CAN Stack: A Software Solution for In-vehicle Network Communication
Our Business Engagement Model: What are the Value Adds?
Our CAN stack (ISO-11898) is a Ready-to-integrate and Production Grade communication stack. This software solution is ideal for passenger vehicle applications.
We offer this CAN stack under a one-time licensing fee model. This engagement model has proved to be a great value-add for our customers across US, India, China and Europe.
The following are some of the benefits of our One-Time Licensing Fee Model:
- You get access to the source code of the CAN Stack.
- You can become the owner of the IP rights.
- By owning the IP rights, your organization can deploy this CAN stack in multiple production programs.

FAQs About CAN Stack Solution
Ans. The layered technology architecture of our CAN stack solution is as followed:
- Low-level drivers (CAN, MCU, EEP, Timer)
- CAN Stack (CAN NM and CAN IF)
- ISO TP Layer (ISO15765)
- UDS stack
- Application Layer
Also included are:
- Bootloader Application Layer
- UDS Based Bootloader Software
Ans. CAN Stack driver is the only part of the stack that is dependent on the hardware platform. Rest of the software layers, like CAN IF and CAN NM are hardware agnostic.
It implies that the CAN driver will need to be developed based on the microcontroller used in the project.
Our automotive team has expertise of developing device drivers for all major MCU families including Renesas, Fujitsu, TI and others.
Ans. Our experience spans across several automotive ECUs, that have been powered by our CAN stack. A few of the ECUs for which we have successfully deployed CAN stack are
- Seating control ECU,
- Engine Control Unit and
- HVAC systems
Ans. Yes. Our service level agreement for CAN Stack clearly documents the fact that we will provide all the necessary configuration and integration services, along with CAN stack license.
Tool-level integration for low-level drivers as well as application level, will also be a part of our SLA.
Ans. We follow a well-defined test-plan for Our CAN software solution. We use standard tools for the following testing procedures:
- Unit level Testing
- Functional Testing
- Data Link Layer Compliance testing using vector tools
Ans. Depending on the size of the CAN Matrix file, we use manual method or an automation tool for conversion from DBC file to configuration file code.
Our proprietary PC based auto-code generator tool, is capable of generating configuration files instantly as compared to manual method that would take 2-3 weeks.
As a customer, you have the freedom to choose between the manual method and the tool-based method.
Ans. Yes, by the virtue of its design, the CAN stack solution is modular in nature. Our coding guidelines ensure that no global variables are exchanged between different source files.
Each functionality is invoked using an API. The modular nature also makes our stack lightweight in size.
Ans. We provide both HLDD and LLDD documents, along with the stack. This helps you to implement any necessary changes in the stack (in the future), with the support of your in-house team.
In addition, we will also provide documents like Functional Test Plan & Report as well as MISRA compliance Report.
