on what signal was of interest to both.  (application is a series of tests on a control PCB who will interface with some hardware, checking the answers and tensions and others)

    When I rewrote the application using DAQmx, I created a single task that contains all of the analog inputs of the map (AI0:15).  When I am interested in a particular signal, I indexed the channel since the reading chart data.  The strings that contain the actual data are 0, 1, 3, 4, 5, 6, 7, 13, 14 and 15.  All channels are NRSE.

    One of the signals of interest lights AI7.

    When I connect the AI7 signal with an oscilloscope, I read 2.5V - which is exactly what I expect to see.

    When I read AI7 using MAX, I read 2.5V.

    When I read AI7 by itself using a single channel DAQmx reading (i.e. 1 Samp 1Chan or 1Chan N Samp), I read 2.5V.

    When I read AI7 simultaneously with all the channels that have a greater number of channel (i.e. AI8-15), I read 2.5V.

    When I read AI7 simultaneously with any channel that carries a lower channel number (i.e. AI0-6), I read 2.34V.

    ?????

    For example, if I read AI0:15, I read 2.34V on AI7.  If I read AI0:7, I read 2.34V.  If I read AI7:15, I read 2.5V.  If I read AI7:10, I read 2.5V.  If I read AI6:7, I read 2.34V.  And so on.  Any combination of playback channel which includes results AI0 AI1, AI2, AI3, AI4, AI5 or AI6 during a misreading on AI7.

    All channels read because they are supposed to, no matter what channel is included in the job.  AI7 is the only one that illustrates this behavior.

    I wrote code for the acquisition of data for 10 years now and I have never seen anything like this before. The behavior is consistent.  I am sure that it is a hardware problem with the Special Commission that I use.  That's the advice of my customer, I don't know when they bought it, but I think they have had for years.  I doubt that ever, it has been calibrated.

    I guess it's more I'm curious than anything else - what on earth would cause this behavior?

    I'll tell my client to replace the card, if really I just asked my own knowledge.

  • I have to remove the duplicate files, but having problems by selecting more than one file in the player at the time.

    I have to remove the duplicate files, but having problems by selecting more than one file in the player at the time. How can I select multiple files at the same time so I can just delete them. I used to be able to do this in previous versions of Media Player, but this function seems now blocked or unavailable. The problem is this: through previous use of media player, it plays all my multimedia files several times whenever a device support has been added. He would try to save the files on my main drive, but since there is not enough room this would save the files somewhere else. This happened several times, I suppose, because when I upgraded my computer and a media scan was conducted he found duplicates of all my media various times of at least 6-8. I've consolidated since my plates on 3-disc multi to, but have now records duplicated hundreds and thousands of duplicate media files. Previous versions of Media Player would allow me to select all files and then delete them both of the reader, but also from my hard drive. So now I'm stuck with more than 300 GB of duplicate media I have to search line by line through all my hard drives to find each duplicate both, unless I can get media player to do what it can. Any help in this area would be appreciated.

    Hello

    1. did you of recent changes on the computer?

    2. is Windows media player files in double creation during playback of music files?

    To delete duplicate entries, click on another feature tab in the drive (for example the current playback), and then click library.

    If this does not remove duplicates from your library, you can use the Add to library dialog box to search computer to analyze a file on your computer the duplicate entries not valid-pointing. The player will remove invalid entries in your library that point to files that no longer exist in the folder.

    Complete the steps above for files that are stored in the hard disks.

    Method 1: Use the add to Library dialog box search for computers

    (a) start Windows Media Player.

    (b) press F3 on your keyboard to open Add to the library of the find computers dialog box.

    (c) click the Browse button to locate the folder on your computer so that your library contains invalid entries. Specify the location of the folder in the box look in.

    If you are not sure what duplicate in your library entry is not valid, you can add a path column to display in your library. Specify the folder on your computer that corresponds to the path not valid file displayed in your library.

    (d) click on the Search button.

    The player will search for digital media files and playlists in the folder that you specify and remove invalid entries in your library that point to files that no longer exist in the folder. If not valid in double entries point to other folders on your computer, repeat this procedure, specify a different folder every time.

    If only a small number of duplicate entries exist, you can delete those invalid manually by right-clicking on the invalid entry, and then clicking Delete .

    For large double-number of entries in your library (or if all your library is duplicated), it might be better to create a new library and delete the files.

    Method 2:

    After you remove the duplicate entries, run the troubleshooting of Windows Media Library settings to solve this problem.

    Open the troubleshooter in Windows Media Library

    There are two approaches you can take.

    One solution: you can copy files into smaller "chunks" until you identify the file that causes the error, and then try to find out what is the problem with this file.

    Another solution is to download the program "Robust copy" (Robocopy) to Microsoft and it allows to copy your files.  You download and install in the Windows 2003 Resource Kit (works fine on XP).

    Windows Server 2003 Resource Kit:
    <>http://www.Microsoft.com/en-US/Download/details.aspx?ID=17657 >

    Once installed, you can open a command prompt window (start-> Run-> "cmd") and enter the command:
    Robocopy "C:\photos" 'E:\photos' /R:5 / s
    Where "C:\photos" will be replaced by the source directory, and the 'E:\photos' is the destination directory.  the "/ S" option will copy the subdirectories and the R:5 option retries 5 times on error before moving on to the next file.  Errors should be displayed on the screen and I found errors of command line to be more descriptive than GUI errors.  There are a lot more options, but this should help you get started.
