Xilinx VIRTEX II pro: ug024

[voho]

Hi,

Rocket IO sheet 33 of ug024.
How i can Attribute Defaut Values: GT_FIBRE_CHAN in vhdl code.

begin

ALIGN_COMMA_MSB<=false;
......
......
TX_PREEMPHASIS<=0;

end;

Thank's in advance

It's not the attribute. It's a type of transceiver. You can use Architecuture Wizard to generate the component in VHDL. Such as..

component GT_FIBRE_CHAN_2
generic(
CLK_COR_INSERT_IDLE_FLAG : boolean := FALSE;
CLK_COR_KEEP_IDLE : boolean := FALSE;
CLK_COR_REPEAT_WAIT : integer := 2;
REF_CLK_V_SEL : integer := 0;
RX_CRC_USE : boolean := FALSE;
RX_LOS_INVALID_INCR : integer := 1;
RX_LOS_THRESHOLD : integer := 4;
RX_LOSS_OF_SYNC_FSM : boolean := TRUE;
SERDES_10B : boolean := FALSE;
TERMINATION_IMP : integer := 50;
TX_CRC_FORCE_VALUE : bit_vector := "11010110";
TX_CRC_USE : boolean := FALSE;
TX_DIFF_CTRL : integer := 500;
TX_PREEMPHASIS : integer := 0
);

Hi elektrom and everybody :sm5:

Thank's for your help.

What do you do about the other signal. :idea:
The other signal is not necessary :?:

COMPONENT GT_CUSTOM
generic (
ALIGN_COMMA_MSB : BOOLEAN := FALSE ;
CHAN_BOND_LIMIT : INTEGER := 1 ;
CHAN_BOND_MODE : string := "OFF" ;
CHAN_BOND_OFFSET : INTEGER := 0 ;
CHAN_BOND_ONE_SHOT : BOOLEAN := TRUE ;
CHAN_BOND_SEQ_1_1 : std_logic_vector(10 downto
0) := "00000000000" ;
................
................
CHAN_BOND_SEQ_2_4 : std_logic_vector(10 downto
0) := "00000000000" ;
CHAN_BOND_SEQ_2_USE : BOOLEAN := FALSE ;
CHAN_BOND_SEQ_LEN : INTEGER := 1 ;
CHAN_BOND_WAIT : INTEGER := 7 ;
CLK_CORRECT_USE : BOOLEAN := TRUE ;

CLK_COR_SEQ_1_1 : std_logic_vector(10 downto
0) := "00110111100" ;
...................
CRC_FORMAT : string := "FIBRE_CHAN" ;
....................
);

Hi everybody,

I have a type of transceiver: coaxial cable. I use Architecuture Wizard to generate the component in VHDL. BUT in select transceiver he purpose:

Aurora
Custom
Ethernet
Fibre Chanel
Infiniband
XAUI

For coaxial cable is XAUI or ..... :?: :?: :?: :?: :?:

Regards

Hi


More info my electric diagram about coaxial cable

Thank's in advance

Maybe you can select GT_CUSTOM to custom your coaxial cable.
of cause , you can refer with XAUI
