Can anyone please tell me where can I get an entire running and simulated UVM example code . I tried checking in the downloads section but the code examples files seems to be corrupted.

Hi Clair,

You can download UVM class library from the below website

http://www.accellera.org/downloads/standards/uvm

Below website is good for basic setup and understanding
http://www.testbench.in/UL_00_INDEX.html

Let me know in case you face any issue.

Thank you for the reference links. I have been using the above link and complted few modules. However, for the driver module, I get a syntax error for “configuration cfg” in the below code. Could you please guide me thorough if possible.

class Driver extends uvm_driver #(Packet);

Configuration cfg;

virtual input_interface.IP   input_intf;
virtual mem_interface.MEM  mem_intf;

uvm_analysis_port #(Packet) Drvr2Sb_port;

`uvm_component_utils(Driver)

function new( string name = "" , uvm_component parent = null) ;
    super.new( name , parent );
endfunction : new

virtual function void build();
    super.build();
    Drvr2Sb_port = new("Drvr2Sb", this);
endfunction :  build

virtual function void end_of_elaboration();
    uvm_object tmp;
    super.end_of_elaboration();
    assert(get_config_object("Configuration",tmp));
    $cast(cfg,tmp);
    this.input_intf = cfg.input_intf;
    this.mem_intf = cfg.mem_intf;
endfunction : end_of_elaboration

Hi Clair,

You can use the examples listed on the link below:

https://verificationacademy.com/cookbook/cookbook-code-examples

You should be able to use the Register examples.

Hi Clair, thank you for your message. The code examples on the Academy Cookbook site here should be useful for you.

You mentioned corrupted files - some of our users reported problems recently, downloading and unpacking the code example tarballs - the problem seems to be dependent on different software versions, and we are investigating a permanent fix.

In the meantime, if you try to unpack a downloaded file with ‘tar zxf uvm_tb_build_ss_tb.tgz’ and get an error “does not look like a tar archive”, please try again with a 2-step unpacking as follows:

% gunzip uvm_tb_build_ss_tb.tgz
% tar xf uvm_tb_build_ss_tb.tar

Hopefully that will get you started with the many UVM code examples that are available on the site here.

Thanks,
