Transitioning to new standards using model-based design


The impact of the new standards to UAV developers using model-based design is especially significant. Before describing this, an introduction to model-based design is appropriate.
Introduction to model-based design
With model-based design, UAV engineers develop and simulate system models comprised of hardware and software using block diagrams and state charts, as shown in Figures 1 and 2. They then automatically generate, deploy, and verify code on their Embedded Systems. With textual computation languages and block diagram model tools, one can generate code in C, C++, Verilog, and VHDL languages, enabling implementation on MCU, DSP[], FPGA[], and ASIC hardware. This lets system, software, and hardware engineers collaborate using the same tools and environment to develop, implement, and verify systems. Given their auto-nomous nature, UAV systems heavily employ closed-loop controls, making system modeling and closed-loop simulation, as shown in Figures 1 and 2, a natural fit.
Testing actual UAV systems via ground-controlled flight tests is expensive. A better way is to test early in the design process using desktop simulation and lab test benches. With model-based design, verification starts as soon as models are created and simulated for the first time. Tests cases based on high-level requirements formalize simulation testing. A common verification workflow is to reuse the simulation tests throughout model-based design as the model transitions from system model to software model to source code to executable object code using code generators and cross-compilers.
An in-the-loop testing strategy is often used as itemized below and summarized in Table 2:
1. Simulation test cases are derived and run on the model using Model-In-the-Loop (MIL) testing.
2. Source code is verified by compiling and executing it on a host computer using Software-In-the-Loop (SIL) testing.
3. Executable object code is verified by cross-compiling and executing it on the embedded processor or an instruction set simulator using Processor-In-the-Loop (PIL) testing.
4. Hardware implementation is verified by synthesizing HDL and executing it on an FPGA using FPGA-In-the-Loop (FIL) testing.

5. The embedded system is verified and validated using the original plant model using Hardware-In-the-Loop (HIL) testing.
A requirements-based test approach with test reuse for models and code is explicitly described in ARP4754A, DO-178C, and DO-331, the model-based design supplement to DO-178C.

Almost half of Industrial automation sales in Asia

A recent report by IHS has shown that in 2012, capital expenditure on industrial automation equipment in Asia reached a total of $76.6bn, representing 46% of global investments in the sector.
Despite this established and rising trend, selling automation computers equipment in Asia remains a clear business opportunity and one where many European providers are lagging behind.

In order to help businesses better understand how to take advantage of the current climate and increase their industrial automation sales in Asia, particularly China, the CC-Link Partner Association (CLPA) is hosting a seminar entitled ‘Gateway to China’. The event will take place on 24th September at the Mitsubishi Electric Europe Tokyo Conference Suite in Hatfield.

In light of the sensitive current economic climate, many Asian companies are taking a more careful approach to investment – they are becoming more demanding towards their suppliers and making more enquiries before purchasing. Furthermore, according to IHS’ research, several Chinese manufacturers are currently developing products which are in direct competition with the ones provided by Western suppliers of industrial automation. These are only a few of the obstacles facing European vendors who want to penetrate the Asian market to change the way they do business.


Flexibility and the ability to respond to very specific demands are becoming essential factors when dealing with the Asian market. Being able to offer technologies and solutions which are compatible with the needs of Asian clients is no longer an option, it’s a must.

Register Protection under main event


Register Protection
There may be modules in the design whose configuration should not change during the run phase of the chip, and in doing so may affect the proper operation of the system. One can disable access to these registers during run phase, or make such registers as write-once.

Redundant critical on-chip modules like processor, ISO, DMA controller, internal clock generator, and communications peripherals can improve reliability should a primary hardware module become non-functional while the vehicle is running. Such a system can have in-built error detection mechanisms and on-the-fly switching to redundant hardware to mitigate threats to passenger safety.
But this kind of redundant hardware architecture comes with the penalty of increased area and higher power management in silicon. Area penalties can be minimized by intelligent selection of which functions need to be duplicated in silicon. Power can be minimized by adopting power and clock gating in the redundant modules. Some  in-vehicle computers can be implemented in lock-step of each other, where primary and redundant modules process the same input. Mismatch in the output of the lock-step modules indicates a defect in either of the modules. The system can switch itself off or take appropriate safety measures to avoid any real-time failure. Redundant hardware should be placed quite far in silicon from the primary embedded systems to avoid tampering of both modules together.

IT Technology for industrial applications


It is the author’s opinion that integration of the controls networking  and the IT network is inevitable. It became inevitable the moment the controls industry chose to use Ethernet as the medium with which to communicate data. The controls industry may choose to be dragged kicking and screaming into the modern automation  era, or it can gracefully embrace the change. Embracing means the controls industry would be able to leverage the myriad rich, existing technologies that have been proven foolproof in the IT world. To be dragged kicking and screaming into the modern communications era would do a terrible injustice to those who have worked diligently to bring it about. This could quite possibly add an entirely new facet to the fieldbus wars, which I hope have not been forgotten.
With that said, the controls world is going to be moving with an industry that has a definite consumer bias, with product development and release cycles of six months or less. In an industry where the average life expectancy of an automotive production line is eight years, it is impossible to expect the networking in an industrial setting to keep up with modern IT standards. Therefore, we turn our attention to the technologies that have existed the longest, with the most open standards and the very best support. These are the protocols we wish to use and keep, and this article highlights and explains some of these technologies.

Memory protection is crucial for your embedded system


Memory protection to prevent applications from interfering with one another  solutions accelerators that ensure deterministic, low-latency responses for real-time guests.

The ability to assign I/O to guest OSs for unimpeded, high-performance access Several Alliance members provide RTOS and hypervisor products that support the 4th generation Intel Core processors. For example, fanless embedded systems TenAsys eVM for Windows is a real-time hypervisor that uses Intel VT to enable RTOSs and other guest OSs to run along with Microsoft Windows. TenAsys also offers the INtime RTOS family, which can run as a stand-alone RTOS or alongside Microsoft Windows as shown in Figure 3. Both products enable users to partition a multicore platform to run mixed fanless embedded systems, making better use of the processor’s advanced features to provide highly integrated  solutions. (Microsoft and TenAsys are both Associate members of the Alliance.)

In search for best techno solutions


While many pneumatic actuators have remained unchanged, except for the addition of smart positioners, there have been some new innovations in pneumatic actuation.
A number of piston and rotary actuators have been creeping into power plants, which primarily have used diaphragm actuators on control valves. Pneumatic actuators equipped with smart positioners now functionally compete with electric actuators in terms of fail-in-position operation on loss of signal at significantly less cost ofembedded systems.

They work in harsh environments, and they get little or no recognition. But their impact on power plant efficiency can be significant. Valves and actuators are critical in almost every aspect of single board computer
