ERROR building simple NIOSV Compact project - ERROR building simple NIOSV Compact project Hello and greetings All Quartus + NIOSV experts, or indeed anybody who can help me fix this error ! I am trying to build a System Verilog design, based on Platform Designer, which uses a NIOSV compact IP core. I am using Quartus Prime Version 25,1 Standard Edition on a Windows 10 Machine. When trying to compile my test design i get these 2 errors : Error (10170): Verilog HDL syntax error at niosv_cpp_fsm.sv(1418) near text: "'"; expecting ":", or "?", or binary operator. Check for and fix any syntax errors that appear immediately before or at the specified keyword. The Intel FPGA Knowledge Database contains many articles with specific details on how to resolve this error. Visit the Knowledge Database at https://www.altera.com/support/support-resources/knowledge-base/search.html and search for this specific error message number. Error (10112): Ignored design unit "niosv_cpp_fsm" at niosv_cpp_fsm.sv(18) due to previous errors Error 10112 is caused by previous error 10170. Does anybody have an idea why i get these errors ? I can't see the offending SV code because its encrypted (of course!). Is there a fix as well for this problem ?

Archer_Altera Replies: Re: ERROR building simple NIOSV Compact project Hi Barry There is a document fo the Nios V boot methods and steps on creating the project in the link below: https://www.intel.com/content/www/us/en/docs/programmable/726952/25-1/processor-hardware-system-design-with.html Regards tehjingy Replies: Re: ERROR building simple NIOSV Compact project Hi Frank, Thanks and now i can see my NIOSV compact core appears to be building ! Many thanks for your help. Can i ask if you know: a) If there is a Tutorial guide /example design(s) from ALTERA for designing with and implementing the NIOSV core in an ALTERA FPGA ? I am using a MAX10 devices now but i will be using this processor with other ALTERA FPGAs in the near future. b) Where is the location for the best documentation to which i can refer for using NIOSV cores in ALTERA FPGAs so that i can Bookmark the place ? Thanks, Barry Replies: Re: ERROR building simple NIOSV Compact project Hi Barry, Only qip file is needed. Regards, Archer_Altera Replies: Re: ERROR building simple NIOSV Compact project Hi Archer, Thanks for the tips ! I did see that step but i my may have forgotten to do that initially. Now i have done that and when i look into the FILES included in my project (which is called readout_fpga) i can see that i have added both a readout_fpga.qsys file and a readout_fpga.qip file from the synthesis directory. Is that correct ? Or should i delete the qsys file as it may cause confusion and just leave the qip file in my project ? Thanks, Barry Replies: Re: ERROR building simple NIOSV Compact project Hi Barry, Rather than Adding QSYS into project, please add QIP into the project. From 25.1std, the tool supports QIP only due to a change in Quartus compiler. The tool also prompts with message below. You may find a qip file located in the same folder of qsys system top level hdl file under project directory liking this. Hope this is helpful. Archer_Altera Replies: Re: ERROR building simple NIOSV Compact project Hi Archer_Altera, Thanks for your quick reply and analysis. Do you think it could be a tool installation problem ? Or a tool version issue ? Maybe other Standard editions don't have this problem ? I don't know yet because i have only managed to install the latest version of Standard edition. Thanks, Barry Replies: Re: ERROR building simple NIOSV Compact project Hi Barry, I can reproduce the issue you met on my side. This needs time for us to find the root cause. I will let you know when there is progress about this. Regards, Archer_Altera
