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 acquired 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/DCconverters
  • LED drivers, stepper motor controllers
  • EMI / EMC challenges resolving

Digital design

The embedded systems we build may utilize various state-of-the-art microcontrollers based on ARM architecture, TI DSPs, system-on-modules, and in case of small footprint applications still (!) 8-bit MCUs. We have experience with

  • STM32, NXP LPC, PIC32, TI MSP430
  • 8-bit AVR, 8051 microcontrollers
  • Engicam, Raspberry Pi, BeagleBone modules

When performance requirements make it indispensable, we implement proper accelerators in programmable logic and we have broad experience in integrating variety of “standard” subsystems like:

  • SDRAM modules, Fast Page Mode DRAMs
  • Divers Flash memories including SD cards
  • high speed serial interfaces like PCI-e, USB 3.0, Ethernet 1G or HDMI and wireless interfaces various displays and touch screens

FPGA development

Our experience includes developing and prototyping the 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 that we support include:

  • Xilinx® Vivado and ISE, MATLAB® HDL Coder
  • use of High- Level Synthesis in prototyping and implementing complex algorithms in hardware
  • implementation of DSP algorithms
  • digital beam forming networks DC and AC stepper motor controllers
  • interface controllers and chip infrastructure elements
  • implementation of systems on a programmable chip – So(P)C with MicroBlaze, SecretBlaze, PicoBlaze soft-coresand ZYNQ SoCs and MPSoCs

PCB Layout

Evatronix creates complex multi-layer PCBs as part of its turn-key product design services as well as implements PCB layouts based on a circuit schematic provided by the customer.

We realize PCBs for many applications, using advanced technologies when necessary, e.g.:

  • high-speed serial interfaces (like USB 3.0 or PCI-e) and
  • wireless interfaces containing layout for RF front end,
  • designed in accordance with EMC & high-speed design
  • rules
  • PCBs for power supplies and industrial sensors and LED
  • lighting,
  • HDI boards with micro, buried and blind vias,
  • Flex and Rigid-Flex bards

Our experience ranges from Altium Designer, Pulsonix to Mentor Graphics Expedition. Additional services may also include:

  • engineering consultancy including optimization of existing
  • projects
  • signal integrity analysis
  • reverse engineering of old designs lacking proper
  • documentation
  • generating a technical documentation for manufacturing
  • processes
  • PCBs panelization

Mechanical engineering

After customer acceptance of the enclosure study created by industrial designer, Evatronix engineers perform development of the 3D CAD model and later the 2D documentation of the product, that includes:

  • system topology optimization (weight)
  • manufacturing costs reduction
  • requirements check (e.g. durability and aesthetics)
  • usage of diverse technologies in development of mechanical elements of the system
  • computer analyses (e.g. FEM, Dynamic Motion, CFD), if required
  • specification for the controllers of step engines and other actuators passed to electronic hardware design team, if required
  • 2D and 3D manufacturing documentation (blueprints, BOMs)
