Ashling RiscFree™ C/C++ Development Suite for SiFive RISC‑V Devices.
Ashling RiscFree™ For SiFive RISC‑V Cores
Fast RISC‑V CPU Design
Custom SoC's in weeks, not months!
Ashling provides a comprehensive tools solution for SiFive’s RISC-V based cores, including C/C++ cross-compiler support for any RISC-V ISA with custom extensions. This includes Ashling’s RiscFree™ Eclipse-based Integrated Development Environment (IDE) for RISC-V, which provides a complete, seamless environment for RISC‑V software development.
HiFive Unleashed RISC‑V development board. Featuring the Freedom U540, a Linux-capable, multi-core, RISC‑V processor. HiFive Unleashed ushers in a brand-new era for RISC‑V.
- IDE based on Eclipse with full source and project creation, editing, build and integrated debug support
- Includes automatic source-code formatting, syntax coloring and function folding
- Includes a single-shot installer that installs and automatically configures all the component tools to work “out-of-the-box”.
- Project wizards and examples allowing you to quickly create projects from scratch or use the pre-built examples
- Full compiler toolchain including an optimizing C/C++ compiler, assembler and linker including start-up code and run-time libraries. Compiler toolchains support optional user specific customisations, see our compiler and tools services for more details
- Hardware Debug (Opella-XD) and Trace probe options fully integrated into the Debugger allowing debug and easy setup, capture and display of Trace and Profiling data
- Multi-core debug support
- On-chip trace and debug analytics support
- ROM or RAM based debugging support (e.g. hardware breakpoints for flash-based support)
- Includes QEMU ISA simulator for 32 and 64-bit RISC-V cores
- High-level RISC-V Register Viewer (XML database driven)
- Integrated RTOS debug support
- Integrated Serial Terminal
- Script language for automating debugging sessions
Ashling’s Tools-as-a-Service (TaaS™) offers many benefits to SiFive users including:
- Rapid availability of a customized and optimized toolset for your device including some or all of the following: IDE, Debugger, Compiler Toolchain, Simulators, Hardware Debug and Trace Probes, Operating Systems, BSPs etc.
- Toolset feature priorities and roll-out defined by you and implemented by us
- Toolset intellectual property becomes yours (or can be placed in Escrow)
- Toolset can be made available “free-of-charge” to your customers
- Toolset development, support, maintenance and quality assurance all handled by Ashling
Ashling’s Opella-XD is a high-speed JTAG debug probe for embedded development on RISC-V cores. Opella-XD for RISC-V is the latest in a number of high speed debug probes supporting MCU, SoC, and Soft (FPGA) based designs and highlighting 30+ years of experience developing and building embedded development tools.
Features of Opella-XD for RISC-V:

- Up to 3MB/s download speeds particularly suitable for large, complex projects
- Fully powered by USB interface; no external power-supply needed
- Fine-grained adjustment of JTAG clock frequency from 1KHz to 100MHz.
- Multi-core support with full JTAG scan-chain configurability
- Detects and automatically configures for the appropriate target voltage from 0.9V to 3.6V
- Fast in-target Flash and FPGA Programming
- Support for all on-chip hardware breakpoints; unlimited number of software breakpoints
- Configurable Target-Reset and Test-Port-Reset, under full user control
- Built-in diagnostics instantly show status of Target, Debug Probe and USB link
