State Machines & Tools
for Embedded Systems

We’re on a mission to bring Quantum Leaps in quality and productivity to embedded software development. Our modern QP™ real-time embedded frameworks (RTEFs), the QM™ modeling tool, and the QTools™ collection enable event-driven architecture, finite state machines, model-based design and automatic code generation.

Embedded Software

QP real-time embedded framework (RTEF)

QP™ Real-Time Embedded Frameworks (RTEFs)

Quantum Leaps' QP/C and QP/C++ real-time embedded frameworks (RTEFs) provide lightweight, reusable software architecture based on event-driven active objects (actors) and finite state machines. Ideal for ARM Cortex-M and other 32/16-bit microcontrollers. Also integrated with Linux/POSIX.

Host-Based Tools

QM modeling tool for state machines

QM™ Model-Based Design Tool

QM™ (QP Modeler) is a freeware model-based design (MBD) and automatic code generation tool for designing software based on finite state machines (UML statecharts) and the QP™ frameworks.

QTools collection

QTools™ Collection                     

QTools™ is a collection of various open source host-based tools for working with the QP frameworks, such as tools for: software tracing, unit testing, monitoring and prototyping.
