Description You may see the following Qsys warnings when if you open a Quartus® II 13.0sp1 version of a Stratix® IV GX/T Transceiver Toolkit example designs: Warning: xcvr_low_latency_phy_0: Used altera_xcvr_low_latency_phy 13.0 (instead of 100.99.98.97) Warning: System.xcvr_low_latency_phy_0: Upgrade from Low Latency PHY 11.0 is not supported. Please create new IP variant. Resolution To eliminate these warnings, follow these steps: Unarchive Transceiver Toolkit example design. Copy the \'ip\' directory from /siv_4ch_10b_2500mbps to the main project directory created in step 1. This problem will be fixed in a future version of the Stratix IV GX/T Transceiver Toolkit example designs.
