If you are referring to Verilog, then yes, many synthesis tools support "parameter".
Your software user manual should explain which Verilog features are supported.
If you are using Xilinx ISE, then refer to the "XST User Guide" chapter "Verilog Language Support".
That chapter and the "HDL Coding Techniques" chapter are a good way to learn Verilog for Xilinx devices.
