Question regarding IP-XACT Bus Definition of AMBA5 AHB5Initiator

kangho Lee

Hello, 

I'm kangho Lee managing IP-XACT bus definiton in my company.

I can't create issue to Contact Support (arm.com) with unknown error. so I borrow this page.

I have a question regarding IP-XACT Bus Definition of AMBA5 AHB5Initiator.

My company's engineer is provided IP and bus definition [amba.com AHB5 Initiator r0p0_0] from ARM. An AHB5Initiatior is used in that IP.

But I found that revision of bus definition is defferent with my managed one and port list and port element value are different also.

I write related information of bus definition and abstraction definition of AHB5 Initiator below.

The revision 0 and revision 2 don't have compatibility. so I think revision 0 and revision 2 are different abstraction definition but they have same VLNV [amba.com AMBA5 AHB5Initiator r0p0_0]

It's unable to change abstraction definition from revision 0 to revision 2 because Many IP are already designed IP with revision 0.

Can you confirm this?

description AHB5 initiator updated according to spec ARM IHI 0033B.b (ID102715). The bus definition is intended to use with interfaces associated with initiator device connections (those between the bus master and the interconnect). This is an update to the AHBLite features released with AMBA3. It improves memory type support (HPROT on 7 bits), HMASTLOCK can be asserted with different schemes, secured, locked and exclusive transfers are now supported with additional signals. Atomicity is also introduced. AHB5 initiator according to spec ARM IHI 0033C. The bus definition is intended to be used with interfaces associated with initiator device connections (those between the master and the interconnect).Reference: AMBA AHB Protocol Specification ARM IHI 0033C www.arm.com/.../AMBA.html port list HCLK HCLK HCLK
