2. Next-Generation RTL Generation

The new RTL engine delivers faster and more compact hardware structures, producing 25% smaller area utilization and higher clock speeds. With improved pipeline balancing, Catapult 2025 provides superior throughput for compute-intensive applications such as AI accelerators, image processing, and 5G communication systems.

3. Extended Language Support

Catapult HLS 2025 adds comprehensive support for C++20 and SystemC 2.3.4, enabling designers to leverage modern language constructs for greater expressiveness and maintainability. The enhanced compiler now supports lambda expressions, constexpr, and modular compilation, ensuring full compatibility with today’s advanced development workflows.

4. Seamless EDA Tool Integration

Integration with Siemens EDA’s Questa Advanced Verification, Calibre physical verification, and Aprisa place-and-route tools has been strengthened. This ensures a consistent and efficient end-to-end flow—from algorithm development and synthesis to verification and physical implementation.

5. Low-Power and Energy-Aware Design

With tighter integration of PowerPro technology, Catapult HLS 2025 automatically applies clock gating, power gating, and dynamic voltage scaling to reduce total power consumption without sacrificing performance. These new features are particularly valuable for mobile, IoT, and automotive applications.

6. Redesigned Graphical User Interface (GUI)

The updated GUI includes new interactive dashboards, enhanced visualization for performance metrics, and intuitive reports for area and timing analysis. Engineers can now compare multiple synthesis runs visually, simplifying architectural decision-making.

7. Improved Verification Flow

Catapult HLS 2025 introduces advanced SystemC-to-RTL co-simulation and enhanced formal equivalence checking, ensuring that every generated RTL block matches the high-level design specification accurately.
