FPGA implementation 

This section gives some technical details about the FPGA firmware. 

Language 

Sundance uses Aldec Active-HDL tool for the design entry and the simulation.  
The FPGA is fully designed in VHDL. 

Synthesis and Implementation tool 

The design is implemented using Xilinx ISE 6.1 SP3 and synthesized with XST.
