Questa Sim2025.2
Questa Sim 2025.2 Overview Questa Sim is a flagship electronic design automation (EDA) tool from Siemens EDA, renowned as the gold standard for mixed-language simulation and verification of complex ASIC, SoC, and FPGA designs. It supports Verilog, SystemVerilog, VHDL, and SystemC, enabling high-performance simulation, debugging, and coverage analysis. With aggressive optimization algorithms, it delivers up to 10x faster RTL simulation speeds compared to traditional tools, while maintaining a unified database for seamless debug and coverage across multi-core environments. As of October 13, 2025, Questa Sim has evolved significantly with the launch of Questa One Sim in June 2025, which serves as the next-generation foundation for Questa-based simulation. This update addresses the escalating complexities of 3D-ICs, chiplet architectures, and software-defined systems...
