Complier Error, Quartus Prime Fitter was unsuccessful

Hi,

I tried to compile a compution.cl file with aoc command to generate computation.aocx.

(The command line is aoc -v computation.cl -o computation.aocx)

But It failed to generate .aocx file and only .aoco file was generated.

With the -v , it showed the stage of compiling on the screen and the information is :

------screen-------

aoc: environment checks are completed successfully.

you are now compiling the full flow!!

aoc: selected default target board a10gx

aoc: running opencl parser....

aoc: opencl parser completed successfully.

aoc: compiling....

aoc: linking with ip library ...

warning: kernel 'fullylayer' has unused argument 'inputdatasize'

aoc: first stage compilation completed successfully.

error: compiler error, not able to generate hardware

---------------------

Then I checked computation.log in the computation floder. It showed no error occured :

-------computation.log---------

----------------------------------

Then I checked top.fit.rpt for more information and the usage of resource in this file showed the resource was enough:

What's more, my OS is Windows 10 Professional , Quartus version is 16.1.1, AOC version is 16.1.0, and It generated .aocx file successfully Before with other OpenCL kernel file.

Why it failed to generate .aocx file? And what should I do to shoot this trouble?

I am waiting for your reply. Thank you.

    Multiple things to note:

    1. The "Warning: Kernel 'fullyLayer' has unused argument 'inputDataSize'" is not normal; make sure you haven't made any mistakes in the design of your kernel that something is being optimized out by the compiler. If the argument is really not used, just remove it.

    2. "Total block memory bits ; 22,860,776 / 43,642,880 ( 52 % )" and "Total RAM Blocks ; 218 / 2,131 ( 10 % ) ;" does not make any sense; you are probably overutilizing the Block RAMs and the Block RAM number is "overflowing" in the report. I have seen this multiple times before. Actual utilization is probably 110% and not 10%.

    3. Compilation is failing during placement, most likely due to Block RAMs overutilization. Please attach the "quartus_sh_compile.log" file so that I can take a closer look.

    4. Never mix different versions of AOC and Quartus; always use a version x.y.z with biggest y and z for both. In your case, make sure to update both Quartus and AOC to 16.1.2.

    Thanks for ur help!

    I followed ur advise and removed the argument which is useless in the kernel code, Now, I'm trying to update Quartus and AOC to 16.1.2.

    Attachment is the file "quartus_sh_compile.log", at the end of log it shows some errors that " Error (18999): Placement cannot find a legal solution. ". What does it mean?

    It seems the log file is too big to update, so I packaging it. Im sorry about additional work you have to do with the .zip file. If it is not convenient, I ll attach the file with bottom lines in the log file.

    Again, Thanks for your help!

    "Placement cannot find a legal solution" usually means that you need some resource (RAM, DSP, etc.) on the FPGA, but that resource has been fully used and there is nothing else left.

    The closest thing I could find to a meaningful error message in the log was this: 

    Error (17937): The inputs to the LAB at location (68,69) exceed the number of legal inputs. This LAB may be locked or have other LAB-level input restrictions. Refer to the submessage(s) for the specific input nodes that do not fit in the LAB. Remove some inputs to this LAB so the number of inputs does not exceed the legal limit. File: c:/intelfpga_pro/16.1/quartus/libraries/megafunctions/altera_counter.sv Line: 59

    But I had personally never seen such message before; the message that is printed in the log when you overutilize the Block RAMs is different. Can you please retry the compilation after updating to 16.1.2 and see what happens?

    Also please add --report to your compilation log and post the area estimation that you receive in stdout after adding that switch.

    --------------------Update--------------------

    My DSP package do not support 16.1.2 and higher version, this is the reason that the strange errors occured.

    Now I rollback both Quartus and AOC to 16.1.1, the problem has been solved.

    i ll update the result of this compilation later. Thanks for ur help!.

    following questions have been solved.

    ============

    Hi,

    I updated quartus and aoc/aocl to 16.1.2, but there were some strange errors......

    I try to compile a simple OpenCL kernel code with aoc -v --report xxx.cl -o xxx.aocx

    But the compilation was failed and the quartus_sh_compile showed:

    But I have already used customized bsp package. What's more, aocl diagnose also failed and the screen showed:

    DSP or BSP? It seems you are using Altera's Arria 10 devkit; the BSP for that board is updated with every version of Quartus and is included in the package itself. There should be no need to use an older version of Quartus/AOC.

    I am using Speed-clouds hardware acceleration platform with arria10. According to the manual, I have to replace a10gx\hardware folder with another folder that Speed-Clouds provided, or the .aocx do not fit my board.

    But the errors occured again:

    1. Sometimes the diagnosis passed, and sometimes failed with the mismatch of writing and readback.

    2. I try to ignore diagnosis and program with host code, There is still a mmd error: can't load the windriver library. and the procedure still executed with the error. Sometimes it fails to create program with binary, it shows "error: cl_invalid_binary". But sometimes the board works well with the mmd error.

    The result of diagnosis and jobs is random, reboot seems do not solve any problems.

    I am wondering if there are some hardware fault occured?

    Thanks for ur help !

    Only the hardware folder? That sound strange. I think they should also correct timing settings in the PCI-E driver and provide their own driver.

    What you describe can have two explanations:

    - There is something wrong with the BSP or the PCI-E driver.

    - The FPGA board's memory is problematic.

    Based on what you describe, I see the former as the more likely reason.

    I try to find where the windriver library is but failed. Do u have any idea about this issue?

    Many thanks.

    "windriver" sounds like the OS is windows. I have never used Windows for this particular work. If the OS is NOT Windows, then there must be something seriously wrong with the BSP they have provided you with.

    I've solved this problem with the Intel FPGA SDK for OpenCL Custom Platform Toolkit User Guide, section 1.4.4. I checked register key named HKEY_LOCAL_MACHINE\SOFTWARE\Altera\OpenCL\Board and deleted the redundant item that added by another version of Quartus. The MMD ERROR disappeared.
