Altair SimLab 2026.0 Linux64 Tested Picture
Enhanced Chip and 3D IC Reliability
Altair’s Electronic System Design (ESD) solution simplifies and accelerates the design of integrated circuits (ICs) and 3D packages using a unified process built around a 3D digital twin. With SimLab, engineers can explore different chiplet layouts, analyze power and cooling performance, and spot thermal hotspots early in the design phase. SimLab also boosts reliability by addressing warpage issues. With integrated, proven workflows, chipmakers can design more reliable and cost-effective systems with greater confidence.
