Semiconductor test platform MISTRAL6

Overview
MISTRAL is the next-generation ATE platform designed to accelerate semiconductor test from development to high-volume production. Built for power, mixed-signal, automotive and digital applications, MISTRAL combines high-density instrumentation, a modular and scalable architecture, and an AI-native test development environment to simplify creation, deployment and scaling of test solutions.

Unlike traditional ATE platforms, MISTRAL provides a unified hardware and software environment across characterization, validation and production. The same instruments, DUT interface and test programs can be reused across the MISTRAL6, MISTRAL12 and MISTRAL16 systems. Open architecture allows any instrument in any slot, synchronized and concurrent testing, and integration of external instrumentation. High parallelism, high-density resources, low-cost application boards and no per-instrument software licensing reduce cost of test while lowering entry investment. Powered by Polaris (Cosmic’s AI-native Tester Operating System), MISTRAL brings intelligence into test development to shorten development cycles, simplify debug and accelerate time-to-market.

Reasons Why

• Reduce Cost of Test
• Accelerate Time-to-Market
• Complete instrument and custom portfolio
