VHDL Logical Synthesis and Simulation for Xilinx™ FPGA design


5 days - 35 hours


  • Understand the architecture of a Series-7 FPGA
  • Understand the multiple possibilities offered by the VHDL language and understand the concepts of logic synthesis
  • Know the writing styles and their impact on the quality of the synthesis results
  • Know the performance that can be expected from Xilinx FPGAs and the implementation constraints
  • Handle development tools and implementation reports
  • Understand the multiple simulation possibilities offered by the VHDL language and build efficient testbenches


  • This training is intended to electronic engineers who already have a good knowledge in designing digital electronic circuits, who are willing to acquire a strong designing methodology, and to take the best of VHDL language and the associated synthesis and simulation tools for designing Xilinx FPGA.
