Accessing sequencer methods from virtual sequence using p_sequencer

[hmeiners]

Within a virtual sequence running on a virtual sequencer I try to get data from a uvm_tlm_analysis_fifo that is created in the virtual sequencer.

However calling the blocking get of the FIFO through the p_sequencer directly:

p_sequencer.fifo.get(tr);

or through a member task that is declared in the virtual sequencer:

p_sequencer.get_tr(tr)

is working correctly. Basically, the blocking get() never returns a value. The fifo is connected correctly and I was able to call fifo.get() directly in the virtual sequencer e.g. by calling fifo.get() in run_phase().

What's wrong?

Hi,

I am afraid that we can't help you with the information that you have provided. Here is an idea: You have a deadlock inside your virtual sequence that goes through a non-virtual sequence, a driver, the analysis fifo, the virtual sequencer and back to the virtual sequence.

It is a long shot. I hope this helps.

Peter,

basically it was my fault. I started the sequence in the "wrong" phase w/o any objection. Thus, the sequence was killed before getting the data from the sequencer.

Thanks,

Holger
