Quartus 15 ALTLVDS_RX MegaWizard Errors

I'm trying to create IP ALTLVDS_RX for project with Cyclone V.

But with defaults parameters MegaWizard says 

Error: Parameter VALID_PHASE_INCLOCK has been assigned the value 0.00 which is incompatible with the current settings of DESERIALIZATION_FACTOR(4), INPUT_DATA_RATE(800), INTENDED_DEVICE_FAMILY(Cyclone V), LE_SERDES(UNDEFINED), LVDS_RX(UNDEFINED), PLL_FREQ(UNDEFINED), USING_FLEXIBLE_LVDS(UNDEFINED). The legal value is 0,00|22,50|45,00|67,50|90,00|112,50|135,00|157,50|180,00|202,50|225,00|247,50|270,00|292,50|315,00|337,50|
Error: Parameter VALID_PHASE_RXIN has been assigned the value 0.00 ...

It gives Error if I check "use external PLL"

"What is the phase alignment of 'rx_in' with respect to 'rx_inclock' " suggests 0.00 and nothing more.

I have not found parameters which changes Parameter VALID_PHASE_INCLOCK error .

How can I solve this problem? Did anybody used ALTLVDS_RX with Quartus 15 and Cyclone V ?

    Hi,

    I tried with Quartus II 15.0.2 on my side, with default settings + enabled "use external PLL", there is no similar error observed. Can you tried with the 15.0.2? Probably they have fixed it during the updates.

    I've download the last updates. Now I have Quartus II 64-bit Version 15.02 Build 153 07/15/215 SJ Web Edition for Linux.

    And it is what I see when I start MegaWizard for ALTLVDS_RX:

    Checking "Use external PLL" does not affects to the error.

    Empty field and selection list "Currently selected device family" confuses me. Is it OK? may be IP conflicts with device package?

    You would need to specify the device family as there might be different set of internal parameters for different device families. If you select Cyclone V + "use external PLL", is the error still exist?

    The "Currently selected device family" ComboBox is empty if "Match project/default" is unchecked.

    If I do check/uncheck "Use external PLL" checkbox, error list does not changes.

    This seems strange. Can you try by first creating a project and select a device, then only do the instantiation to see if issue still there?

    I have create new project, select 5CSEBA2U23C8, then start ALTLVDS_RX wizard and I got the same errors.

    The "Currently selected device family" ComboBox is empty.

    I've try Cyclone IV and Cyclone IV GX, and got the same result.

    Probably you should file a service request to Altera on this since you have done quite some debugging. If you have a Windows OS, test with Windows Quartus also.

    This looks like it might be a locale thing, note that the legal values all have ',' for decimal separator but your (illegal) entry is 0.00. Can you enter 0,00? Or just 0? Or change your locale settings so the default separator is '.'?

    Just a thought...

    Yes, problem with regional numbers interpretation.

    I can not replace 0,00 in GUI, it is in ComboBox with uneditable values.

    I've change locale and error disappeared.

    That sounds like a bug that needs to be reported! Not uncommon though, from my limited experience. "Brand-X" tools had the same issue.
