Hi Team,

 

I downloaded the uvm_ref_flow_1.2.tar.gz

 

In this example I am seeing for uart_ctrl_env.sv . Why the below lines are removed ?

 

// uart_ctrl_reg_sequencer reg_sequencer;  //KAM - removed register sequencer

//reg_sequencer = uart_ctrl_reg_sequencer::type_id::create("reg_sequencer", this);  //KAM - removed register sequencer

 

But looks like as per the Cook book we should have this code here . Is this a old code which is not working ?

 

The other question I have , In the flow example why we are not using the UVM reg layer for creating the interrupt sequence, We are directly creating apb seq .

I think it should have been uvm_reg_sequence rather than APB sequence ?

 

Regards,

Deepak

Thanks for the upload. I converted this to Mentor UVM but have a problem with apb_slave_config. Wondering if anyone else has seen this error.

Test is u2a_a2u_rand_test .

Thanks,

Mike

This makes me wonder if this book is for the old release -  UVM 1.1?   A new version of UVM1.2 was released in 2014.
