Development Platform IDE

Eclipse based IDE allows the managed build using the HighTec compiler tools. The IDE includes a project wizard with pre-configured board support packages. Ready to uses examples projects can be downloaded and imported via the content manager.

ISO 26262 ASIL D Certification and QKit

HighTec offers for its compiler an ISO 26262 Tool Qualification with an ASIL D methodology certified by TÜV.

Ensures the highest safety standards for your safety-critical application while maintaining for the customer a simple and straightforward process.

The HighTec Qkit provides a collection of documents that serves as evidence that the developed application using the HighTec compiler is compliant with the safety standard ISO 26262.

For further details, visit our Qkit page.

PPU: MetaWare for AURIX Distribution

Complete MetaWare ecosystem, including optimization libraries and math functions.

The MetaWare compiler, developed by Synopsys and supported and distributed by HighTec, is based on LLVM technology, allowing for straightforward integration with HighTec's compiler solutions.

This collaboration and shared LLVM compiler technology ensure that our customers can effortlessly leverage the benefits of both compiler technologies, guaranteeing seamless interoperability.
