Behavior of Request/Grant signals on Tristate Interface

Hi all,

I wrote a custom Tristate Conduit Master (TCM) and connected it to a TC Pin Sharer. Monitoring the behavior of the request and grant signals, I see that I loose two clock cycles, because request is only granted two cycles later:

According to the avalon tri-state conduit componen user guide (http://www.altera.com/literature/ug/ug_avalon_tc.pdf), grant should be asserted immediately is shown in figure 3-4:

--- Quote Start ---

Because request is deasserted in the final cycle of a bus access, it can be reasserted

immediately following the final cycle of a transfer, making both rearbitration and

continuous bus access possible if no other masters are requesting access.

--- Quote End ---

Does anybody know, why I get this delay?

=> PS: No, there is no other master requesting access.

Thanks

Simon
