Can the XilinxIP: cdn_axi_bfm:5.0 still be used in Vivado 2017.3

Jump to solution

All,

 

I am migrating a design from Vivado V2015.4 to V2017.3 for a client.  Most of it is moving but this design still used the "licensed" CDN_AXI_BFM model for simulations and of course all the simulation scripts are written assuming this model.

 

So the question is can I still access this Xilinx IP in this version, I tried to "create_bd_cell" in the Block Design and it said that this IP is not found.  Is it found in another included IP Library?

 

Just trying to complete the port of this design so that it works the same as it did in the prior release.

Hi @tessitd

 

"cdn_axi_bfm" IP was obsoleted from Vivado 2017.1.

However, Xilinx has already released ZYNQ VIP and AXI VIP instead of "cdn_axi_bfm" IP from Vivado 2017.1

So, you can use AXI VIP instead of "cdn_axi_bfm" IP.

Would you refer the following URL, if necessary ?

 

# ZYNQ VIP (DS940)

# AXI VIP v1.1 (PG267)

Best regards,

Thanks for the quick reply, it is really a matter of migrating the verification framework to use the different VIP.  I haven't looked into it how the API has changed, but I am sure it has so there will be some work.

 

For my usage I actually export my design out to QuestaSim, I do still have the CDN_AXI_BFM for that but I had been relying on Vivado to do a Export For Simulation of the Project to produce an RTL design I could use.  Without the ability to instanciate the CDN_AXI_BFM in the block diagram that flow is lost to me.  For me the CDN_AXI_BFM replaces the AXI2JTAG BFM for my simulation usage.

 

So we had build quite a structure around this flow.  I will have to investigate a little more to understand the ramifications, for now I an still use V2015.4 to export the design as not much RTL is changing.
