Electronic Circuits and Semiconductors
Barr Group is in the business of designing reliable and secure computers and our electrical engineering experts are intimately familiar with the design of electrical circuits such as:
- Analog and digital electronics, including antennas
- Nonvolatile memories (NAND/NOR Flash) and caches
- Light-Emitting Diodes (LEDs) and other displays
- Printed Circuit Boards (PCBs)
- Field Programmable Gate Arrays (FPGAs) and CPLDs
- Application-Specific Integrated Circuits (ASICs)
- System-on-a-Chip (Soc) and multi-chip modules (MCM)
- Wafer manufacturing processes and IC packaging
- Microprocessor/microcontroller/CPU design
- Digital Signal Processor (DSP) design and filtering
- Graphics Processing Unit (GPU) design
- Microcode and instruction set architecture design
- High-level language compiler development
- Multiprocessing and parallel programming
Barr Group's electronics expert witnesses are familiar with all of the tools used to design and test circuits and semiconductors, from hardware description languages like Verilog and VHDL to simulation tools like SPICE/HSPICE. We are as equally skilled with electronic design automation platforms as with schematic capture, register transfer logic, and assembly language code.

Case Study: Satellite TV Piracy
In its legal fight against signal pirates, DirecTV retained a team of Barr Group's to engage in thorough electronic circuit reverse engineering and device testing of over one hundred suspected piracy products. Barr Group experts testified that the majority of the accused products were designed for use in satellite TV piracy in several dozen cases that went to trial.
