Portfolio of Apps
Discover Apps for the Xcelium Logic Simulator
Xcelium Apps work natively with the Xcelium Logic Simulator and enable design teams to achieve the highest verification performance at both the IP and full-chip level of modern SoC designs.
The Xcelium SimAI App harnesses the power of machine learning technology. It builds models from regressions run in the Xcelium simulator, enabling the generation of new regressions with specific targets. This includes efficient soak testing of the entire design or specific areas and improved regression efficiency. The app also features cousin bug hunting, a unique capability that uses information from difficult-to-hit failures to expose cousin bugs. With these advanced machine learning techniques, SimAI offers the potential for a significant boost in productivity, promising an exciting future for our users.
The Xcelium Mixed-Signal App enables native co-simulation with Cadence Spectre SPICE analog simulation, as well as advanced SystemVerilog real number model-based simulation.
The Xcelium Multi-Core (MC) App significantly reduces runtime for long-running high activity tests by multi-threading the Xcelium kernel, such as on gate-level design for test pattern simulations.
The Xcelium Distributed Simulation Verification App enables simulation of multi-die and chiplet systems across multiple compute processes, accelerating verification bring-up while expanding beyond the resource capacity of a single simulation. The app links multiple cooperative individual Xcelium simulations running in parallel, utilizing Xcelium virtual channels to facilitate the flow of data and synchronization events. This approach provides a shift-left for early testing of the interoperability of a system of dies across on-premises or cloud servers, offering potentially unbounded compute scalability. The app brings significant performance benefits and accelerates verification productivity by leveraging existing verification infrastructure.
The Xcelium Safety App is ISO 26262 certified and enables serial and concurrent fault simulation, which when combined with Cadence’s safety verification full flow, comprising Jasper Safety, vManager Safety, and Midas Safety Planner, enables the highest performance safety campaign execution for ISO 26262 compliance.
The Xcelium PowerPlayback (PPB) App enables massively parallel Xcelium replay of waveforms captured by Palladium emulation onto a timing-annotated gate-level netlist for glitch-accurate power estimation of multi-billion gate SoC designs.
The Xcelium X-Pessimism Removal (XPR) App shortens debug time by using advanced algorithms to make the propagation of “X” values in simulation more accurate.
