This is a comprehensive FPGA HDL reference design repository from Analog Devices, providing reusable IP cores and complete project templates for interfacing ADI data converters (ADCs/DACs), RF transceivers, and mixed-signal devices with Xilinx, Intel, and Lattice FPGAs. The architecture is modular: a library of parameterized AXI peripherals (e.g., axi_dmac, axi_clkgen, axi_pwm_gen), JESD204B/C link layer cores, SPI engine framework, I3C controller, and utility modules (clock-domain crossing, data packing, FIFOs) are assembled via Tcl-based block designs and Make-driven build scripts into carrier-specific reference designs. The repository is actively maintained with CI checks, extensive documentation (Sphinx, register maps, timing constraints), and testbenches for key blocks. It is not a software application or data research repository; it is a hardware design framework for FPGA-based acquisition and generation systems.

Scopy is a cross-platform Qt/C++ desktop application for signal analysis and instrument control, developed by Analog Devices. It provides a software oscilloscope, spectrum analyzer, signal generator, logic analyzer, data logger, and many other test-and-measurement tools. The application communicates with Analog Devices hardware (M2K, AD936x, ADRV9009, etc.) via the IIO (Industrial I/O) framework and libiio, and integrates GNU Radio for real-time signal processing pipelines. Scopy features a modular plugin architecture where each hardware target or instrument is a separate plugin package, loaded dynamically at runtime. The core framework provides reusable GUI widgets (plotting, menus, docking), an IIO attribute abstraction layer (iio-widgets), an asynchronous command queue for device operations, and a JavaScript scripting API for automation and testing. The codebase is large and well-structured, with extensive CI/CD for Linux, macOS, Windows, Android, and ARM platforms, but contains some legacy code and mixed API styles that indicate moderate technical drift.
