It is described in synthesizable VHDL. LEON has a dual license model: Another objective was to be able to manufacture in a Single event upset SEU tolerant sensitive semiconductor process.

To maintain correct operation in the presence of SEUs, extensive error detection and error handling functions were needed. The goals have been to detect and tolerate one error in any register without software intervention, and to suppress effects from Single Event Transient SET errors in combinational logic. This section and the subsequent subsections focus on the LEON processors as soft IP cores and summarise the main features of each processor version and the infrastructure with which the processor is packaged, referred to as a LEON distribution.

While the LEON2 -FT design can be extended and re-used in other designs, its structure does not emphasise re-using parts of the design as building blocks or enable designers to easily incorporate new IP cores in the design.

Later processors in the LEON series are used in a wide range of designs and are therefore not as tightly coupled with a standard set of peripherals. Flip-flops are protected by triple modular redundancy and all internal and external memories are protected by EDAC or parity bits.

The model is highly configurable, and particularly suitable for system-on-a-chip SoC designs. LEON3 is also available under a proprietary license, allowing it to be used in proprietary applications. It has been designed for leoh3 in the harsh space environment, and includes functionality to detect and correct single event upset SEU errors in all on-chip RAM memories.
