Vivado Design Suite Advanced XDC and Static Timing Analysis for ISE Software Users

Course Description

This course will update experienced ISE® software users to utilize the Vivado® Design Suite. Learn the underlying database and static timing analysis (STA) mechanisms. Utilize Tcl for navigating the design, creating Xilinx design constraints (XDC), and creating timing reports. Learn to make appropriate timing constraints for SDR, DDR, source-synchronous, and system-synchronous interfaces for your FPGA design.

You will also learn to make path-specific, false path, and min/max timing constraints, as well as learn about timing constraint priority in the Vivado timing engine. Finally, you will learn about the scripting environment of the Vivado Design Suite and how to use the project-based scripting flow.

You will also learn the FPGA design best practices and skills to be successful using the Vivado Design Suite. This includes the necessary skills to improve design speed and reliability, including: system reset design, synchronization circuits, optimum HDL coding techniques, and timing closure techniques using the Vivado software. This course encapsulates this information with an UltraFast™ design methodology case study. The UltraFast design methodology checklist is also introduced.

Lab Descriptions

  • Lab 1: Vivado IDE Database – Explore the Vivado IDE database using Tcl commands. Use the Tcl Console to evaluate and enter IOB properties.
  • Lab 2: Introduction to Clock Constraints – Create complete XDC constraints for the clocking resources in a design. Implement the design and use the available clocking reports to verify results. Understand the first step in the Xilinx baselining recommendation.
  • Lab 3: I/O Constraints and Virtual Clocks – Create input and output constraints for a source-synchronous design by using the Timing Constraints utility. You will also generate useful timing reports to verify the timing results. Understand the second step in the baselining recommendation.
  • Lab 4: Introduction to Timing Exceptions – Use the Timing Constraints window to enter timing exceptions in the XDC format. You will also generate a useful timing report to verify the timing results. Understand the third and last step in the baselining recommendation.
  • Lab 5: Source-Synchronous I/O timing – Make I/O timing constraints for a source-synchronous, double data rate (DDR) interface. Perform a static timing analysis of the interfaces to determine the optimal clock and data relationship for maximum setup and hold-time margin. Finally, adjust the data path delay to realize the optimal timing solution.
  • Lab 6: Scripting in Vivado Design Suite Project Mode – Write Tcl commands in the project-based flow for the design process (from creating a new project through implementation).
  • Lab 7: Resets – Investigate the proper design and use of resets. Examine the impact of seeing a design built originally with asynchronous resets, having resets removed, and finally with synchronous resets only used where necessary.
  • Lab 8: Inference – Evaluate the implementation results of a design that uses asynchronous resets and infers more dedicated hardware resources when resets are selectively removed from the design. You will also learn how to infer the DSP hardware resources for other common functions required by most FPGA designs.
  • Lab 9: Timing Closure and Design Conversion – Learn how a generic processor design was optimized for the 7 series device architecture with basic design changes that impacted the dedicated hardware usage, design speed, and the device utilization.
  • Lab 10: Pipelining – Explore how pipelining can improve performance (increased clock rate and throughput) and facilitate timing closure.
