Procedure tb_read_descriptor
The procedure tb_read_descriptor reads a receive descriptor into shared RAM, issued from the testbench. It is defined
below:
procedure tb__descriptor (
signal
signal
signal
signal
desaddr
des0
des1
des2
des3
clk
re
raddr
rdata
: in std_logic;
: out std_logic;
: out std_logic_vector(DATADEPTH-1 downto 0);
: out std_logic_vector(DATAWIDTH-1 downto 0);
: in integer;
: out integer;
: out integer;
: out integer;
: out integer
)
The string marks is displayed at beginning of the information, clk is the CLKDMA, desaddr is the beginning address of
the descriptor, re is the read enable issued from the testbench, raddr is the read address to shared RAM issued from the
testbench, rdata is the read data to the testbench, and des0, des1, des2, and des3 are the four 32-bit words of the
descriptor.
Procedure tb_read_check_descriptor
The procedure tb_read_check_descriptor reads a receive descriptor from shared RAM, issued from the testbench and
checked it against sequential data starting from 0 and incrementing with a step size of 1. It is defined below:
procedure tb_read_check_rx_data (
count
: in integer;
signal
signal
signal
signal
clk
re
raddr
rdata
: in std_logic;
: out std_logic;
: out std_logic_vector(SHRAMDEPTH-1 downto 0);
: in std_logic_vector(SHRAMWIDTH-1 downto 0);
ra
signal error
: in integer;
: inout integer
)
The CLKDMA is clk, desaddr is the beginning address of descriptor, re is the read enable issued from the testbench,
raddr is the read address to shared RAM issued from the testbench, rdata is the read data to the testbench, count is the
number of bytes, ra is the read address, and error is the error counter, which is incremented by the total number of
mismatches.
