DE10Pro-bsv-shell

A Bluespec SystemVerilog Interface definition for DE10Pro projects. It defines a set of sub-interfaces exposing some of the devices available on the board to the code implementing the interface.

Available sub-interfaces

H2F_LW

interface AXI4Lite_Slave #( t_h2f_lw_addr
                          , t_h2f_lw_data
                          , t_h2f_lw_awuser
                          , t_h2f_lw_wuser
                          , t_h2f_lw_buser
                          , t_h2f_lw_aruser
                          , t_h2f_lw_ruser ) axls_h2f_lw;

An AXI4 Lite slave port receiving requests from the ARM HPS embedded on the FPGA.

H2F

interface AXI4_Slave #( t_h2f_id
                      , t_h2f_addr
                      , t_h2f_data
                      , t_h2f_awuser
                      , t_h2f_wuser
                      , t_h2f_buser
                      , t_h2f_aruser
                      , t_h2f_ruser ) axs_h2f;

An AXI4 slave port receiving requests from the ARM HPS embedded on the FPGA.

F2H

interface AXI4_Master #( t_f2h_id
                        , t_f2h_addr
                        , t_f2h_data
                        , t_f2h_awuser
                        , t_f2h_wuser
                        , t_f2h_buser
                        , t_f2h_aruser
                        , t_f2h_ruser ) axm_f2h;

An AXI4 Master port sending requests to the ARM HPS embedded on the FPGA.

DDRB

interface AXI4_Master #( t_ddrb_id
                       , t_ddrb_addr
                       , t_ddrb_data
                       , t_ddrb_awuser
                       , t_ddrb_wuser
                       , t_ddrb_buser
                       , t_ddrb_aruser
                       , t_ddrb_ruser ) axm_ddrb;

An AXI4 Master port to reach the DDR B channel.

DDRC

Defined similarly to DDRB.

DDRD

Defined similarly to DDRB.

TX / RX links

interface Source #(t_link_tx) tx_north;
interface   Sink #(t_link_rx) rx_north;
interface Source #(t_link_tx)  tx_east;
interface   Sink #(t_link_rx)  rx_east;
interface Source #(t_link_tx) tx_south;
interface   Sink #(t_link_rx) rx_south;
interface Source #(t_link_tx)  tx_west;
interface   Sink #(t_link_rx)  rx_west;

TX and RX link to be routed to the external links of the DE10.

Interrupts

interface Vector #(32, Irq) irqs;

A vector of 32 interrupt lines coming out of the implemented design, typically to be routed to the HPS.

Intended use

The design can use the DE10Pro_bsv_shell interface and provide an implementation of the individual sub-interfaces. The toDE10Pro_bsv_shell_Sig module can then be used to retreive a DE10Pro_bsv_shell_Sig interface which exposes signals with appropriate names for further usage in EDA tools (for example Quartus, with the help of the vipbundle tool).

A trivial example implementation of the interface, mkPassThroughToDRAMDE10Pro_bsv_shell, can be found in DE10Pro_bsv_shell.bsv.
