Cortus

France

Cortus is an established ASIC/SoC Design company with a very large selection of their own proprietary IP including processors (Cortus proprietary ISA and RISC-V ISA) and many other Analog/RF, Mixed-Signal, Digital and Security (HW & SW) IP.

 

We believe that the success of a solution starts very early in the system architecture phase, where the hardware/software split or digital/analog split decisions are made. Our extensive experience of prototyping and virtual prototyping has been the key to success for a number of our customers.

 

One of the benefits of working with Cortus is our extensive in-house IP portfolio. This provides many advantages, our engineers are very familiar with it, the IP integrates well, and it is cost effective both in power and silicon area.

 

Our IP is generally licensed as part of a design services contract.
