Synopsys announced availability of its first Multiphysics Fusion solutions on June 17, one year after completing its $35 billion acquisition of Ansys. The portfolio combines Synopsys' AI-powered EDA tools with Ansys golden signoff analysis across timing signoff, design closure, multi-die design, and analog workflows. Key solutions include Multiphysics Fusion for Timing Signoff, which delivers SPICE-accurate analysis with up to 3x faster runtimes and integrates Synopsys PrimeTime with RedHawk-SC thermal and IR analysis; Multiphysics Fusion for Multi-die Designs, which unifies Synopsys 3DIC Compiler with electromagnetic analysis for power, thermal, and EM effects; and integrated Analog and Photonic Design flows. Early validation from market leaders including Cisco, MediaTek, NVIDIA, and Samsung Foundry demonstrates measurable gains by shifting from costly overdesign to integrated, system-aware co-design.
The solutions address a structural problem: as chips reach advanced nodes and multi-die architectures, physics-related challenges—signal integrity, power integrity, thermal integrity, electromagnetic effects, and co-packaged optics—become critical constraints that previously warranted point-solution or afterthought treatment. By embedding physics directly into the digital and analog design flow, teams can iterate fewer times and optimize silicon earlier. Synopsys is also leveraging NVIDIA CUDA-X libraries (including cuDSS) to deliver GPU-accelerated physics kernels, further speeding convergence.
For chip design teams, the timing is critical: as chiplet density increases and frequencies push higher, EM and thermal cross-talk that were secondary now gate sign-off. Synopsys' integration of Ansys' multiphysics engine into the EDA stack removes the need for separate simulation sprints, reducing time-to-market. The rapid (6-8 month post-acquisition) delivery of commercially available tools signals that the Ansys deal integration is progressing, and that co-design workflows will become table-stakes for 2.5D/3D designs.
