This site provides information about how simulation and virtual platforms can provide significant improvements to the approaches used for the development of embedded software. It discusses Continuous Integration for Embedded Systems and provides background material on the approaches used. It also has many pages of details on many virtual platforms that are used for the development of embedded software.
Nagra, part of the Kudelski group, a global leader in digital security and convergent media solutions for the delivery of digital and interactive content stated: “At NAGRA, we have adopted the Imperas virtual platform-based software development and test tools for our application and firmware teams. The simulator performance, and the tools for software analysis, have added significant value to our daily Agile Continuous Integration (CI) methodology. Our view is that software simulation is mandatory to reach metrics required for high quality secured products.”
From the O’Reilly Smart Jenkins book…
“A good CI infrastructure can streamline the development process right through to deployment, help detect and fix bugs faster, provide a project dashboard for developers and non-developers, and ultimately, help teams deliver more business value to the end user.
Every professional development team, no matter how small, should be practising CI.”
Adopting a modern approach to developing embedded software
Modern methodologies for developing embedded software focus around much automation for developing, testing, and deployment. In the desktop software segment an approach called Continuous Integration is at the centre.
Continuous Integration (CI) (https://en.wikipedia.org/wiki/Continuous_integration) is where a build server monitors code check ins to a source code repository and initiates automatic build and unit testing ensuring that whenever code is checked in it is integrated and initial testing is performed.
For embedded software this is a challenge as the software needs to run on a specific piece of embedded hardware often with a non-x86 cpu and with often several non-PC components. To test embedded software requires either the actual embedded hardware or a prototype of it. In fact to really adopt real automation for Continuous Integration you need many copies of the hardware so that many tests and users can operate in parallel.
This is the biggest challenge and the reason why so many users of Continuous Integration of Embedded Software are turning to simulation and virtual platforms to be at the centre of their test approach.
If you want to use a Continuous Integration methodology for embedded software development simulation and virtual platforms become essential.
By developing and testing embedded software using simulation and virtual platforms the adoption of a Continuous Integration approach becomes straightforward and beneficial.
Using a Continuous Integration server such as Jenkins with Virtual Platform simulation for embedded software development
To manage the building and unit testing that is at the heart of any continuous integration approach requires a build server.
Jenkins (https://jenkins.io/) is one of the leading open source solutions for desk top software. It was originally developed for Java program development but now works well with C/C++ and Make as needed for embedded systems.
Imperas has been using Continuous Integration with a build server and test automation system for over 5 years.
Imperas uses Jenkins internally and has customers developing embedded software using Jenkins and test automation using Imperas virtual platform simulation products.

Fastest Simulation of ARM and MIPS virtual platforms
Industry Standard Debug and IDE
Each virtual platform supports standard debugging interfaces and can be connected using RSP to GDB, either standalone or within an Eclipse IDE environment. The models also connect to the advanced multi-core debugger available as part of the Imperas Advanced Multicore Software Development Kit product.
