SPI Slave Implementation

I am writing a code of SPI slave in FPGA. Is it necessary to sync my FPGA global clock and serial clock ? If so can someone tell me the pros & cons for the same ?

Thank You very much for your valuable reply...!

I have some another question! Is it necessary to use CS(Chip Select) signal in SPI ? If I am using only one slave then can I connect this CS pin to ground permanently ?
