Questa One Sim
Questa One Sim is the evolution of the functional simulator. It combines various verification flow aspects, boosting performance and productivity by leveraging faster engines. This enables faster engineers who use fewer workloads to finish verification tasks.
Why Questa One Sim?
Questa One Sim brings cornerstone Questa simulation technologies into a platform that is geared towards solving challenges faced by semiconductor companies designing the next generation of SoC's, ASIC's and FPGAs. Questa One Sim enables faster engines, faster engineers and fewer workloads.
Faster engines
- Fastest simulation engine in the industry for DFT pattern simulations
- New optimizations for faster RTL and gate-level simulations
- ParallelSim with smart auto-partitioning capability for even faster performance
Faster engineers
- Faster X debug capability with patented X-debugging feature
- New SmartCompile capability reduces simulation turnaround time for 3DIC, AI-accelerator designs
- Enhanced debug environment with many new advanced debugging capabilities
Fewer workloads
- Root cause performance bottlenecks on regressions using all new multi-test profiler
- Generate complex UVM sequences faster with built-in PSS engine
- Expand VHDL verification to the next level with VHDL constraint solver support
Built-in PSS capabilities
The built-in Portable Stimulus capability revolutionizes verification by enabling reusable test scenarios across multiple platforms and abstraction levels. It lets you specify intent once and generate diverse test cases, reducing redundancy and human error. From IP to system level, adapts seamlessly to different verification environments while maximizing productivity throughout the entire verification flow.
Enhanced debugging capabilities to improve productivity
The integrated simulation and debugging engine gives you a new and improved interface for a more efficient verification flow. New dedicated debug windows for X-debug, constraints debug and protocol-aware debug enable a faster way to analyze complex verification environments. The ever-popular profiler can now profile across multiple tests to give you a regression-wide analysis of simulation hotspots.
CDC metastability injection in RTL simulation
In concert with Questa CDC, Questa One Sim can now dynamically inject CDC metastability into RTL functional simulation to verify the DUT is tolerant of random delays caused by metastability. This capability as part of the simulator dramatically increases the number of simulations that can be run with CDC metastability injection enabled.
