New ContributorI'm on Quartus Prime Lite 23.1 on Linux, and this ALTPLL Altera FPGA IP module (now called ALTPLL Intel FPGA IP) still does not work. Using the hack mentioned here I can get get the wizard to create it, but I cannot configure it. Any time you get to the (3) Output Clocks page, the wizard crashes. The hack seems to keep it from aborting and deleting it, but there's no way to configure the clocks.
This is a major bummer... it seems to be unusable. If anyone knows how to get around this so the output clocks can be configured... I'd greatly appreciate it.
New Contributor@Serqetry, last year when I posted the above, I was working on the University of Colorado Boulder's FPGA specialization on Coursera. A couple things I learned. Ultimately, Altera (now Intel) do not do a good job of supporting Linux. They just don't. Other tools within the Intel tool chain became maddeningly difficult to get work (if ever) under Linux. Don't even getting me started on Nios. In the end, I spent days of time trying to get Linux to work. Honestly, I switched to Windows. And, Windows just worked. If you have the option to switch to a Windows PC with Intel tools, I would. If you don't, you're going to face an uphill battle as this is will likely be the first of many challenges. I know this doesn't answer your question. But, I wouldn't wish my journey last year (before I switched to Windows) on my worst enemy. Sorry.
New ContributorThanks for the reply! I'm taking the same Coursera courses now, so that's one reason I ran into the exact same problem as you. I know what you mean, Linux usually gets way less attention than Windows, but honestly I'm super grateful Quartus Prime and the other tools are supported on Linux because I'd rather quit computers and electronics and take up botany than daily drive Windows. I do keep a Windows VM around for the situations where something just won't work otherwise... but honestly my biggest complaint with the Coursera stuff is that classes are so horribly out of date. Quartus Prime 16?... why do they not update these courses? I'm amazed I've been able to get this far with the newer versions of Quartus, There's definitely been some ancient crusty file compatibility issues but that's Coursera's fault. You may be right and I'll run into even more trouble in the later courses, so I'll keep that VM on standby and try to not struggle too much. Thanks for the heads up.
New ContributorI'm actually on Quartus Prime Like 23.1 for Windows and the same exact thing happens here (so it's not just a Linux issue).
I applied the modification above (the file was located in C:\intelFPGA_lite\23.1std\ip\altera\sopc_builder_ip\altera_avalon_mega_common )
but it did not help
You can get to the PLL Reconfiguration but when you click Next, the wizard closes and the PLL you were building disappears from the design.
New ContributorI'm on Quartus Prime Lite 23.1 on Linux too, on the same Coursera class. I managed to configure the clocks by attaching gdb to the wizard, setting a breakpoint on the crashing function, and forcing return of two frames always when it gets called.
First, to enable attaching gdb to a running proces, run as root:
# echo 0 > /proc/sys/kernel/yama/ptrace_scope
Run the PLL wizard from Quartus. In a separate terminal, find the PID of the wizard process (the number from the second column):
$ ps aux | grep mega_altpllq
Attach gdb to it (substitute the proper pid), set up a few things, and resume the wizard:
$ gdb -p 260525
(gdb) set confirm off
(gdb) br _ZN27ALTCLKLOCK_CLK_SETTING_PAGE29should_enable_disable_controlERK10UI_QSTRING
(gdb) c
Proceed with the wizard. When switching to the (3) Output Clocks page, or on any modification of the data therein (which you need a handful of times), the breakpoint triggers. Switch to the terminal with gdb and do
(gdb) return
(gdb) return
(gdb) c
When you're done with the wizard, you can exit the gdb and close the terminal.
I also applied the change to the if in the .tcl file. I don't know if it's needed.
I agree with the sentiment that this is a fun class and that the tooling is a huge pain.
