Course Description

This course is intended for people with little or no experience in Formal Analysis (FA) and JasperGold®. This course illustrates, in a very pragmatic way, how to code SVA properties that are efficient for Formal Analysis. Formal Analysis is a completely different paradigm to older and more widely adopted methods of verification like simulation. As such, the fundamental objectives, capabilities, limitations, setup and initialization requirements, in addition to analysis and interpretation of results, need to be well understood before we can make effective use of FA tools and specialized JasperGold Apps. Formal is capable of much more than simulation alone and can deliver optimization techniques often needed to be applied to get conclusive results within realistic timescales. These techniques are extremely difficult to discover or pick up "as one goes along" without training or expert assistance. Anyone can run an FA tool but experience is needed to get conclusive results in a realistic timeframe that are completely understood. This course is intended as a shortcut to gaining that experience. The course has 60% lectures and 40% hands-on labs.

Learning Objectives

After completing this course, you will be able to:

  • Define reusable, functionally correct SVA properties that are efficient for formal tools
  • Set up, run and analyze results from Formal Analysis having identified designs upon which formal is likely to be successful
  • Understand formal complexity issues and how to overcome them
  • Create a complete formal environment from scratch given only a DUT functional specification
  • Set up and run Superlint and X-Propagation Apps

Software Used in This Course

  • JasperGold
  • VIPCAT 11.3

  • Differentiate between what is an abstraction and what is a reduction
  • Use abstraction mechanisms to greatly reduce the time taken for a formal proof
  • Apply IVAs to choose arbitrary configurations
  • Apply Reset Value Abstractions (RVAs)
  • Apply counter abstractions

XPROP App

  • Use the XPROP App to detect, debug and fix X-propagation issues for a variety of X-sources and destinations
  • Use the –precond option to prevent real X-prop problems being masked by the waiving of false negatives

The Verification Completeness Problem

  • Review verification methodologies
  • Examine case study highlighting the verification completeness problem
  • State techniques for minimizing risk of verification holes
  • States the merits of each verification technique

Property Development Introduction

  • Overcoming the "blank page syndrome"

Interface Property Development

  • Develop black-box protocol properties
  • Enumerate a finite set of fundamental behaviors for features extracted from a verification plan
  • Enumerate a finite set of protocol categories with which common protocols are associated
  • Identify the subset of fundamental behaviors exhibited by a given protocol category
  • Use these fundamental behaviors to drive the development of the protocol properties
  • General vs. specific properties and why specific properties may be undesirable

Audience

  • Design and Verification Engineers

Prerequisites

You must have one month of experience writing properties with SVA.

Or, you must have completed the following course:

NOTE: This course is a subset of the online only course #86235 titled SVA, Formal and JasperGold Fundamentals for Designers. This course does not cover basic SVA syntax and principles.

If you do not know any SVA then it is recommended to first do the SVA sections at the beginning of the online only course SVA, Formal and JasperGold Fundamentals for Designers.
