Qsys and XCVRs

Hi,

opening the aii_4ch_10b_2000mbps design example and starting the Qsys tool, I can see that there is a xcvr component. If I want to add an additional xcvr I don't know how to proceed. I don't find any xcvr component in the library components shown on the left tree control. My goal is to have a couple of transceiver with different speed.

Thank you,

Antonio.
