2013.2 Vivado IP Integrator - "ERROR [BD 41-237] Bus Interface property FREQ_HZ does not match between /mig_7series/S_AXI() and interconnect_1/s00_couplers/M_AXI()"


In a simple Vivado IP Integrator system with a mig_7series, IP connects to an external AXI interface via a AXI Interconnect. However, during Generate Output Products, an error similar to the following occurs:

ERROR [BD 41-237] Bus Interface property FREQ_HZ does not match between /mig_7series/S_AXI(166250000) and interconnect_1/s00_couplers/M_AXI(10000000)

How can I fix this issue?


If an AXI interface is made external, the FREQ_HZ property will default to 100MHz. So, you will have to manually update this in the External Interface Properties for the AXI, and the External Port Properties for the S00_ACLK.

In the example above, you need to change this to 166250000.

To change the FREQ_HZ property, highlight the external interface port in the block diagram and drop down the CONFIG, and modify the FREQ_HZ to the required Frequency in the External Port Properties GUI:

Repeat this for the External Port Properties too. Again, highlight the external clock port connected to the ACLK (in this example S00_ACLK).
