Hi,
I am sending 5 transactions from producer, in consumer i am getting only last transaction from consumer repetitively. Can some help what can i do to get all transaction in consumer?
This is code below i tried:
`include “uvm_macros.svh”
import uvm_pkg::*;
class my_txn extends uvm_object;
rand int addr;
rand int txn_id;
uvm_object_utils_begin(my_txn) uvm_field_int(addr, UVM_DEFAULT)
uvm_field_int(txn_id, UVM_DEFAULT) uvm_object_utils_end
function new(string name=“my_txn”);
super.new(name);
endfunction
endclass: my_txn
class my_producer extends uvm_component;
`uvm_component_utils(my_producer)
uvm_analysis_port #(my_txn) analysis_port;
function new(string name, uvm_component parent);
super.new(name, parent);
endfunction
virtual function void build_phase(uvm_phase phase);
super.build_phase(phase);
analysis_port = new(“analysis_port”, this);
endfunction : build_phase
virtual task run_phase(uvm_phase phase);
my_txn txn;
int tx_cnt;
phase.raise_objection(this);
txn = my_txn::type_id::create(“txn”, this);
repeat(5) begin
void’(txn.randomize());
`uvm_info(get_type_name(), $sformatf(“txn #%0d\n%s”, tx_cnt, txn.sprint()), UVM_LOW);
analysis_port.write(txn);
tx_cnt += 1;
end
phase.drop_objection(this);
endtask:run_phase
endclass
class my_consumer extends uvm_component;
`uvm_component_utils(my_consumer)
uvm_analysis_port #(my_txn) analysis_export;
local uvm_tlm_analysis_fifo #(my_txn) analysis_fifo;
function new(string name, uvm_component parent);
super.new(name, parent);
endfunction
virtual function void build_phase(uvm_phase phase);
super.build_phase(phase);
analysis_export = new(“analysis_export”, this);
analysis_fifo = new(“analysis_fifo”, this);
endfunction : build_phase
virtual function void connect_phase(uvm_phase phase);
analysis_export.connect(analysis_fifo.analysis_export);
endfunction
virtual task run_phase(uvm_phase phase);
int tx_cnt;
phase.raise_objection(this);
#100ns;
//forever begin
repeat(6) begin
my_txn txn;
analysis_fifo.get(txn);
`uvm_info(get_type_name(), $sformatf(“txn #%0d\n%s”, tx_cnt, txn.sprint()), UVM_LOW);
tx_cnt += 1;
end
phase.drop_objection(this);
endtask:run_phase
endclass: my_consumer
class my_env extends uvm_env;
`uvm_component_utils(my_env)
my_producer m_producer;
my_consumer m_consumer;
function new(string name, uvm_component parent);
super.new(name, parent);
endfunction
virtual function void build_phase(uvm_phase phase);
super.build_phase(phase);
m_producer = my_producer::type_id::create(“m_producer”, this);
m_consumer = my_consumer::type_id::create(“m_consumer”, this);
endfunction : build_phase
virtual function void connect_phase(uvm_phase phase);
m_producer.analysis_port.connect(m_consumer.analysis_export);
endfunction : connect_phase
endclass : my_env
class my_test extends uvm_test;
`uvm_component_utils(my_test)
my_env m_env;
function new(string name, uvm_component parent);
super.new(name, parent);
endfunction
virtual function void build_phase(uvm_phase phase);
super.build_phase(phase);
m_env = my_env::type_id::create(“m_env”, this);
endfunction : build_phase
task run_phase(uvm_phase phase);
phase.raise_objection(this);
#100;
phase.drop_objection(this);
endtask
endclass
module tb_top;
initial begin
run_test(“my_test”);
end
endmodule
