  • Comprehend the various possibilities offered by VHDL language
  • Be able to read and test VHDL components
  • Understand the logical synthesis notions
  • Understand the crucial issue of implementing Finite State Machines (FSMs) in hardware
  • Organizing the code developing package and libraries
  • Reusing components
  • Learning how to write efficient testbenches for simulation
  • Knowing the different writing style and their impact on the quality of synthesis results
  • Checking Timings
  • How to structure and write large and complex VHDL structured verification environments
  • The OSVVM and UVVM VHDL verification methodologies
Course environment
  • Theoretical course
    • Course material (in English) in PDF and print format
    • Course dispensed using the Teams video-conferencing system
    • The trainer answers trainees’ questions during the training and provides technical and pedagogical assistance
  • Practical activities
    • Practical activities represent from 40% to 50% of course duration
    • They allow to validate or deepen the knowledge obtained during the theoretical course
    • One PC per pair of trainees for the practical activities
    • Xilinx Vivado IDE
    • Code examples, exercises and solutions
  • At the start of each session, a period is devoted to an interaction between the trainees and the trainer to ensure the course fit their expectations and adapt it if needed
