Hi,


I saw when slave_0_address is c0, the slave_0_writedata is ff. Do you mean the slave_0_write is not being asserted? Have you checked that there's proper connection between your avalon slave and avalon mm master bfm.

I think the push a command code should be no problem else master bfm wouldn't have proper waveform.

I notice the master bfm waitrequest, have you enable the Assert waitrequest high for master bfm?


Thanks,

Best regards,

Sheng

I think there is a proper connection between master and the slave. I generated using the qsys. Can we check if it's proper in any other way?

I think I didn't assert waitrequest high but in the waveform, the mo_waitrequest is being asserted towards the end of it right? Is it because not asserting it high?

    In qsys, for the avalon mm master bfm, I had enabled assert wait request high. I had checked it again.
