Viewing dynamic objects in the Simvision waveform window

Hi All,

I'm having trouble displaying the value of class data members in a Simvision waveform window (currently using version 12.10-s006).

I'm using irun interactively to run my simulations, so I invoke irun with the following options:

irun -gui -access +rwc -linedebug ...etc

My testbench is UVM based so I use the UVM factory to build a simple test object.

At time 0 ns, I can see my classes in the SystemVerilog Class Browser, but there are no objects displayed (as the factory hasn't built them yet). I then run my simulation for 1 ns and I can then see an object displayed for the class containing the data member I'm interested in. Having clicked on the object (5854_1), it is then displayed in the design browser as @5854_1. I can expand the object to show the data member and I can right click the mouse to select the 'Create Probe ...' menu option.

Having created a probe, the data member is displayed in my waveform window, but when I then run my simulation to the end, no waveform is displayed and its value is displayed as "No Value Available".

Has anyone got any idea why my data member has no waveform?

Thanks for any help!
