Quartus_Lite_22_1_not_generating_time_limit_sof

[FPGA70]

I'm resurrecting a Cyclone IV project from a few years back.  The last time I compiled and ran it was with version 20.1.  Within the last week I updated to version 22.1.  I am and have been running the Linux versions of Quartus Lite.

I recreated the project in the latest version in case there were incompatibilities between versions.  I would like to generate the BSP so that I can download some C-code in Eclipse in order to communicate with my PC, but I am running into a problem.

For IP I am using a Nios II/e and a PLL.  Everything compiles fine and a standard .sof is generated, but the time_limit.sof is not generated.

When I look at the 'IP Cores Summary' in 'Analysis & Synthesis' I see 6 instances of Signal Tap which I assume, because it indicates it is licensed, is the cause of Quartus Lite not generating the time_limit.sof.

I have verified that Settings/Signal Tap Logic Analyzer/ DOES NOT have 'Enable Signal Tap Logic Analyzer' checked. Any ideas would be appreciated.

Thanks

If the IP has been licensed (not on evaluation license), then the Quartus will generated .sof file.

Why use Time-Limited Programming File when you have the standard .sof file that works without a time limitation?

You can check your IP license status at the assembly report and compare the differences between two projects.

It should show you a list of all the cores that you used that require a license. It should tell you exactly which core you used that made your sof file time limited.

Signal Tap is not a licensed IP so that wouldn't prevent you from getting a .sof file, time-limited or otherwise.  But it doesn't make sense that Signal Tap is disabled and yet you are seeing it.  Are you confusing Signal Tap with something like "sld_hub"?  That's just the JTAG interface for debugging.

I use Pro so the setting may be in a different location, but check that you have .sof file generation (the Assembler) enabled or try running the Assembler manually from the Processing menu to see if it spits out a file.  Also check Assignments -> Device -> Device and Pin Options and Assignments -> Settings -> Assembler.

It has been a few years since I ran licensed copies of Vivado or Quartus at work.  These days I run the Lite version of Quartus which works great for my hobby stuff. 

You are right that there was a difference between the project I ran some years back and the one I am trying to get to run under 22.1.  I used Nios II/f then, but I found literature that indicated it was not available for this latest version of Quartus Lite so I am running Nios II/e which works fine for my purposes.  In the past I would see a time-limit.sof generated, but maybe Nios II/e does not do that.  Selecting the Nios II/e compiles with no errors.

The problem I am running into now is that when I try to generate a "Neos II Application and BSP from Template" with Eclipse, it generates 3 errors during Build even when using the standard "hello world small" file.  Guess it is time to go over to the Eclipse forum and bug them.

Thanks for your help

I believe that Nios II/e is free to use so that could be why there is no time-limited .sof generated this time.

Please do bug the Nios expert for your follow-up question.  ;  ) 

Anyhow, I’m glad that your question has been addressed, I now transition this thread to community support.

Thank you.

I guess there's a misunderstanding here.  Are you saying you get *no* .sof file or that you do get a .sof file but you expect it to be time-limited?

If you get no .sof file at all, then follow what I said above.  If you are saying you get a .sof but it is not time-limited, that's because II/e does not require a license (as was mentioned) while II/f (which does still exist) does require a license.  It sounds like this is what you mean.

Thank you for your response.  After I build the project I get a .sof file, but I expected the time-limited version. 

Speculation:  I had used the Nios II/f in with an earlier version of Quartus Lite (this might have been before Altera was bought by Intel) so I am assuming that Quartus Lite used to generate a time-limited.sof (good for 1 hour). 

Now it is not possible to use the II/f with Lite and generate the time-limited.sof.  This is okay because I am not using the resources supplied beyond the II/e core.  As I mentioned, this is just a hobby now that I am retired and playing mostly with ham radio and trivial projects compared to years back. 

You can close this item, but I do have a question for you.  I downloaded Eclipse Mars.2 Release (4.5.2) but it fails when I try to create the Nios II BSP.  I tried a generic 'Hello World' code with the Nios II BSP, but I still get the same failure report (see attachment).  Is this something for the Intel forum or should I chat with the Eclipse organization?  Searching both sites, I did not find what I thought was a similar problem. 

Last note:  Just before upgrading the Quartus and Eclipse applications, I upgraded to Linux MInt 21.1.

Thanks again.  I appreciate the cycles you have spent on this ticket.
