Both Galileo and Leonardo tools support the following general and Xilinx specific features 

  • Verilog and VHDL/VITAL
  • SDF Backannotation for Timing Analysis
  • Timing Analysis
  • Schematic Viewer
  • Both tools support the following Xilinx specific optimization features
    • Unified Library
    • Complex IO mapping
    • LUT Optimization
    • XC3K, XC4K, XC4KE, XC5K, XC4KXL based technologies
    • MODGEN support for operator generation
    • User Defined State Machine Encoding
    • Carry Chain synthesis support
    • CLB packing
    • GSR inferencing
  • Features specific to Galileo 
    • Simple, non-interactive and encapsulated user interface
  • Features specific to Leonardo:
    • Support for clock, input delay, output delay, load and maxcap timing constraints
    • Full constraint based critical-path timing optimization
    • Hierarchical Database

    *Xilinx Alliance Series Design Environment 

    The Alliance Series represent Xilinx's next generation baseline technology for implementation and integration functions. This advanced technology enables digital system designers to increase design performance, leverages standards-based, high-level design methodologies, and quickly receive future software updates and device support for Xilinx FPGA and CPLD devices. 

    The Alliance Series technology provides dramatically improved design performance through advanced placement and routing algorithms, powerful "auto-interactive" design tools delivering the choice between a push-button or manually-directed design flows, and support for standards based design methodologies including EDIF, SDF, VHDL and Verilog.
