  • The goal of the course is to study the components of digital design & advanced concepts in synthesis process
  • To understand the importance of technology, libraries, design constraints, design rules
  • To understand the usefulness of reports with respect to design on Area, Timing & Power

Learning Outcomes:

  • Ability to set constraints, Validate the results and analyze the reports
  • Ability to synthesize the design based on Area and Timing priority
  • Ability to perform critical path synthesis
  • Ability to perform timing analysis on the synthesized netlist
  • Ability to verify the functional equivalence of the synthesized netlist Vs RTL
