BFM and Driver

Raviram80

Hi All,

 

Can someone tell me the difference between BFM and driver or is there no difference?

 

Also can someone point to me a good verification testbnech fundamental link or if there is a book you could recommend?

Thanks

  • Hi.

    In the eRM days, BFM was used to refer to the unit that converted from transaction objects to pin wiggling. eRM also used the term "driver" to refer to the sequencer unit that produces the stream of transactions.

    Now with OVM the BFM has been renamed to "driver",and the sequence driver is named "sequencer". I don't know the exact reason for the change, but I guess it was done to harmonise between the Cadence and Mentor libraries when OVM was created...

    As for methodology books / web links, if you have access to the Cadence SOC Verification Kit that comes with the INCISIV92 software, then there is a huge amount of info in there on all kinds of methodology and technology (Assertion-based, Formal, OVM, Specman, SystemC, SystemVerilog etc). If that's not enough to keep you busy for a while, then there are a few good books too, but they mostly specialise in one aspect of verification (e.g. OVM).

  • Thanks Stephen for this explanation.

    Is sequencer also called transaction generator which feeds the driver?

     

  •  We don't call it that, but yes, that's what it does! :-)

    The official OVM term is "sequencer".
