Re: [partial-reconfig] Problem with Bus macro in Virtex-II

[<jedward@xxxxxxxxxx>]

Thanks for your answers friends,

Now I have curiosity of like using XDL to modify to bus macro, because
I tried to use xdl (xdl -ncd2xdl bm_4b_v2.nmc) but i couldn´t modify a bus
macro as I want. I have the xdl´s of bus macros(Virtex and virtex II).
Can you explain me how i adding a PIP for the TBUF of TNET(3)?, but i
don´t know!
Thanks in advance
