Parameterized UVM Environment Creation Issue.

Selvavinayak

Hi all, 

  when we are trying to create Parameterized UVM environment, we are not able to pass parameter from top to bottom of the component.Please help Us to solve this Issue, Our Dummy Environment should be like below,

class driver (parameter DATAWIDTH)

bit[DATAWIDTH-1:0]data;

endclass:driver

class agent(parameter DATAWIDTH)

driver#(DATAWIDTH) driver_m;

class agent

class env();

  agent#() agent_m[];

function new();

  

endfunction

function build_phase();

  agent_m=new[3];

  agent_m[0]=agent#(32)::type_id::create("agent", this)

  agent_m[1]=agent#(64)::type_id::create("agent", this)

  agent_m[2]=agent#(128)::type_id::create("agent", this)

endfunction

endclass:env

we need to create agent with different parameters. we tried but, parameter value is not passing correctly some time we are facing fatal error.

Is any one have experience with this environment. please share the Information

Thanks,

  • Hi,

    I was facing the same issue when i am creating multiple Parameterized agent.

    You just will have to do is :

    // UVM Automation macros
    `uvm_component_utils(agent#(DATA_WIDTH));

    Here you will have to declare parameterize uvm automation macros in all the class where you have used the parametrization in class.

    please let me know if there is a issue.

    Regards,
