Design the signal chain.Deploy it to silicon.
Apexia Fabric is a visual RF and radar system design tool for AMD RFSoC platforms. Compose signal chains in a node-graph editor, watch sample rates and spectra propagate live, probe any point with virtual scopes — then hand the design to real hardware through the CASPER toolflow.
Actual application — a distributed three-board coherent array with White Rabbit timing, gain budget and data rates computed live.
01
Design
A node-graph editor with 42 block types across RF, DSP, radar, clocking, and I/O. Sample rates, data types, and center frequencies propagate live through the graph — type-checked ports catch impossible chains before you build them.
02
Simulate
Probe any edge with virtual scopes: spectrum, time, constellation, waterfall, range-Doppler heatmap, ambiguity surface, and beamformer views. The whole app runs in simulation with no hardware attached.
03
Deploy
Export Vivado TCL and casperfpga Python for the CASPER toolflow, connect live to real boards, configure RF data converters at runtime, and walk multi-tile synchronization with the built-in MTS wizard.
Radar-native, not radar-flavored
Twenty radar DSP blocks, eight waveform presets from long-range search to C-UAS drone detection, and seven complete example designs — the same processing vocabulary as our IP cores, in a tool you can explore before any hardware exists.
Hardware truth built in
Boards aren't icons — they're models. Converter counts, sample-rate limits, port and clocking configuration come from YAML board definitions, so the design that validates in Fabric is one the silicon can actually run.
Download Apexia Fabric 0.3.0 (Beta)
Windows 10/11
Installer (.exe) · x64
SmartScreen may warn — click More info → Run anyway.

Verify your download: every release ships a SHA256SUMS file — sha256sum -c SHA256SUMS (Linux), shasum -a 256 -c (macOS), or CertUtil -hashfile <file> SHA256 (Windows).
Hardware: simulation works out of the box with nothing attached. Live capture with an ADALM-Pluto needs libiio; BladeRF and LimeSDR live capture ship in a later beta — code generation for all three radios works today.
The software layer of ApexSDR
Every ApexSDR unit ships with Fabric — the same graph you simulate today is the instrument you deploy when the hardware arrives.
