[SOPC Builder] Connect 2 Avalon ST interfaces with different clock domains

[Altera_Forum]

Is there an easy way to connect 2 Avalon ST interfaces each with its own clock domains? 

 I expected there should be a ST adapter will do the job but look like there is no such thing.  Advice please!

Just put a dual-clock FIFO in between them. This is how it's done throughout the Avalon ST based components. Use the rdempty signal on the read side to provide your valid signal. Use the wrfull signal on the write side (and maybe wrusedw depending on the ready latency) to provide the ready signal. 

 Can't get easier than that. Probably take you all of 10 minutes to code. Be sure to pass the startofpacket, and endofpacket and any other needed signals through the FIFO.  Jake

Thanks Jake, I am wondering if you have time for yourself instead of helping people out around here.:)

Hi, 

 I need crossing two synchronous clock domain for Avalon-ST First, Avalon-ST source has clock 100MHz Second, Avalon-ST sink has clock 50MHz (100 / 2) Both clock are synchronous. Is possible crosing without DCFIFO ?   Regards, Rob.
