Approach:
Our development capabilities meet growing demand for outsourced design services coming from understaffed R&D departments of corporations, from start-ups lacking technical skills to implement their products & service ideas, from companies that miss specific skillset among their R&D teams.
Depending on these diverse customers’ needs our collaboration model may differ, but always assumes tight interaction with the customer:
- Turn-key product development or focused engineering services to detailed customer specification (e.g. FPGA, PCB layout, embedded software development)
- Fixed-price or time and material contracts
- Quick path to demonstration of user interface mock-ups and product concept visualization to enable knowledgeable changes to initial product requirements
- Optional feasibility studies in case of complex or highly innovative projects that require exploratory phase to adjust the project scope
- Project reviews and progress reports in agreed time intervals to ensure satisfying transparency of the design process
Initial Design Phase:
When our team is challenged with a new design idea brought by a customer, we proceed with high-level design and we try to disambiguate and fine tune the requirements to ensure we will meet them all and we will deliver the best user experience possible. This initial design phase may include:
- Development of a computational model of the controlled object and actuators
- Development of critical control and signal processing algorithms
- Definition of the product and system architecture
- Visualization of a physical product (shape and interface)
- Design of a graphical user interface mock up or prototype
Algorithm Development and Analysis:
Our experienced engineers help with definition of process automation, data processing or computing algorithms, especially in:
- Digital filters design
- Fast signal Convulsion algorithms (Overlap-Save) instead of a complex system of filters
- Development of hardware accelerated DSP algorithms
- FPGA designs for acceleration of computational algorithms (multiplication, division, FFT, Cosine transform Wavelet transform, image processing, etc.)
- Development of 2D and 3D filtering algorithms for critical conditions and applications
- Adaptive filtering algorithms
System Architecture Development:
Defining system architecture based on initial requirements is often a challenging task. Evatronix may develop variants of architecture and propose the best solutions. We may map the required functionality to an embedded system containing microcontrollers, DSP processors or FPGA chips. The embedded devices can be accompanied by Cloud, mobile or PC applications.
In the phase of architecture development, we utilize Model-Based Design methods, including application of high-level modelling tools like MATLAB®/Simulink®. Using our proprietary technology, we can later provide support for algorithm and architecture validation with FPGA-in-the-Loop and Hardware-in-the-Loop techniques.
Industrial Design:
Evatronix performs creative industrial design process in close collaboration with the customer to rapidly converge on ideas and ensure customer’s satisfaction from the end result. The usual steps to make this happen include:
- Development of concept based on agreed set of requirements for the product (sketch)
- 3D shape study creation (computer visualization)
- Refinement of selected variant based on shape study
Graphical User Interface Design:
To provide good user experience is one of our goals when designing and developing graphical interfaces for the embedded system. GUI design can be deployed in various hardware platforms, like: embedded or attached displays, mobile applications on smartphones, and Web applications.
Our design process of a creative solution to meet the client’s requirements may incorporate:
- Creating the look and feel design of an embedded display, a mobile app or a website
- Focusing on the end user’s experience
- Creating user interactivity features
- Designing custom graphics for the GUI
- Developing graphical mock-ups
- Enabling code implementation for a wide array of hardware targets
HARDWARE DESIGN
Mechanical Engineering:
After customer accepts the result of the shape study created by industrial designer Evatronix engineers perform development of 3D CAD model and later the 2D documentation of the product.
To optimize system topology (weight), manufacturing costs and fully meet requirements (e.g. durability and aesthetics) diverse technologies are used in development of mechanical elements of the system.
When necessary certain computer analyses (e.g. FEM, Dynamic Motion, CFD) may be performed. Specifications for the controllers of step engines and other actuators are defined to be passed to electronic hardware design team if required.
Analog and Mixed Signal Design:
Analog and mixed signal design remains an essential part of contemporary embedded systems. Evatronix has analog and mixed-signal designers among the engineering staff and collaborates with a network of top level professionals who have many years of experience in this field so that we could address the toughest design challenges. Our design capabilities include:
- Sensor interfacing & signal conditioning
- RF front-ends for diverse wireless communication standards
- Analog filters
- A/D and D/A conversion
- Miniaturized switching power supplies and DC/DC converters
- LED drivers, stepper motor controllers
- Resolving EMI / EMC challenges
Digital Design:
The embedded systems we build may utilize various state-of-the-art microcontrollers based on ARM architecture such as STM32, system-on-modules, and in case of small footprint applications still (!) 8-bit MCUs. We have experience with
- Engicam, Raspberry Pi, BeagleBone modules
- 8-bit AVR, 8051 microcontrollers
They include programmable logic, when performance requirements make it indispensable and may integrate subsystems like:
- SDRAM modules, Fast Page Mode DRAM
- High speed serial interfaces like PCI-e, USB 3.0, Ethernet 1G or HDMI and wireless interfaces
- Graphical displays (HDMI, VGA, DVI, DisplayPort)
- Serial Flash memory, EEPROM
Radio Frequency Engineering:
In many projects, especially in IoT applications, wireless communication of some kind is required and necessary. Evatronix has experience in technologies like:
- LTE, GSM/GPRS cellular communication,
- Wi-Fi, Bluetooth, BLE, Zigbee or RFID wireless interfaces
- GPS/GLONASS-based positioning
FPGA Development:
Our experience include developing and prototyping significant number of complex IP cores. The on-going development of on-chip infrastructure supporting HDL model acceleration in FPGA gives us unprecedented intimacy with Xilinx architectures. Therefore we can easily handle designs spanning from simple functional blocks (like SPI controller) to complex interfaces (like AXI bus controller) or computational modules (e.g. Digital Beam Forming for SAR system) or an entire Systems-on-Programmable-Chip. Technologies and application areas supported include:
- MicroBlaze, SecretBlaze, PicoBlaze soft-cores and ZYNQ SoC and MPSoC
- Implementation of DSP algorithms
- DC and AC stepper motor controllers
- Digital beam forming networks
