get_response() with UVM RAL

Recommended Posts


I am currently working with UVM RAL and I encountered this error:

"Response queue overflow, response is dropped"

Got the above error since my driver was calling seq_item_port.item_done(rsp). The error however goes when I change it to seq_item_port.item_done() in the driver.

My UVM RAL sequence doesn't explicitly make a call to get_response(rsp) but the register reads and writes work perfectly. My question is,how does RAL sequence get the response back if we don't call the get_response() explicitly?
