FPGA Design & Implementation

Custom RTL design, verification, and synthesis targeting Xilinx and Intel FPGAs. From concept through production-ready firmware.

RFSoC

SDR & RFSoC Systems

Software-defined radio architectures built on AMD/Xilinx RFSoC platforms. Multi-channel, wideband digital receivers and transmitters.

DSP

DSP Algorithm Development

Fixed-point algorithm design, spectral analysis, adaptive filtering, and modulation/demodulation chains optimized for real-time hardware.

Architecture

System Architecture

End-to-end signal chain architecture covering ADC/DAC selection, clocking strategy, data transport, and host-side integration.

High-Speed

High-Speed Interface Design

JESD204B/C, PCIe, Aurora, and Ethernet-based data movers. Proven experience with multi-gigabit serial links on FPGA platforms.

V&V

Verification & Validation

Comprehensive testbench development, hardware-in-the-loop testing, and bit-accurate simulation to ensure first-pass silicon success.

Engineering
Philosophy

High-performance signal processing demands more than clever algorithms. It requires disciplined engineering practices at every layer of the design.

01

Deterministic Latency

Every processing pipeline is designed with hard real-time constraints. Cycle-accurate timing from input to output.

02

Resource-Optimal Design

Architectures balance throughput, power, and area to meet your exact system requirements without wasting FPGA fabric.

03

Simulation-First Methodology

Bit-accurate behavioral models precede any RTL. Algorithmic performance validated before a single line of HDL.

04

Production-Grade Deliverables

Full documentation, constrained timing closure reports, and regression test suites ready for your team.
