PCB Design :

Printed-circuit boards (PCBs) are at the heart of the modern electronic packaging and a part of almost every electronics product. With increasing complexity of modern electronic circuits, the demand for specialists in PCB design technologies is growing, but remains a rarely available breed of professionals.

All the high-speed and critical signals and power supply are analyzed using Hyperlynx Signal integrity and Hyperlynx Power Integrity respectively. RF designs are analyzed using the ADS tool, thus ensuring efficiency and reliability of the engineered designs. We have successfully designed and tested S-Band Transmitter/Receiver modules, Torque meter for Rotary Wing helicopter, Radio Altimeter subsystem etc..

Our PCB team is thoroughly trained and experienced in designing High-density Rugged Digital, Analog, RF, IF and Power supply Boards using MIL Grade standards. We use developmental tools that enable collaborative development of PCBs. Design features include

  • Signal Integrity analysis
  • Differential Signals length matching
  • High Speed signals Signal Integrity Analysis
  • Clock Routing - Signal Integrity Analysis

Firmware Design Services:

RDS provides complete FPGA development life cycle support, from specification to final tested product. We cover multiple application areas including test bench design, and, system validation or technology migration..

Our design team is trained on the latest architecture and optimization techniques across FPGAs/CPLDs. Our professionals are experienced in High Speed Digital Design using Virtex 7, Kintex series Xilinx FPGAs, Altera and Actel FPGAs. Capabilities include experience in RTL (Verilog, VHDL, SystemVerilog).

We employ a wide umbrella of programming skills, interface designs, algorithm development and architecture optimization. We deliver with professional ease because of many person-years of experience in design tools and devices such as Xilinx, ISE/VIVADO, Microsemi, Altera, MATLAB, Simulink and System Generator etc.

We also have experts to ensure that the product can be satisfactorily realized using simulating tools prior to irreversible stages. Simulation tools include Xilinx ISIM, Modelsim, etc. We can get involved in the design and development process at any stage including:

  • Requirement & Feasibility Study
  • Device Selection
  • Architecture Definition
  • RTL Coding
  • Functional simulation
  • Verification & Validation
  • Synthesis and resource Optimization
  • Floor-planning & Timing Closure
  • Testing

Firmware Design Services:

RDS has a large engineering design group carrying out design of electronic packaging and complex mechanical parts specific to the application domain. The nature of the products designed can be broadly categorized as below:

  • Rugged military equipment On-ground & Airborne
  • Automatic test equipment
  • Radar systems
  • EW sub-systems
  • Gimbals

In general, we offer product design for Air & Conduction-cooled enclosures, large rack systems & consoles, and, gimbals & precision parts. All systems and products are designed and developed to conform to required international and military standards.

Our expertise includes thermal analysis, often with the need to meet MIL-STD specification; Thermal Design for Electronic Cooling Covers, Conduction Heat Transfer, Analysis and Flow analysis for identifying Hot Spots in PCB. We also employ Finite Element Analysis (FEA) to simulate field conditions prior to actualization. Our design offering encompasses 2D and 3D modeling from concept to completion.

We are able to create jigs and fixtures where required, for manufacturing and testing mechanical assembly, to specified weight ratios. Static and dynamic shock mounts are optimized to meet actual conditions, and for exceptional use cases as well. EMI, EMC compatibility is ensured with accurate calculations for selecting standard Honey Comb designs.
