  1. As an update to this issue...

    I have discovered that the Microblaze Quick start guide is lacking in some critical information with regards to creating a complete Microblaze example.  I realized that when I tried to open the block diagram and it was empty that I keyed into the problem...There is no design to implement!!!

    The next steps should be to add IP to a block diagram and then validate this diagram before attempting to synthesize...implement...ect

    I have not successfully implemented a complete Microblaze example yet but just wanted to let others know...

  2. Hello

    New to this forum and Microblaze.  I am trying to implement the bare-metal microblaze example as outlined in the "Microblaze quickstart guide".  I am using the Arty S7-25 development board with Vivado 2021.1.  I downloaded the support files from Digilent and am able to create the microcontroller project for this board.  When I try to run Implementation phase, I get the following error...

    [DRC INBB-3] Black Box Instances: Cell 'system_i' of type 'system' has undefined contents and is considered a black box.  The contents of this cell must be defined for opt_design to complete successfully.
     

    See vhdl code below from "system_wrapper" (file created for the example) - red text is the line the implementation fails on.

    library IEEE;
    use IEEE.STD_LOGIC_1164.ALL;
    library UNISIM;
    use UNISIM.VCOMPONENTS.ALL;
    entity system_wrapper is
    end system_wrapper;

    architecture STRUCTURE of system_wrapper is
      component system is
      end component system;
    begin
    system_i: component system
     ;
    end STRUCTURE;

     

    Any ideas what is going on?

    Thanks - project attached...
