Is SYNTHESIS, ASIC_SYNTHESIS Flag needed during Synthesis

[vignajeth]

Hi,
   I notice in a lot of places in the entire pulpisismo code that contains ifndef depending upon the flag SYNTHESIS, I also notice ASIC_SYNTHESIS flag being used inside the Ri5cy.
I also find PULP_TRAINING flag in the code

 Example in soc_peripherals.sv

`ifdef PULP_TRAINING
`ifndef SYNTHESIS

    apb_dummy_registers  #(.APB_ADDR_WIDTH(APB_ADDR_WIDTH)) i_apb_dummy_reg_unit (
        .HCLK       ( clk_i                   ),
        .HRESETn    ( rst_ni                  ),
        .PADDR      ( s_apb_dummy_bus.paddr   ),
        .PWDATA     ( s_apb_dummy_bus.pwdata  ),
        .PWRITE     ( s_apb_dummy_bus.pwrite  ),
        .PSEL       ( s_apb_dummy_bus.psel    ),
        .PENABLE    ( s_apb_dummy_bus.penable ),
        .PRDATA     ( s_apb_dummy_bus.prdata  ),
        .PREADY     ( s_apb_dummy_bus.pready  ),
        .PSLVERR    ( s_apb_dummy_bus.pslverr )
    );

`endif
`endif

should these flags be passed through the synthesis as a macro ?
