In reply to jundijiujieke:
I guess the gnt signal comes out of the DUT. Right?
And what are you doing in your driver?
What is that
vif_tcdm.tcdm_addr = tr.tcdm_addr;
vif_tcdm.be = tr.be ;
vif_tcdm.req = tr.req ;
vif_tcdm.wdata = tr.wdata ;
vif_tcdm.wen = tr.wen ;
I guess your seq_item is here ‘req’.
And be, wdata etc are in your seq_item? Right?
