protected altera_xcvr_atx_pll_ip_inst

Dear All,

Today i built the testbench http://www.alterawiki.com/wiki/single_port_ll_ethernet_10g_mac_with_1588_using_native_phy_design_example, in ModelSim. It compiled fine until :

# Loading work.avalon_st_eth_packet_monitor

# ** Fatal: Error occurred in protected context.

# Time: 0 ps Iteration: 0 Protected: /tb_top/DUT/atx_pll_inst/altera_xcvr_atx_pll_ip_inst/<protected> File: nofile

# FATAL ERROR while loading design

# Error loading design

# Error: Error loading design

# Pausing macro execution

# MACRO ./testbench/tb_run_simulation.tcl PAUSED at line 76

Apparantly the file altera_xcvr_atx_pll_ip_inst is protected and encrypted.

Does anyone have a suggestion how to make this file available?

Thanks
