Case Study: Allegro MicroSystems achieves faster anti‑lock braking system sensor development with MathWorks

Allegro MicroSystems Reduces Anti-Lock Braking System Sensor Development Time

Allegro MicroSystems, a leader in Hall‑effect sensors for automotive applications, needed to accelerate development of next‑generation ABS sensors and quickly identify and eliminate algorithm and design flaws while simulating complex driving scenarios. To meet an aggressive schedule and reduce reliance on slow transistor‑level circuit simulation, Allegro evaluated and adopted MathWorks tools, in particular Simulink and Simscape Electrical, for Model‑Based Design.

Using MathWorks’ Simulink and Simscape Electrical, Allegro implemented mixed‑mode electrical and logical models to validate algorithms and simulate real‑world targets before IC implementation. The MathWorks solution ran far faster than their IC tool, letting three engineers model eight sensors in six months, cut development of a final model to four weeks versus about four months for transistor‑level work, shorten time‑to‑market, reduce algorithm risk, and enable tests to be developed prior to manufacturing.
