Xilinx XC95108 Chip

[Bose]

I wrote a VHDL program and loaded it into a Xilinx XC95108 chip ,
unfortunately , the chip's memory is unable to store the VHDL Program
.. The VHDL program size is too huge . I was wondering what's the
maximum number of Flip-flops & Gates the XC95108 can store ? I need
this information . Can anyone tell me ?

Thanks for the help .

Look in the data sheet.

The number of FFs should be simple. The number of gates
is (much) more complicated.

The 108 has 108 cells. Each has a FF.

One cannot load a VHDL program in a chip. What you load is a bitstream,
which results from running first synthesis and then several implementation
phases. If your design doesn't fit in a particular chip you know it when
your implementation fails in one of the phases. When this happens you don't
have a bitstream to load. So, I don't understand what and how you were
trying to load?...

Well, I ran all the programs ( running fc2,design manager ... )and
implementation and all phases were successful.It's only at the last
stage where I have this problem,the chip's memory size is too small to
store my vhdl program.

By the way, the XC95108 has 108 cells , what are cells ? so the
sc95108 can store 108 flip-flops ?

Thanks for the help.

You really should read the data sheet.

The numbers in the suffix stand for macrocell count. So, a XC95108 woould
have 108 MCs. A MC contains a register, PTA (product term allocator) and a
switch matrix.
You should read the datasheet for more info. Also a "chip's memory size"
does not make any sense. The 9500s do not have any on-chip memory. Maybe you
meant that the device is over-utilized?
