Course Description

Learn how to achieve design closure more efficiently and productively by using the three pillars of design closure (functional closure, timing closure, and power closure). Also learn how to solve functional behavior, timing, and power simultaneously to achieve faster time-to-market results.

The emphasis of this course is on:

  • Defining what design closure is and describing the three pillars of design closure (functional closure, timing closure, and power closure)
  • Using recommended coding techniques
  • Creating a test bench and running simulation for functional verification
  • Applying initial design checks and reviewing timing summary and methodology reports for a design
  • Using baselining to verify that a design meets timing goals and applying the guidelines described in the baselining process
  • Performing quality of results (QoR) assessments at different stages to improve the QoR score
  • Implementing Intelligent Design Runs (IDR) to automate analysis and timing closure for complex designs
  • Reviewing the importance of power closure and device selection
  • Estimating power consumption by using the Vivado® Design Suite Power Report utility and performing power optimization on a design
  • Identifying Versal® ACAP power and thermal solutions
  • Utilizing architecture features to improve a design's power consumption
