In virtexii-pro, icap is in the right down corn of fpga. Where is it in virtex-4 ? How can i locate it using fpga editor ?

 

 

Thanks.

 

 

Jardel.

Hi,

UG071 Page 99 shows how the things are going in case of Virtex4.
It's worked for me.
In case of Virtex II it should work too.
I am unsure about "Desync command" support on VirtexII.
Other steps are supported since the plain old Virtex devices (READ
XAPP151 too).

Good luck,
Gyuri
