Synopsys PrimeSim 2026.03: GPU-Accelerated Circuit Simulation Platform

PrimeSim 2026.03 is the latest release of Synopsys' unified circuit simulation solution, delivering hybrid analog-mixed signal (AMS) verification with GPU acceleration and performance-optimized simulation technologies for next-generation chip design .

Key New Features in 2026.03

GPU-Accelerated Simulation (PrimeSim SPICE)

The 2026.03 release delivers a 3.5x speedup in circuit-level simulation by running PrimeSim SPICE on NVIDIA Blackwell GPUs compared to CPU-only instances . This heterogeneous compute acceleration on GPU/CPU provides significantly faster runtime while maintaining sign-off accuracy for analog, RF, and mixed-signal applications . Key features include:

• Support for high-frequency noise analysis and efficient S-parameter handling

• Advanced analysis for periodic and non-periodic time-domain and frequency-domain applications

• Seamless integration with AWS GPU resources, enabling design teams to focus on innovation rather than infrastructure management

PrimeSim HT (Hybrid Technology)

PrimeSim HT accelerates SPICE simulations by leveraging Liberty timing libraries without compromising accuracy . It introduces H-models that convert Liberty data into input-output tables, allowing digital and custom circuits to be simulated faster while maintaining SPICE-level accuracy .
