Electronic System Design

SimLab helps bring Altair’s simulation-driven design philosophy to the electronics industry, inspiring innovation while ensuring timing, performance, reliability, and compliance targets are met. A direct interface to common ECAD formats allows EDA users to confidently identify and correct potential design issues earlier in development. Thermal analyses can be easily performed without requiring advanced CFD knowledge. Automate structural stress, vibration, and drop test performance assessments with robust and repeatable workflows for fast, accurate, and consistent analysis, even for occasional users. SimLab even models fiber orientation during the injection molding process of plastic enclosures and manages structural solver coupling.

Enhanced Chip and 3D IC Reliability

Altair's ESD solution represents a shift in the design and optimization of integrated circuits (ICs) and heterogeneous packages, employing a singular, integrated process centered around a 3D digital twin that expands collaboration and accelerates design. This approach is pivotal in solving complex systems' interrelated power and thermal challenges. What-if floor planning studies for various chiplet configurations in SimLab empower multidisciplinary teams to better understand power profiles and cooling efficiency and identify potential thermal hotspots and weak points early in the design phase.

Additionally, SimLab improves the reliability of 3D IC designs and packages by ensuring resilience against warpage under compressive stresses, a common issue that can create significant reliability concerns in densely packed chiplet configurations. With SimLab’s proven, integrated approach, chip manufacturers can navigate the complexities of 3D IC design with greater confidence and precision – ultimately leading to more reliable and cost-effective electronic systems.

Thermal and Flow Analysis

Reduce the complexity of transient heat transfer, steady state and transient flow, plus injection molding simulations with SimLab. Quickly understand the performance of a heat sink, convection heating system, or the cooling of an axle housing with fast meshing, material property assignment, and defined boundary conditions. Move from CAD to the simulation of turbulent flow problem with surface mesh, volume mesh, and boundary automated layer generation. The injection molding application simplifies the pre- and post-processing of advanced manufacturing simulations.

Multiphysics Modeling

While SimLab accelerates the simulation of structural, thermal flow, and electromagnetic physics, its workflows also enable the fast analysis of thermal and mechanical physics using a single model including a one-step transient thermal stress analysis. These advanced simulations allow engineers to understand how parts behave under real world conditions in environments requiring linear or nonlinear steady-state, linear transient analysis, or contact-based thermal analysis.

Structural Analysis and Optimization

With application specific workflows for drop test, fatigue, and structural optimization, SimLab simplifies complex analysis problems. Import an existing CAD geometry, retain parametrization, and automatically mesh to quickly experiment with design variants for an increased understanding of linear static, non-linear static, normal modes, modal frequency response, or small displacement performance. Alternatively, be guided through the definition of a design space, responses, constraints, and an optimization objective to use Altair® OptiStruct®to generate a lightweight and structurally efficient design proposal.

Sound and Simulation: Designing a Smart Speaker

Speaker design and analysis, especially for a more complex product, system, or component, often requires building multiple simulation models. The loudspeaker development process involves multi-physics and multiple sources in parallel, to multiple simulation runs for prototyping, testing, and validation. This results in separate models for nonlinear analysis of strength, thermal analysis and stiffness, noise, vibration, and acoustics. Even though each model isn’t always built from scratch, typically the use of different solvers for each attribute will require that models need to be converted from one solver format to another. This practice is not only time consuming but frequently error prone resulting in an inefficient use of engineering time.
