Qsys 20.1 does not see RECORD type as port

Hi everyone,

I have my top entity design using input and output ports with record type put in a package.

The synthesis and simiulations are totally fine but, when i try to import my design in the Platform Designer to connect it with a Nios2, the "new component" wizard does not display the port put in the records.

All the other ports are fine and the file also update correctly if modified, all the ports that are put in a record are ignored and I can't proceed.

Is this a known issue? Is there a workaround?  Im using Quartus 20.1 Lite Free edition.

Waiting for your answer,

Davide

Can you post your code and what you're seeing?  It's not clear from your description what's going on.

Hi,


Can you provide the following so I can better understand your problem:

  1. Snapshots of your error
  2. (Assuming you're using VHDL) Which version of record data port are you using?
  3. What steps did you take to import your design to Platform Designer?


Thanks!

Hi,

I'm attaching the screenshots. The first one shows how the synthetizer understands correctly the group of signals as input port even if the signals are in a record.

The second photo shows the Platform Designer Wizard in wich I imported the exactly same files, but he doen't see any input port because of the record. If i put the signals inside the top entity without putting them in a record the platform designer works fine.

the top entity with record as ports:

entity IM_AXI4L_S is
    generic (
        G_NREG : positive := 16
    );
    port (
        SAXI4LINT_i_ACLK    : in  std_logic;
        SAXI4LINT_i_ARESETN : in  std_logic;
        SAXI4LINT_i_AXI4LM  : in  TR_AXI4L_M;
        SAXI4LINT_o_AXI4LS  : out TR_AXI4L_S;
        SAXI4LINT_o_CONTROL : out TA_AXIREG(G_NREG-1 downto 0)
    );
end IM_AXI4L_S;

the record definition:

type TR_AXI4L_M is record -- AXI4-Lite signals driven by master interface
        ARADDR  : std_logic_vector(ciAxiLiteAddrWidth-1 downto 0);
        AWADDR  : std_logic_vector(ciAxiLiteAddrWidth-1 downto 0);
        WDATA   : std_logic_vector(ciAxiLiteDataWidth-1 downto 0);
        WSTRB   : std_logic_vector(ciAxiLiteStrbWidth-1 downto 0);
        ARVALID : std_logic;
        AWVALID : std_logic;
        WVALID  : std_logic;
        RREADY  : std_logic;
        BREADY  : std_logic;
    end record;

Hi,


Record type uses VHDL-2008, which unfortunately isn't supported by Quartus Prime Lite Edition. It is however supported by the Pro and Standard Edition, you can see a comparison of the three versions here: https://www.intel.com/content/dam/www/programmable/us/en/pdfs/literature/po/ss-quartus-comparison.pd...
