[OPT 31-30] blackbox xbar not found

Jump to solution

Hi,

 

in my project I have 8 AXIDMA blocks connected to the ACP port of the PS through an axi_mem_intercon.

Systhesis is fine but then I receive the error

ERROR: [Opt 31-30] Blackbox AXI_FFT_i/axi_mem_intercon/xbar (AXI_FFT_xbar_0) is driving pin D of primitive cell AXI_FFT_i/axi_mem_intercon/m00_couplers/auto_pc/inst/gen_axi4_axi3.axi3_conv_inst/USE_WRITE.write_addr_inst/S_AXI_ACACHE_Q_reg[3]. This blackbox cannot be found in the existing library.

 

I attach the tcl to regenerate the design and the synthesis and implementation logs.

 

Any suggestion?

 

 

Thanks,

Max

I instantiated the interconnect module manually, then run the automatic connection and now I am able to complete the implementation.

Hi max.giacometti@gmail.com,

 

Refer to this link and check if it helps:

Also check if you have a valid license for the IP.

 

Thanks,

Log has one blackbox module "AXI_FFT_xbar_0", but the shared file has no information on the commands and flow. Looks like opt_design is not able to find the black box module and hence showing an error.

I checked the AR, but that seems to be valid for user defined IPs, while the xbar is included in the axi_interconnect automatically generated while connecting ACP and DMA.

 

So might it be a licencing issue?

I am using vivado webpack edition and I didn't purchase any licence. The AXI interconnect page states that the IP is Included at no additional charge with Vivado and ISE Design Suite.

 

Or is there a maximum number of ports which can be connected for free?

In another project I have 2 AXIDMA connected to ACP through AXI interconnect and the implementation process is successful.
