Hello SK,

I answered you by email but I do not know if you received it so I answer here as well:

No I am trying to read the Vendor ID of the Root Port as it is made in the simulation file attached, line 170.

That is why ID Bus Device Function = 0, this is to access the Vendor ID of the Root Port.

I can send you a test case if you want.

Can you have a look to the Signal Tap file attached you will see the sequence.

Thanks for help.
