Enabling UVM debug in simvision

Hi ,

I came to know that there is a way to enable some uvm debug options in simvision. 

Can someone let me know what are the switches that needs to be enabled for this.

Thanks,

DN

    Are you referring to the TCL commands to probe the UVM hierarchy?

    #Probe waveforms
    database -open -shm -into waves.shm waves -default # -event
    probe -create -database waves top -all -depth all # -memories
    probe -create -database waves $uvm:{uvm_test_top} -all -depth all -dynamic

    #stop at the end of the build phase and enable full verbosity
    #messaging and transaction recording
    uvm_phase -stop_at -build_done
    run
    uvm_message UVM_FULL *

    #Enable transaction recording
    uvm_set "*" "recording_detail" UVM_FULL
    if {!$simvision_attached} {
    run;
    exit;
    };

    Well not really a tcl script. I thought there was a possibility to enable some menu items in simivision to debug uvm enviroment. Will this tcl script actually display somethings in the waveform window? If yes then it may be good enough.
    How should this tcl script be invoked? Is it a input file for irun?

    Thanks,

    Can these things be done in simvision after the simulation is completed
    1>Capture classes in the wave database and show them in the waveform window
    2>Objects and their members in the wave database
    3>Follow class handle “pointers” to other objects
    4>Sequence items that hits the driver

    Basically debug complete class based transaction system in a gui

    Thanks

    You can explore the SimVision Debug Video Series. There is a video on using the SimVision UVM Toolbar.

    Other useful links:

    Documentation on the UVM Sequence Viewer

    These are available on the support.cadence.com site
