Use different AXI4-lite clock in system generator

I've built a waveform generator in system generator and I wanted to use a AXI4-Lite interface to set the settings for it. I've set the Implementation Interface on the Xilinx gateway blocks to "AXI4-Lite" which gives me the interface, however it is clocked at the rate of my waveform data generator (250 MHz). Is there anyway I can separate the clocks in system generator so that I can run the AXI4-Lite interface at 150MHz, while I run the waveform generation at 250 MHz? Or will I have to do a custom AXI wrapper over it to take care of this?

 

Thanks.

Re: Use different AXI4-lite clock in system generator

So how would I set this up? Put all the gateways in one clock domain, and everything else in the rest?
