Logic simulation apps for verification of domain-specific designs

By mixing and matching Xcelium Apps, says the company, Xcelium users can achieve up to a 10x regression throughput improvement.

“Xcelium Apps are the next step in the evolution of logic simulation performance,” says Paul Cunningham, senior vice president and general manager of the System & Verification Group at Cadence. “These apps deliver domain-specific technologies to enable the highest levels of verification performance at both the IP and full-chip level of modern SoC designs.”

The Xcelium Apps portfolio includes:

  • Machine Learning: The Xcelium Machine Learning (ML) App utilizes proprietary ML technology to reduce regression times by learning from previous regression runs and guiding the Xcelium randomization kernel to either achieve the same coverage with significantly less simulation cycles or catch more bugs around specific coverage points of interest.
  • Mixed-Signal: The Xcelium Digital Mixed-Signal (DMS) App enables native co-simulation with Cadence Spectre SPICE analog simulation, as well as advanced SystemVerilog real number model-based simulation.
  • Multi-Core: 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 (DFT) simulations.
  • Safety: The Xcelium Safety App enables serial and concurrent fault simulation, which when combined with the Cadence safety verification full flow comprised of Jasper Safety, vManager Safety, and Midas Safety Planner, enables the highest performance safety campaign execution for ISO 26262 compliance.
  • Power Playback: The Xcelium PowerPlayback App enables the 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.
  • X-Pessimism Removal: 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.

The Xcelium Apps and the Xcelium Logic Simulator are part of the company’s verification full flow, which includes Palladium Z2 emulation, Protium X2 prototyping, the Jasper Formal Verification Platform, the Helium Virtual and Hybrid Studio, the vManager Verification Management Platform, memory and interface Verification IP (VIP), and System VIP. The Cadence verification full flow is part of the Cadence Intelligent System Design strategy.
