Formal Verification of Floating-Point Hardware with Assertion-Based VIP  (Regular Session)

Wednesday, February 28  |  3:00–4:30 PM  |  Oak

Speaker: Sasa Stamenkovic, OneSpin Solutions
Authors: Sasa Stamenkovic, Sven Beyer, and Sergio Marchese (OneSpin); Ravi Ram, Adam Elkins, and Adnan Pratama (Xilinx)

Hardware for integer or fixed-point arithmetic is relatively simple to design, at least at the register-transfer level. If the range of values and precision that can be represented with these formats is not sufficient for the target application, floating-point hardware might be required. Unfortunately, floating-point units are complex to design, and notoriously challenging to verify. Since the famous 1994 Intel Pentium bug, many companies have investigated and successfully applied formal methods to this task. However, solutions often rely on a mix of the following: hard-to-use formal tools; highly specialized engineering skills; availability of a suitable executable model of the hardware; significant, design-specific engineering effort. In this paper, we present an alternative floating-point hardware verification approach based on a reusable, IEEE 754 compliant SystemVerilog arithmetic library. While not addressing all verification challenges, this method enables engineers to setup a formal testbench and uncover deep corner case bugs with minimal effort. Results from industrial applications are reported.

 

Using Mutation Coverage for Advanced Bug Hunting (Workshop)

Thursday, March 1  |  2:00–3:30 PM  |  Sierra

Speakers: Muhammad Haque Khan and Vladislav Palfy, OneSpin Solutions
Organizer: Tom Anderson, OneSpin Solutions

Modern verification methodologies incorporate multiple coverage solutions. These range from functional to structural coverage, leverage various coverage models and operate using varied technologies in both the simulation and formal process. The main purpose of these coverage solutions is to establish a signoff metric that indicates when enough verification has been performed. However, as coverage approaches have evolved, new use models have emerged for these tools that increases their value in the verification process. The ability of these tools to provide guidance to areas insufficiently tested, or uncover buggy scenarios is still being explored, to great effect. Mutation coverage is a relatively new technique pioneered by formal and simulation providers.

The workshop agenda will consist of:

  • Introduction to mutation coverage techniques
  • Mutation coverage with formal – it’s not so tough!
  • Sign-off with mutation coverage
  • Overview of bug hunting techniques with formal
  • Bug hunting using mutation coverage
  • Bug hunting on a practical design example
  • Overview of potential improvements using this technique.
