I just noticed, that the PLL Megawizard does not start up in Quartus 13.1 any more, neither when creating a new component, nor when editing an existing one. The blue "Loading Megawizard" window shortly appears on the screen, and then diappears. I can confirm that the PLL megawizard still worked in Quartus 13.0sp1. In the task manager I can see, that a java process appears in the list for a second or so, but then it disappears again. If I enable the task manager to show the command line of the process, the line appears incompletely to me: "c:/altera/13.1/quartus/bin/jre/bin/javaw.exe" -Xms64m -Xmx 1g -jar "c:/altera/13.1/quartus//sopc_builder/model/lib/com.altera.iplauncher.jar" "--wizard=altera_pll" "--early_gen=on" "--wizard_file=c:/altera/13.1/ip/altera/altera_pll//source/top/pll_hw.tcl" "-- Nevertheless, this is probably not the cause since I can see the same with Quartus 13.0sp1. Any ideas?

Hi, i recently updated to Quartus Version 13.1 and i experience the same. The Start Wizard window appears but then nothing happens. Did you solve this problem?

Hi, I asked the Altera Support for help but that was not very fruitful. I finally circumvented the problem by installing Quartus 13.1 on a different PC where the problem does not occur any more. The Altera support was not able to reproduce the problem. As soon as I reported that the software was running on a different PC, the supporter came to the conclusion that this is not a software bug. If you ask me, I do not agree with this conclusion. Any detail seems to be different in the overall windows environment that is not handled properly and that makes the software to fail. I'd suggest to try two things: Open a support ticket at Altera by yourself to show them, that there are other people who have the same problem. Further try to install Quartus on a different machine and check if the issue occurs there (if you have the opportunity to do so). Finally, you could still consider to reinstall windows and Quartus 13.1 to get a clean installation (or use a virtual machine to reduce effort).

Hi, i installed Quartus several times but the error still occurs and still i am not able to instantiate a pll in either quartus nor qsys. I dont have the possibility to reinstall windows since the pc came from our it department. On my laptop everything works fine, but it has not the capacities to compile or simulate in a short time. So i will also open a ticket and hopefully this bug will be fixed or at least recognized ;) Here is the error message i get in qsys: Error: while executing "__altera__safe_load C:/altera/13.1/quartus/bin/qcl_pll_tcl.dll generic_pll" ("uplevel" body line 1) invoked from within "uplevel 1 " (procedure "load" line 2) invoked from within "load generic_pll" ("windows" arm line 2) invoked from within "switch $tcl_platform(platform) { windows { load generic_pll } unix { load [file join $::qu..." ("package ifneeded ::altera::generic_pll 1.0" script) invoked from within "package require ::altera::generic_pll" Error: An instance of Altera PLL could not be created. The component had an unexpected internal error.

Hi, keep us informed about your progress. Good luck!

Hey, so the support request is submitted. Since i really need a PLL in my design can i use one for a different device family, or is that bad practice? I use a cyclone V device but i am able to use a pll for a cyclone iv.

this may be related if you have different versions of quartus installed simultaneously.i uninstalled everything and reinstalled quartus 13.1 sp2 . this fixed the problem. why reinstalling didn't helped you, -have no idea.

Did the reinstall help you? For me it did not work.

Well, yes and the hint from ilik seems to be an idea, too. It took me, or to be honest, i took my PC about 4 hours to uninstall two version of 13.1, one 10.1 and one other version of 13.1 for the SoC(?), which were installed in parallel.
Only at the very end, quartus 13.1 allowed me to install a blank version in the default directory and after that, everything went well. I didn´t change/install any other software like the c runtimes :/

I have the same problem with Quartus 13.1. In Quartus 14.0 Altera PLL crashes the Qsys without any prompts.
Does anybody found a solution?

are you sure you have uninstalled including your current quartus? do not leave any of them. uninstall all. then reinstall one quartus. if it doesnt help... i don't know what to do. i would reinstall OS and make a good backup image of entire system so that if such happens again, you could regenerate everything in 30minutes.
