Edit SysML v2 models with Eclipse SysON, an open-source and web-based MBSE modeling tool.
An implementation of the OMG’s specification SysML v2: language concepts, REST API, and textual interoperability format
SysON was presented during the Vendor Roadmaps and Implementation Status session of the MBSE Workshop held as part of the INCOSE International Workshop 2025, in Seville, Spain, on February 1, 2025.
We're thrilled to share that we've already made significant progress toward our goals!
As demonstrated in the quick demo, SysON is up and running—packed with powerful features and designed with a strong focus on user experience.
The project is on the right track and is already generating considerable interest.

SysML was created in 2005 as a standard for model-based systems engineering (MBSE) to elevate the role of models as primary tools for communication and documentation.
With system complexity continuing to escalate exponentially, and Digital Engineering emerging as a pivotal pillar to address an ever-challenging world, SysML 2.0 has been specified as the next-generation systems modeling language to improve precision, expressiveness, and usability.
SysON’s objective is to provide System Engineers with super easy access to this new standard, at minimal cost and great ease of use, with the guarantee of interoperability with other open-source MBSE tools notably Capella and Papyrus.
This will be achieved through three means: the support of the SysML 2.0 standard, the use of state-of-the-art web technologies, and an open-source approach.
SysON aims at facilitating systems engineers to seamlessly work with both SysML v2 and Capella. Exchange of architecture models with Capella will be natively supported in SysON.
Beyond the primary unlocking service, the website also offered a reset option ( huaweicodecalculator.com/reset-hash/ ) for certain routers, designed to restore factory settings when the administrator password was forgotten. As an online tool, it required an internet connection for its calculations.
: Many "code calculator" sites have become ad-heavy or defunct. Users should exercise caution, as entering an IMEI into an unverified site can sometimes be a privacy risk. Notable Alternatives
| Data | Where to find it | Example | |------|------------------|---------| | (15 digits) | Dial *#06# on your phone | 864512034567890 | | Model number | Phone settings → About phone | ALE-L21 , P20 Lite | | S/N (Serial Number) | On the box or in Settings → About → Status | ABCDEF123456789 | | Product ID | Dial *#*#1357946#*#* (old Huawei devices) | 8–10 digits | huaweicodecalculatorcom
In an official context, a manufacturer like Huawei generates a unique unlock code for a device by using its unique 15-digit IMEI (International Mobile Equipment Identity) number. This is calculated using a secret algorithm. The websites and tools claiming to be "code calculators" typically operate by either employing a leaked or reverse-engineered version of this algorithm, or by acting as a front-end to a paid database that provides these codes for a fee.
The platform serves as a specialized database and algorithm calculator. It processes a device's unique International Mobile Equipment Identity (IMEI) number to generate specific unlock codes. Core Functions: Used for older Huawei modem models. Beyond the primary unlocking service, the website also
are specialized software utilities or web-based services designed to generate network unlocking keys (NCK) and firmware flash codes for Huawei mobile phones, USB dongles, and portable MiFi routers using the device's unique International Mobile Equipment Identity (IMEI) number. Historically popularised by platforms like huaweicodecalculator.com and developer tools such as DC-Unlocker, these algorithms bypass carrier restrictions, allowing consumers to switch telecom networks freely. Understanding the Technology Behind Huawei Unlocking
To understand why this calculator works, you have to understand how Huawei devices are locked. Users should exercise caution, as entering an IMEI
Dial *#06# on your phone or check the label under the battery or on the back of your router.
On the webpage, you will see a single input field. Enter the code exactly as shown (case-sensitive in some versions). Click the "Calculate" or "Check" button.
Type huaweicodecalculatorcom directly into your browser’s address bar. Avoid clicking on suspicious third-party links. Ensure the connection is secure (look for the padlock icon in the address bar).
Obeo provides expertise to help you integrate SysON within your organization, and tailor or extend it to fit your needs.

Obeo is also preparing a secure cloud-based offering to provide SysON as a fully hosted SaaS solution, enabling users to access and use it without any deployment on their machines or servers.
Stay tuned…
Alongside the open source development of SysON, Obeo is working on advanced commercial features to support cutting-edge deployments for large-scale and/or mission-critical projects.
Stay tuned…The project team works in an iterative mode to deliver a new version every 8 weeks.
The first release of SysON, version 2023.12, was launched in December 2023 by Obeo and CEA List.
The SysON roadmap takes into account user feedback and needs identified as part of an Open Innovation approach.
For the next months, our main goals include:
In 2025, we will intensify our collaborations with industrial partners to elevate SysON to the forefront of SysML V2 modeling tool excellence
and prepare it for professional, operational, and large-scale deployment.
