Silicon IP Licensing

We use an open-source business model based on dual licensing. This model allows to provide commercial licenses for a fee, while at the same time offering the source code under open source licenses. The advantages of the dual licensing are:

‍

• Free access for the academic research community
• Free evaluation possibilities for companies
• Large user base gives sizeable and quick feedback

‍

If you obtain the IP-cores under the open source license, and use this IP in a commercial product, you are required to release your modifications and additions under the same license conditions. The commercial license relieves you from disclosing your modifications and additions and includes full documentation, maintenance, warranty and test benches. Our commercial IP core licensing options are designed to provide flexibility and scalability to meet your project needs. We offer two distinct license types tailored to different use cases.

GRLIB distributions

‍

• The GPL distribution is the open-source version of the IP library, and is subject to the terms and conditions of the GNU General Public License. The distribution is regularly updated and made available here. Note: the fault-tolerant options are not supported in this tier.
• The COM distribution is the commercial version of the IP library and may target both FPGAs or ASICs. Note that fault-tolerant options are not supported in this tier.
• The FT-FPGA distribution is the fault-tolerant version of the IP library targeting FPGAs. It includes all features present in the COM release plus fault-tolerant functionality (like ECC protection for memories) and support for additional FPGA families.
• The FT distribution is the fault-tolerant version of the IP library targeting ASICs. It includes all features present in the FT-FPGA release plus additional cores and functionality for ASIC development, as well as support for ASIC technologies. An ASIC license also allows for prototyping
  on FPGAs without additional costs.

License types

‍

Single product license

• This license covers one FPGA or ASIC design for a single product, which could be defined as a custom IC, a board, or a complete system that includes an FPGA or ASIC.
• The design can be used to tape-out one ASIC, with unlimited production of the ASIC parts, or to program an unlimited number of FPGA parts
• Any modifications or alterations to the design are considered new designs and will require a separate license.

‍

Single project license‍

• This license allows unlimited use of the IP core within a single project at one company site. A project is defined as a specific electronic unit or instrument, such as those used in spacecraft.

‍

Additional information for both license types

‍

• Royalties: Applicable to all processors and major IP cores, with royalties charged only for flight models

• Maintenance: Both license includes one year of maintenance. A maintenance period signifies receiving upgrades and feature additions done within the licensed IP cores.
  

• Optional Add-ons:
  • Technical Support: One year of technical support can be purchased separately.
  • Extended Maintenance and Support: Available annually for an additional fee
