SystemVerilog Testbench
  

OVERVIEW

In this intensive, three-day course, you will learn the key features and benefits of the SystemVerilog testbench language and its use in VCS.

This course is a hands-on workshop that reinforces the verification concepts taught in lecture through a series of labs. At the end of this class, students should have the skills required to write an object-oriented SystemVerilog testbench to verify a device under test with coverage-driven random stimulus using VCS.

Students will first learn how to develop an interface between the SystemVerilog test program and the Device Under Test (DUT). Next the workshop will explain how the intuitive object-oriented technology in SystemVerilog testbench can simplify verification problems. This course concludes with an in-depth discussion of functional coverage including a uniform, measurable definition of functionality and the SystemVerilog constructs that allow you to assess the percentage of functionality covered either dynamically or through the use of generated reports.

To reinforce the lecture and accelerate mastery of the material, each student will complete a challenging test suite for real-world, system-based design.


OBJECTIVES

At the end of this workshop the student should be able to:

  • build a SystemVerilog verification environment
  • develop a stimulus generator to create constrained random test stimulus
  • develop device driver routines to drive DUT input with stimulus from generator
  • develop device monitor routines to sample DUT output
  • develop self-check routines to verify correctness of DUT output
  • abstract DUT stimulus as data objects
  • execute device drivers, monitors and self-checking routines concurrently
  • communicate among concurrent routines using events, semaphores and mailboxes
  • develop functional coverage to measure completeness of test

AUDIENCE PROFILE

Design or Verification engineers who write SystemVerilog testbenches at the block or chip level
