Features and Benefits:

  • Language Support: Questa supports popular HDL (Hardware Description Language) standards, including VHDL, Verilog, and SystemVerilog. Designers can use their preferred HDL language to describe and simulate digital designs.
  • Simulation and Debugging: The suite provides advanced simulation and debugging capabilities. Engineers can perform both RTL (Register Transfer Level) and gate-level simulations and use the interactive debugging environment to trace signals, view waveforms, inspect internal registers, and identify and resolve design issues efficiently.
  • Functional Coverage: Questa supports functional coverage, which allows designers to measure how much of the design’s functionality has been exercised during simulation. Functional coverage analysis helps ensure comprehensive verification and identifies untested parts of the design.
  • Assertion-Based Verification (ABV): The suite includes support for assertion-based verification using SystemVerilog Assertions (SVA). Designers can specify properties that the design should satisfy, enabling formal verification and the detection of potential bugs.
  • UVM (Universal Verification Methodology) Support: Questa is fully compatible with UVM, a widely adopted verification methodology in the industry. It provides built-in support for UVM, enabling efficient and scalable testbench development and verification.
  • Coverage Driven Verification: Questa facilitates coverage-driven verification, where verification engineers set coverage goals and continuously track the progress of verification against those goals. This approach ensures comprehensive verification and maximizes the effectiveness of testbenches.
  • Verification Planning: The suite offers capabilities for verification planning and management. Engineers can create detailed verification plans, track progress, and manage testbenches, coverage, and results.
  • Formal Verification: Questa includes formal verification engines that allow designers to perform exhaustive checks on specific design properties, ensuring that the design complies with specified requirements.
  • Low Power Verification: The suite provides support for low power verification techniques, enabling engineers to verify the correct operation of power management features and optimize power consumption in their designs.
  • AMS (Analog-Mixed Signal) Verification: Questa also offers features for AMS verification, allowing designers to simulate and verify the interaction between digital and analog components in mixed-signal designs.
