chipscope synchronize data
Well, you didn't tell us much about your bitstream.
You can synchronize it by taking the clock that is driving the device that is generating the bitstream and feeding it to your FPGA. Then you'd use a PLL or DCM to drive the circuitry that will latch your bitstream. This will also require you do make sure you distribute that clock carefully on the board to minimize skew.
Or, your bitstream might be source synchronous, where the clock is sent along with the data, and you would use that clock to sample the bitstream.
Or, if the bitstream's clock is not available, you have an asynchronous interface, and you'll have to use a much higher rate clock than the data was generated with, and sample the bitstream and detect the data edges and reconstruct the data yourself. RS232 works something like this.
Chipscope is a debugging tool for the lab, and is meant to be used with the Chipscope software.
