DE1 Cyclone V Verilog

[Yassine-Ca]

Hello, 

I create a small project using Quartus and Platform Designer.

In Platform Designer, I create NIOS II, On-Chip memory, JTAG UART and FIFO Avalon memory, I intrconnect them then I have generated Verilog , please see image below.

When I try to compile over Quartus, I get this error : Error (12002): Port "avalonmm_read_slave_read" does not exist in macrofunction "nios2_memory" , I know that it means that there is no signal in this name.

My question is, where are located the generated port signals ( Read from memory, write to memory) from generated by Platfom Designer, I found just clock signal and reset signal.

Please find attached the generated files by Platform Designer.

Thank you

The _inst.v file is just an instantiation template for instantiated the PD system in an upper-level design file in Quartus.  It only lists the exported interfaces, which in your case are just clock and reset.

If you are using this system as your top-level design in your Quartus project, set the top-level entity name in Quartus to NIOS2_memory_JTAG and add the .qsys file to your project.  Regenerate the system in PD and then recompile in Quartus.

Hi,

              Thank you for your reply.

              I use another file as my top-level, and i declare the NIOS2_memory_JTAG inside it.

              Because I have the addresses of FIFO in, out and csr, on chip , nios2 debug memory slave, Can I just use these with bus address to write data to the FIFO memory.

              Regards.

You mean in your code for the processor?  Sure.  But you can find all the macros in the generated system.h file from PD.

Side note: I don't know what version of Quartus you are using, but it's not recommended to start new designs with Nios II since it's been obsoleted by Nios V.

Hi,

                My FPGA is DE1 and the quartus prime version 23.1 std.

                 My top-level file is used to display retreived data from FIFO memory into 7-segments.

                  I serached for the system.h file but not found in project folders, where can I find it, as i mentioned the NIOS2 files was generated by Platform Designer Qsys.

                  Is the DE1 supports Nios V, if Yes I can start a new design.

                  Regards.

[sstrell]

Sorry, I forgot you have to generate the BSP (board support package) first to create the system.h file.

Nios V is supported in all devices that supported Nios II (as long as you have device resources available to implement it of course).

Hi,

            In the BSP file just for Clk and reset.

            I'm searching now macros for intel in this link, is This can help?

Huh?  No, that document has nothing to do with this.  See this training: https://learning.intel.com/Developer/learn/courses/14714/niosr-v-software-development-flow-with-ashling-riscfree-ide-for-intelr-fpga

Hi,

              Sorry It was a mistake sending that reply in this page.

              From Quartus I try to open NIOS 2 software build tool to generate BSP but no way.

              What do you suggest, is the quartus version standard is not working for this?.

              Best regards.

[sstrell]

For Nios II in older versions of Quartus, you have to use the bsp-editor from the Nios command shell to configure and generate the BSP.

Hi,

              Have you the link to download the version?.

               Regards.

[Yassine-Ca]

Hi,

                  I installed eclipse, now it's OK.

                  I will procced to BSP files.

                  Regards.

I believe sstrell has answered your inquiry.

Do you need further help regarding this case?

Hi Richard,

                      Thank you for your support.

                        I'm using Quartus 23.1, I have issue with Eclipse for NIOS II with elf file not existing.

                         I browse the Nios II Handbook, I found that the latest version of Quartus is 21.3

                         Can I get a problem of incompatibility.

                          Regards.

[Yassine-Ca]

Hi,

              In the NIOS II new book, there is compatibility.

              The problem was in the template in Eclipse, when I changed it to Helloworld small, the ELF file is generated.

                I got these warnings on the Quartus:

Warning (10036): Verilog HDL or VHDL warning at seven_segment_display.v(18): object "display_data" assigned a value but never read
Info (12128): Elaborating entity "seven_segment_decoder" for hierarchy "seven_segment_decoder:temp_tens_decoder"
Warning (10036):............................

                 To share the solution with you: I just added the module that declare the system components (NIOS 2+On Chip Memory + FIFO + JTAG)  in the top level module declaration with the qip file added to the project.

Here the declaration inside top level,according to my project :

temp_hum u_rdwr (
.clk_clk(clk),
);

                                Regards.

I believe your follow-up question is related to Nios II, which unfortunately is not within my area of expertise.

Could you please raise a separate case for your follow-up technical problem, and an agent will be assigned to your case?

At Altera, we prefer a new case for each unique technical problem, as it aids our case analysis and helps us assess our customer support requirements.

Thank you for your understanding.
