altera_avalon_mm_slave_bfm question

HI, 

 

I use QSys to add a "MM Slave BFM" in the tb and my mm master module only reads data from it. The tb reports many "Pipeline read command XX > AV_MAX_PENDING READS 1" errors.  

 

After reading bfm source code, I find that as long as "read" signal of mm master is asserted, bfm generates a new read command and insert it in the queue. But actually, they belong to the same burst read.  

 

I try to find a way to clear those "extra" command. Any idea? Or do I misunderstand something? 

 

Thanks, 

John
