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.

QSPY sequence diagram generation

QSPY Sequence Diagram Generation

The QSPY host application can now generate sequence diagrams. This new feature replaces the previous support for MscGen and is no longer reliant on any such external tools. The sequence output generated by QSPY is a simple ASCII file, which
