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.
