VHDL design group creates firmware for COMBO6 cards. Our firmware supports many functions which utilize FPGA and CPLD technology. We use FPGAs that contain millions of gates on the same chip. Every gate can be utilized for specific function and can work in parallel. This give us strong computational power which can be used for time critical functions and enables COMBO6 cards to achieve high performance in many applications.

All firmware are writen in VHDL language which was developed for simulation and nowadays is also widely used for synthesis. Currently we support following projects:

• FlowMON probe - Flexible flow monitoring system
• Flexible FlowMON - Advanced Scalable passive flow monitoring system
• NetCOPE - Combo6x - General platform for rapid development of network applications on our main hardware card - Combo6x
• NIC - NetCOPE - Network Interface Card based on NetCOPE platform
• NIFIC - NetCOPE - Network Interface Filtration Card based on NetCOPE platform
• Intrusion detection system - Hardware accelerated Intrusion Detection System

Development of hardware components in VHDL languages is time consuming. For this reason we prepared set of generic (common) components that enables us speed up the design process. Documentation of generic components, all our components and several important sets of components are accessible by following links:

• IP cores - IP cores, that are used in our projects
• Generic components - small generic components, that are used in our IP cores
• FrameLink tools - documentation for FrameLink tools
• Interconnection System - documentation for Interconnection System
• Flow Context - Flow management system
