PCIe Endpoint to PCIe EndPoint communication

Is it possible to communicate between two pcie endpoint Hard IPs in FPGA. Do somebody tried it?Any references? the idea is to interface a PCIe device(can be a rootport) to pcie endpoint(in fpga) th...

Hi Sir,

Yes any EP device can initiate transaction to other EP through a bridge.

But what I am confusing here is you mentioned the FPGA EP will act as a bridge. I don't think we can use the FPGA as a bridge.

So, in your application, you will still need a physical bridge that connecting the 2 EP.

BCT_Intel..thanks for the reply.

its just a misunderstanding about the bridge that i mentioned in my query.sorry for that.

In some intel fpga i found 2 Hard PCie IP.

my question , is it possible to connect these 2 IPs which are configured as ENDPoint, So that one PCie EP receive the data from a RP and other EP will transfer data to another RP.

Do u have some reference designs for this..

you mentioned about bridge is the cutom design(eg: dual port Ram) which need to be interfaced with these 2 Endpoints .Correct me if I am wrong?
