VHDL Switch Debouncing on Cyclone FPGA

I need a software-based VHDL code for switch debouncing on a Cyclone FPGA. The purpose is to eliminate noise from mechanical switches, push buttons, or toggle switches.

Requirements:
- VHDL code implementation
- Compatible with Cyclone FPGA
- Effective debouncing for mechanical switches, push buttons, or toggle switches

Ideal Skills and Experience:
- Proficiency in VHDL
- Experience with Cyclone FPGA series
- Knowledge of switch debouncing techniques
