altlvds megafunction in QuartusII v10.0

Hi everyone,

I'm having troubles with instantiating the altlvds (rx or tx) megafunction in QuartusII v10.0.

When I try to add it as a symbol in mijn schematics file I get the standard megawizard plugin manager asking me what format the output file should be. I choose VHDL and click next. Then I get a quick progress bar but and then.. nothing.. :confused:

Has anyone else experienced this problem? What to do?

Thanks in advace,

Void_

    Hmm, I found out I can add it without using the megawizard plugin manager. But this is kinda lame though. I would like to use the plugin manager.

    I am also having problems with the LVDS function in Quartus II 10.0.

    I am not using schematic entry so I am just calling up the MegaWizard Plugin Manager from the Tools menu in Quartus. ALTLVDS_TX seems to work. However, when I try to use ALTVLDS_RX, the dialog is broken. For example, the channels drop down box does not contain any choices and does not allow you to type in a number. There seems to be no way to finish the process.

    kevin, are you using CIVGX? the issue is on page 16 of the 10.0 Release Notes:

    http://www.altera.com/literature/rn/rn_qts.pdf

    seems the Release Notes are a must read for this version

    That item in the release notes does seem to describe the symptoms I am seeing. However, I am using Cyclone III and Cyclone IV E, not Cyclone IV GX. Also, the described work around does not work. After selecting Stratix II GX and then clicking next the wizard freezes and the only thing I can do is close it.

    My current work around is to just use the mega wizard from 9.1sp2 to create the LVDS functions. The results seems to compile fine in 10.0.

    Hi,

    I got an answer from Altera which works at least for me.

    To work around this issue make sure the regional settings on your machine is set to English (UK or USA). This will not affect keyboard mappings, but will affect the default number separators:

    1) Open the Regional and Language Options menu from the Windows Control Panel.

    2) In the “Standards and Formats” box, select “English (UK)” or “English (Untied States)” from the drop down list.

    3) You should see the “.”’s change to “,” in the Number section of the samples window.

    Kind regards

    My computer is already set to English USA, so that workaround is not going to work for me.

    Perhaps the results when setting the region to English USA differ between versions of Window. Perhaps one could manually edit the various settings in the region settings to make it work. Right now, I couldn't be bothered enough to try as I am just using the 9.1sp2 wizard whenever I need to change LVDS settings.

    I'm encountering similar problems with the ALTLVDS_TX MegaWizard, for an Stratix IV GX part. My ALTLVDS_RX seems to at least start, but the GUI doesn't match the description in the user guide, and most of the tick boxes I need are grayed out.

    Even the description of the ports and parameters in the user guide doesn't match those listed in the specification within the same document.

    And just now I'm encountering fitter errors

    I'm using 10.0 SP1, and I've tried the quoted workaround, but it doesn't seem to change anything. I've got a service request in...
