We have the following questions related to Virtex 4 configuration frames:
a). What is the shape and size of a frame in Virtex 4 device? In Virtex2, each frame is contained in one vertical column of the device. But we could not find any information related to the shape of frame in Virtex 4.
b). How many CLBs does one frame include or vice versa?
c). In one datasheet, it is written that Virtex 4 is a tile based device. Does it mean that each configuration frame is completely contained in one tile? If yes, how many frames/CLBs does one tile contain?
d). Can we use the Xilinx JBits SDK to configure a Virtex 4 frame? The documentation for JBits 3.0 does not refer to Virtex 4 and only seems to support Virtex 2. If it doesn't support Virtex 4, what is the equivalent toolkit for Virtex 4 devices?
Please do help as we could not find information related to this in Xilinx website or in newsgroups.
Thanks in advance, Love Singhal
