PCI Express

[jeffzhang]

Hi,

I am trying to simulate PCIe BMD for SP605 with ISim 13.2. I got a problem that PIO operation doesn't happen once Bus Master bit set. Here is my tests.vhd:

    elsif (test_selector = String'("bmd_write_test")) then

      writeNowToScreen(String'("Running bmd_write_test"));

      PROC_SYSTEM_INITIALIZATION(trn_reset_n, trn_lnk_up_n);

      PROC_BAR_INIT (tx_rx_read_data_valid, rx_tx_read_data_valid, rx_tx_read_data, trn_td_c,
        trn_tsof_n, trn_teof_n, trn_trem_n_c, trn_tsrc_rdy_n, trn_lnk_up_n, trn_tdst_rdy_n, trn_clk);

      PROC_TX_CLK_EAT(300, trn_clk);

        -- Set the DMA(2) and Interrupt(10) bit in cfg_command
        write (Lglobal, String'(" Writing cfg_command REG "));
        --hwrite(Lglobal, std_logic_vector(to_unsigned(i, 4)));
        writeline (output, Lglobal);

        PROC_TX_TYPE0_CONFIGURATION_WRITE (
          X"06", x"004", x"00000404", X"F",
          trn_td_c, trn_tsof_n, trn_teof_n , trn_trem_n_c, trn_tsrc_rdy_n,
          trn_lnk_up_n, trn_tdst_rdy_n, trn_clk);

        PROC_TX_CLK_EAT(5000, trn_clk);

        -- Assert Initiator Reset
        write (Lglobal, String'(" Writing DCR1 With 0x01 "));
        --hwrite(Lglobal, std_logic_vector(to_unsigned(i, 4)));
        writeline (output, Lglobal);

        DATA_STORE(0) := X"01";
        DATA_STORE(1) := X"00";
        DATA_STORE(2) := X"00";
        DATA_STORE(3) := X"00";

        PROC_TX_MEMORY_WRITE_32 (
          X"07", "000", "0000000001", BAR(0)(31 downto 0), X"0", X"F",'0',
          trn_td_c, trn_tsof_n, trn_teof_n , trn_trem_n_c, trn_tsrc_rdy_n, trn_terrfwd_n,
          trn_lnk_up_n, trn_tdst_rdy_n, trn_clk);

        PROC_TX_CLK_EAT(100, trn_clk);

    ......(other BMD register operation)

        -- Write DMA Start
        write (Lglobal, String'(" Writing DCR2 With 0x01 "));
        --hwrite(Lglobal, std_logic_vector(to_unsigned(i, 4)));
        writeline (output, Lglobal);

        DATA_STORE(0) := X"01";
        DATA_STORE(1) := X"00";
        DATA_STORE(2) := X"00";
        DATA_STORE(3) := X"00";
        addr := std_logic_vector(unsigned(BAR(0)(31 downto 0)) + X"04");
        PROC_TX_MEMORY_WRITE_32 (
          X"0d", "000", "0000000001", addr, X"0", X"F",'0',
          trn_td_c, trn_tsof_n, trn_teof_n , trn_trem_n_c, trn_tsrc_rdy_n, trn_terrfwd_n,
          trn_lnk_up_n, trn_tdst_rdy_n, trn_clk);

        PROC_TX_CLK_EAT(100, trn_clk);

From ISim only first two PIO operations happened. rest of them didn't happen. Once I move cfg_command writing operation down to bottom after BMD config operation, it seems I can see all BMD config operations. but another problem happened that is the second DMA will not happen becuase any PIO operation after first DMA will not happen. What am I missing here?

Thanks,

Jeff

Have your double checked that there's nothing else stopping your simulation? Sometimes a test bench will have a timeout counter that will stop the simulation before you actually want it to stop.

Can you also upload ISIM's transcript?

thanks for your reply. here is message from ISim Console:

# restart

there is no error during simulation. but the DMA did not happen.
