pcie phantom support

Hi,

Im using a pcie core generated in the past that doesnt support phantom functions.

i know this because of:

parameter integer DEV_CAP_PHANTOM_FUNCTIONS_SUPPORT = 0,

 

Now i want my design to support phantom functions so i changed the line to 

parameter integer DEV_CAP_PHANTOM_FUNCTIONS_SUPPORT = 3,

 

But if i send a request tlp and put something that not 0 in the requester ID function number field, my design just doesnt get any response back.

 

Is there somthing else i need to change in order to support phantom function?

Re: pcie phantom support

Im using vc707 virtix7 device

the core version is 1.7

The difference between me and the link is that im using a core that was already created and i want to know if i have to change anything else besides what i did.

 

Thanks
