Interface RapidIO Microblaze

Hi,

I am using ISE.

I would like to send and receive packets with a microblaze connected to an Ip SRIO gen2 v1.6. I have an AXI-stream Interface (AXIS_M0 & AXIS_S0) my ublaze and condensed I/O on the SRIO (iorx & iotx).

The problem I have is that the microblaze has a clock of 100Mhz and the logical interface on the SRIO is at 39.06Mhz (1x and 3.125Gps). How can I resolve this issue? What's more some signals on the condensed I/O like tuser and tkeep are not present.

 

Thanks

Re: Interface RapidIO Microblaze

I'd like to but I have a Virtex 6. On the post, it only connects the maintenance port thanks to an AXI (lite) interconnect. I'd like to connect both the I/O and maintenance ports to the ublaze, so that means I should use one AXI interconnect and one AXi stream interconnect? Would this resolve the clock domains' difference?

Re: Interface RapidIO Microblaze

Hi K@ppa,

 

 

Did you successfully connect the RapidIO with Micro-blaze ?

Please let me know how did you connect the RapidIO with Micro-blaze, can you please share the design pictures or more details about the interface connections ?

 

I tried to connect RapidIO with Micro-blaze via AXI interconnect IP, but converting the AXIStream of SRIO ip to AXI4-lite.

But I am facing multiple issues ?


Can you please help me ?
