Not detecting the right JTAD ID for EYE810-XXVAM2

[nclermon]

Hello,

I am developing JTAG test on one of our board that use the Ethernet Controller EYE810-XXVAM2. I have 6 differents chains and the only one I am not able to test is the chain that have the EYE810 connected to it. I'm not able to test the infrastructure and the interconnect on the chain with the EYE810 device. I can't read the ID of any of the devices on this chain. I am suspecting a wrong BSDL file or the JTAG configuration of EYE810. Base on the datasheet the TAP_SEL pin should be connected to a pull-up if it's connected to a manufacturing TAP. We have connected directly our JTAG controller to the JTAG pins of the EYE810 without any TAP so the TAP_SEL is connected to a pull-down.

We have develop a script with a Lattice dongle that is able to read the JTAG ID of each device without using the infrastructure test from the JTAG GUI. The only device that the JTAG ID is not the same as the one on the BSDL file is the EYE810 device. Every other devices ID is the same as their BSDL file.

With the Lattice dongle I read this ID :

0001 0000 0000 1100 0000 0001 0001 001 1

I don't have any other Intel chip in my library so I can't compare the Manufacturer ID bits.

I use BSDL file cvl_top_pkg_SD_B0.BSDL and the JTAG ID from the BSDL is :

attribute IDCODE_REGISTER of cvl_top : entity is
"0010" & -- Part version bits (31-28)
"1010000110010101" & -- Part number bits (27-12)
"01010111111" & -- Manufacturer identity bits (11-1)
"1" ; -- mandatory LSB value (0)

The other package BSDL for the E810 I have is : cvl_top_pkg_B0.bsdl and cvl_top_pkg_C0.BSDL but the pinout is not good and the JTAG ID is not the same I read with the Lattice dongle.

Did I need to use another BSDL file for our EYE810-XXVAM2_SLNG2 ?

Let me know if you need more details.

Thanks

Nicolas
