With leading expertise in high-tech product development, embedded systems and industrial IT & automation, Prevas contributes by providing innovative solutions and services that create growth

Services

Product Design & Development

Today, many market-leading companies outsource parts of their research and development activities. The reasons for this vary; increased focus on core activities, resource issues (time, competence, facilities) or improved control over the commercial risks related to R&D projects.

 

Among smaller companies, it’s relatively common to have only a few R&D projects running at the same time, and sometimes only one project every other year. In these cases, it is difficult to maintain quality, cost control and have a high productivity. In these situations, it makes a lot of sense to partner up with someone like Prevas, who is constantly running complex projects at all times.

We offer a complete infrastructure for delivering complex R&D projects:

 

  • Development tools for software, electronics, and 3D-CAD
  • PDM-Link server for product data management
  • Electronics lab for development, prototyping, and testing
  • Mechanical engineering workshop for prototyping
  • Customer-specific labs for development and testing
  • Electro-Magnetic Compatibility (EMC) lab for compliance testing
  • A modern IT infrastructure for running distributed R&D projects
  • Certified according to ISO 9001:2008 and ISO 13485:2012 (Sweden/Sundbyberg)
  • MDD/IVDD/QSR-compliant development model

System Development

Delivering robust and effective system solutions require experienced design and implementation teams. Prevas has senior project managers, system designers and system engineers, who are experienced from numerous solution deliveries.

Our professionals are eager to help you during for example pre-studies in selecting the best technical solutions, regardless if you are seeking standard solutions or tailor-made solutions for very specific applications. They are also experts on most standard platforms in the manufacturing domain, and they can help you to pick the best implementation strategy for a particular system.

 

Prevas has specialists in many technology areas, and they work closely with our platform partners from ABB, GE, Infor, Invensys, Microsoft, Novotek, Oracle, Quintiq, Siemens etc.

Software Design and Development

Software design and development is far too complex a profession to be described in a limited number of key words, but one thing is certain: the better the competence, the better the result. Prevas has a long track-record of delivering software solutions to industrial customers. We understand the benefit of delivering structured code that is well documented and well tested.

For our customers that need on-site consultants helping out in their projects, we have developed our own competence database that enables us to get the best competence match to the customer requirements. Our competence database also provides our on-site consultants with a tool to find support from all of Prevas’ collective knowledge.

When required, our consultants can bring our own workstations and development tools to work on-site. This is especially appreciated by our customers with smaller R&D capacity or when highly specialized tools are required.

 

We can provide expert consultants with competence in: c#, c++, ADA, VHDL, UML, Linux, Android, Agile development, and many more.

Electronics Design and Hardware Design

Hardware design not only requires technical competence but also the ability to execute development projects in a short period of time and at high quality. Prevas has high experience in advanced electronic design from many successful projects. Modern electronic design also requires knowledge of regulatory requirements regarding high speed data, EMC, RoHS, and safety. Prevas has its own labs and design tools, so we can develop products from specification to finished product.

For our customers that need on-site consultants helping out in their projects, we have developed our own competence database that enables us to get the best competence match to the customer requirements. Our competence database also provides our on-site consultants with a tool to find support from all of Prevas’ collective knowledge.

When required, our consultants can bring our own workstations and development tools to work on-site. This is especially appreciated by our customers with smaller R&D capacity or when highly specialized tools are required.

 

We can provide expert consultants with competence in: ARM, DSP, FPGA, x86, high speed data, Hyperlynx, PCB layout, analog design, RF design, digital design, 60601-1, EMC, RoHS, LVD, and many more.

High-speed PCB Design Solutions

Due to the high speeds of many electronic designs in modern technologies, the physical characteristics of the design-implementation (PCBs, packages, interconnects, etc.) contribute to the behavior of the circuits just as much as the parts of the electrical design that are included in the schematic. Increasingly fast edge rates in today’s ICs cause undesirable high-speed effects, even in PCB designs running at low operating frequencies. As driver ICs switch faster, there is a risk of signal degradation – such as ringing, glitching, crosstalk, and timing problems.

 

All of this, as well as emission and immunity, are some of the factors that must be considered during the design work, thus mitigating problems with eg signal integrity (SI) and electromagnetic compatibility (EMC).

 

The electrical characteristics are directly influenced by board-level and system-level features such as PCB material, size and stack-up, placement of components, decoupling and bypassing, routing topology, signal line terminations, motherboard-daughterboard configuration, connectors, grounding, etc.

Prevas has experience from many high-speed projects and assignments and has a deep knowledge in the design requirements and conditions. To make a good, reliable, high-speed PCB design, it is often necessary to use a qualified simulation tool like Hyperlynx. Prevas can assist our customers to guide and help throughout the design process and do the needed simulations.
