Modelsim HDL Simulation
Modelsim HDL Simulation
Modelsim HDL Simulation, now evolved into Questa One Sim, is the industry-leading functional simulation platform for ASIC, SoC, and FPGA designs. It delivers three core benefits: faster engines, faster engineers, and fewer workloads, enabling teams to complete verification tasks with significantly reduced resource demands.
Questa One Sim merges advanced verification workflow capabilities into a single environment, combining high-performance simulation with advanced debug, portable stimulus, and coverage-driven regression tools to accelerate time-to-market for complex chip designs.
Key Modelsim HDL Simulation Solutions:
- Fastest simulation engine for DFT patterns
- RTL and gate-level simulation
- ParallelSim with auto-partitioning
- VHDL constraint solver support
- Advanced X debug with patented technology
- SmartCompile for 3DIC and AI designs
- Multi-test profiler for regression analysis
- Built-in PSS engine for UVM sequences
Built-in PSS Capabilities
Portable Stimulus capability enables reusable test scenarios across multiple platforms and abstraction levels, specifying intent once to generate diverse test cases while reducing redundancy and human error.
