If I can use FPGA to realize the goal of ultra-high speed counts

I want to use the FPGA to realize the goal of high speed counter，which can count 10G pulse per second. Would you please tell me which series of the altera can make it ？ How to realise t...

Ok, I am thinking something like performing clock slicing using PLL. For example, if the FPGA core is running at 200MHz, you will need to slice 50 times to get 10GHz. In this way you need to create 50 clocks with phase shifted by 7.2 degrees each to achieve the 10G pulse sampling rate.
