QSYS simulation using Avalon-MM BFM

Hello. I'm trying to run a simulation, using a testbench, generated with QSYS: 

// qsys_mod_tb.v // Generated using ACDS version 17.0 595 `timescale 1 ps / 1 ps `define BFM qsys_mod_inst.mm_master_bfm_0 module qsys_mod_tb ( ); wire qsys_mod_inst_clk_bfm_clk_clk; // qsys_mod_inst_clk_bfm:clk -> wire qsys_mod_inst_reset_bfm_reset_reset; // qsys_mod_inst_reset_bfm:reset -> qsys_mod_inst:reset_reset_n qsys_mod qsys_mod_inst ( .clk_clk (qsys_mod_inst_clk_bfm_clk_clk), // clk.clk .reset_reset_n (qsys_mod_inst_reset_bfm_reset_reset) // reset.reset_n ); altera_avalon_clock_source# ( .CLOCK_RATE (50000000), .CLOCK_UNIT (1) ) qsys_mod_inst_clk_bfm ( .clk (qsys_mod_inst_clk_bfm_clk_clk) // clk.clk ); altera_avalon_reset_source# ( .ASSERT_HIGH_RESET (0), .INITIAL_RESET_CYCLES (50) ) qsys_mod_inst_reset_bfm ( .reset (qsys_mod_inst_reset_bfm_reset_reset), // reset.reset_n .clk (qsys_mod_inst_clk_bfm_clk_clk) // clk.clk ); // Simple check initial begin `BFM.init(); `BFM.push_command(); // <--- This line causes the error $stop(); end endmodule 

This compiles well, but elab yields the error: 

# ** Error: (vsim-8220) ./../qsys_mod_tb/simulation/qsys_mod_tb.v(37): This or another usage of 'qsys_mod_inst.mm_master_bfm_0.push_command' inconsistent with 'function' object.# Time: 0 ps Iteration: 0 Instance: /qsys_mod_tb File: ./../qsys_mod_tb/simulation/qsys_mod_tb.v 

inconsistent with 'function' object?? What? 

Moreover any call to BFM API task, except for the BFM.init, leads to the same result. 

Appreciate any help.

Ok, I've found that qsys generated testbench was compiled without -sv flag enabled. My solution: sel USER_DEFINED_COMPILE_OPTIONS -sv
