    Controlling Hreadyin signal from AHB eVC Reply

    Hi,

        I have problem in controlling Hreadyin signal(to force it low randomly) from AHB eVC. Is there any existing sequence in versity's AHB eVC to create such scenario and also i am very thankful if anyone suggests me the other ways to control the Hreadyin signal.

    Thanks in advance
    --Srik.

    Hello Srik,

    the HREADY_IN is a result of the slave mux, the decoder and the HREADY_OUT signal of the responding slave. If this slave is controlled by an active agent from the eVC, you can control it's HREADY_OUT by using the delay field of the slave response or settings for reset. Have a look in the AHB eVC documentation (looking for HREADY and delay ).

    Regards,

    You can find the AHB eVC on the Cadence downloads site.
    Please be aware though that it's a commercial product and needs a licence before you can run simulations.

    RE: Controlling Hreadyin signal from AHB eVC Reply

    Hi Guys,
    Now i'm doing testcase for mux, dec and arbiter for 2 Master and 1 slave env buses.
    I want to ask one question, let us say current transfer is M1 and the M2 requesting and also granted. but granted master getting address and data access control after some cycles or depends on previous master data control with hready. So is this is proper activity.

    My slave does not support split transfer. is this related with retry transfer. can u give me details abt retry transfer.


    Can you please reply me.
    Thanks a lot.

    Hi, I'm not sure if this will help, but, you can find information about how split transfers work in:
    http://infocenter.arm.com/help/topic/com.arm.doc.ihi0011a/IHI0011.pdf
    section 3.12

    As to the scenario you described, I'm not sure I exactly understand what you have written. Since I'm not an AHB expert, I think I will let some of the other users answer that...

    Cheers,
