  1. I am learning UVM. So far I was able to create the following environment for my DUT. Agents with monitors, drivers and sequences for all of the input-output interfaces from my DUT. A top level UVM env. Sequences to send valid data to DUT. I yet to implement scoreboard. I'm having some trouble to understand how to handle scenarios like following: For one of my tb->dut interfaces, TB needs to wait for an event (or transaction) from DUT. Once it receives the transaction from DUT, TB needs to send back a response. What is the best way to implement this? How can I monitor DUT transaction from sequence? I assume I need to wait for an event or something similar which will tell me that DUT has a new valid output in its interface. My agents have monitors which will monitor any new output signals from DUT. So, do I need to somehow bring this data from agent's monitor to my test/sequence class? I know that monitor has an analysis port and it can be used to send received data to scoreboard for checking. So, do I need to use the same port to read DUT output data, create valid response and send it to DUT? Thanks!
  2. Hello, I'm getting the following compilation error and not quite sure the reason behind this. I would really appreciate any input on this. "PATH_TO_MY_TOOL_DIR/uvm_lib/uvm_ml/sc/ml_uvm/ml_uvm_unilang.h", line 52: error: invalid redeclaration of type name "scSessionArgumentsT" (declared at line 2347 of "$CDSROOT/tools/systemc/include_ pch/64bit/sysc/cosim/scCommon.h") typedef struct scSessionArguments scSessionArgumentsT; I'm not sure if there is anything wrong with my tool setup or compilation script. What might be the reason behind this error?
