The Verdi system lets you focus on tasks that add more value to your designs, by cutting your debug time, by typically over 50%. These time savings are made possible by unique technology that:

  • Automates behavior tracing using unique behavior analysis technology
  • Extracts, isolates, and displays pertinent logic in flexible and powerful design views
  • Reveals the operation of and interaction between the design, assertions, and testbench


Complete Debug System

The Verdi automated debug system incorporates all of the technology and capabilities you would expect in a debug system. In addition, the Verdi system combines advanced debug features with support for a broad range of languages and methodologies.

Core Features

The Verdi system provides the following fundamental debug features:

  • Full-featured waveform viewer enables you to display and analyze activity over time
  • Powerful waveform comparison engine allows you to isolate differences between fast signal database (FSDB) files
  • Source code browser enables you to easily traverse between source code and hierarchy
  • Flexible schematics and block diagrams give you the ability to display logic and connectivity using familiar symbols
  • Intuitive bubble diagrams help you to reveal the operation of finite state machines

Advanced Features (Debug)

The Verdi system also includes the following advanced debug features: 

  • Automatic tracing of signal activity enables quick trace activity across many clock cycles with powerful behavior analysis technology 
  • Temporal flow views provide a combined display of time and structure to help you rapidly understand cause and-effect relationships 
  • Assertion-based debug with built-in support for assertions facilitates quick traversal from assertion failure to related design activity
  • Verdi Regression Debug Automation (RDA)
  • Verdi Intelligent Debug Acceleration (IDX)

Advanced Features (Testbench debug)

  • Full source code support for SystemVerilog Testbench (SVTB) and libraries, including Universal Verification Methodology (UVM), to ensure reusability and interoperability of testbench code
  • Specialized views that help you understand testbench code, including declaration-based hierarchy browsing and navigation, class inheritance and relationship comprehension, and tracing
  • Built-in message logging and automated UVM transaction recording capabilities, coupled with advanced visualization techniques, give you a complete picture of testbench activity in the post-simulation verification environment
  • Full-featured interactive simulation control allows you to step through complex testbench code for more detailed analysis
  • UVM aware debug views allow users to explore verification results from specific UVM aspects like resources, factory, phase and sequence
  • Transaction-level debug views are based on extended FSDB and support new transaction and relation data recording
