A.3.10. av_mm_transaction
The av_mm_transaction class is the base class for an Avalon-MM transaction (command), including member variables for address, data, read or write, and byte enable values.
Method Call | Description |
---|---|
function new(int max_args); | Class constructor. max_args is only used during the randomization process as a maximum number of arguments. It does not limit how many arguments you can assign to the class. |
function void copy(av_mm_transaction #(ADDR_WIDTH, BYTE_WIDTH , USE_BYTE_ENABLE) val_to_cpy); | Deep copy from val_to_cpy into class. |
function cmd get_cmd(); | Returns the current command (READ or WRITE). |
function void set_cmd(Cmd cmd); | Sets the current command (READ or WRITE). |
function longint get_address(); | Returns the read/write address. |
function void set_address(longint addr); | Sets the read/write address. |
function int num_args(); | Returns the number of arguments (1 argument corresponds to 1 data beat on the bus). |
function void set_num_args(int length); | Sets the number of arguments. |
function int byte_enable_length(); | Sets the number of byte enables – used for writes whose bytes are not modulo BYTE_WIDTH in size. |
function void print_config_one_arg_per_line(bit one_arg_per_line); | If called with an argument of 1, any following calls to ps_printf will print the details for each argument (beat on the bus) on a new line. |
function string ps_printf(string indent_each_line_with); | Prints the entire command. |
function bit args_match(av_mm_transaction #(ADDR_WIDTH, BYTE_WIDTH, USE_BYTE_ENABLE) cmp); | Compares cmp against the av_mm_transaction object and returns a 1 if the number of arguments and value of each argument in a message match. Called by the equals method call. |
function bit byte_enable_match(av_mm_transaction #(ADDR_WIDTH, BYTE_WIDTH, USE_BYTE_ENABLE) cmp); | Compares the byte enable values in cmp against the av_mm_transaction object’s byte enable values and returns a 1 if the number of byte enables and values match. Called by the equals method call. |
function bit equals(av_mm_transaction #(ADDR_WIDTH, BYTE_WIDTH, USE_BYTE_ENABLE) cmp); | Compares cmp against the av_mm_transaction object and returns a 1 if they are identical. |
Member | Description |
---|---|
int c_max_args; | Maximum number of arguments for constrained random generation. |
rand enum { READ, WRITE } cmd; | The command itself (read or write). |
rand bit [ADDR_WIDTH-1 : 0] addr; | Address. |
rand bit [BYTE_WIDTH*8-1 : 0] arguments [$]; | Arguments / data beats. |
rand byte byte_enable [$]; | Byte enable bus values. |
