Full-Lifecycle FPGA Engineering

SIL3 operates a structured FPGA design flow from requirements capture in ARPTool through to verified bitstream delivery. All designs target AMD/Xilinx devices and are authored to the SIL3 VHDL Coding Standard (QQP0030), with independent verification using ModelSIM and CoCoTB Python test automation. Our 179-core LVHD IP library provides proven, reusable building blocks for rapid system integration.

170+ VHDL IP Library

SIL3 maintains an in-house library of 170+ production-proven LVHD IP cores, packaged for direct integration into Vivado block designs. Each core is independently verified through ModelSIM simulation and CoCoTB test automation before being released to production projects.

Motor Control & Drives

BLDC (ESC, FOC), stepper drivers, H-bridge, PWM generation and capture. Real-time current sensing for closed-loop motor systems.

Video & Imaging Pipeline

CSI-2 RX camera capture, Bayer demosaic, colour space conversion, frame buffer management, video resize, and RGB2DVI output.

Sensor Interfaces

High-resolution ADCs (24-bit+), BiSS and AMT encoder interfaces, IMU data paths, and resolver decode for precision measurement.

DSP & Signal Processing

FFT, complex multiply, waveform generation, and sample buffering. Pipeline-ready AXI Stream interfaces for high-throughput data paths.

Networking & Communications

Gigabit Ethernet (GbE), CAN, UART, QSPI flash, and Aurora serial links. AXI Ethernet with DMA and scatter-gather support.

Timing & Synchronisation

RTC, IEEE 1588 PTP, performance timers, interrupt aggregation, and clock domain crossing infrastructure.

Vivado Design Flow & Verification

Every FPGA design is managed end-to-end in Vivado 2024.2 using block design methodology. IP cores are independently packaged, peer-reviewed, and validated before integration. Requirements are captured in ARPTool with complete bidirectional traceability.

Vivado 2024.2
