Overview

This diagram illustrates a programming setup featuring a Flasher device by SEGGER, a BitStreamer, and an FPGA. Arrows show connections indicating data flow between the BitStreamer and the Flasher, and from the Flasher to the FPGA. The Flasher indicates readiness status for programming.

Flasher BitStreamer is SEGGER’s software tool for easy and reliable in-system programming of FPGAs and CPLDs using any Flasher production programmer.

It converts industry-standard SVF and STAPL files into ready-to-run packages that can be deployed directly to a Flasher or exported as an archive for the Flasher Deployer, within seconds and without complex setup or scripting.

With Flasher BitStreamer, SEGGER Flashers can program microcontrollers, memories, and programmable-logic devices from various vendors via the standard 4-pin JTAG interface, all using the same reliable hardware platform.

Key features

Flasher BitStreamer combines vendor-independent compatibility with an easy, command-line-driven workflow.

An icon featuring three stacked rectangular boxes labeled "X," "Y," and "Z." The background is a solid blue circle. The boxes are illustrated with lines resembling tracks on the sides, suggesting a connection or progression between them.

Broad device support

Compatible with programmable-logic devices from a wide variety of manufacturers.
Standard SVF and STAPL file formats ensure seamless integration with established FPGA toolchains.

Fast and effortless deployment

BitStreamer transforms input files into complete programming packages in seconds. These packages can be copied directly to a Flasher or deployed through Flasher Deployer for high-volume production.

A circular icon with a solid blue background features a white silhouette of a downward arrow above a triangular shape, symbolizing the concept of downloading or receiving information. The overall design conveys a sense of action and movement related to data transfer.

One tool for all Flashers

Works across the full SEGGER Flasher range, including Flasher PRO, PRO XL, Compact, Portable PLUS, and ATE 2, without additional licensing or configuration.

Use cases

Flasher BitStreamer enhances SEGGER’s production ecosystem by adding flexible programming options for programmable-logic devices. It integrates naturally into existing workflows and supports a wide range of use cases in both development and production.

Production programming of FPGA-based systems

Flasher BitStreamer enables the programming of FPGAs and CPLDs as part of standard production processes. The same Flasher infrastructure used for microcontrollers and memory devices can also configure programmable logic, simplifying setup and reducing equipment needs.

Unified system programming

Many embedded designs combine microcontrollers, external memories, and programmable logic. Flasher BitStreamer enables programming of all components with one tool: the Flasher, ensuring consistent workflows and minimizing changeover between devices or setups.

Integration into automated test systems

Thanks to command-line control and support for production-ready packages, Flasher BitStreamer can be used in automated test equipment (ATE) and other fully automated environments. It fits seamlessly into processes that require device configuration and testing in a single step.

How Flasher BitStreamer works

Flasher BitStreamer processes FPGA and CPLD programming files and prepares them for execution on SEGGER Flasher units. The generated package can be transferred to a single device or distributed to multiple Flashers for automated production.

Programming with Flasher BitStreamer simply requires an SVF or STAPL file as input and returns a package that can run directly on a Flasher.

Additional features

An abstract graphic featuring a white sinusoidal wave on a dark blue background, representing data or sound patterns. The wave has both solid and dashed lines, creating a dynamic visual effect against a backdrop of blurred dots and grid lines, suggesting a digital or technological theme.

Configurable JTAG settings

Users can select suitable JTAG frequencies to achieve optimal programming speed for each device and setup.

Two speech bubbles are centered against a dark blue background with flowing lines and dots, symbolizing communication and conversation. The design emphasizes connectivity and dialogue.

Robust diagnostic feedback

Flasher BitStreamer provides detailed progress and diagnostic output during compilation and programming.
Clear status messages and error reporting make it easy to verify operation and ensure reliable results in both testing and production.

A simple white icon depicts a downward arrow above a box, symbolizing downloading or transferring files. The background features a dark, textured design, enhancing the focus on the download icon.

Lightweight installation

BitStreamer is delivered as a single executable for 64-bit Windows. It requires no additional setup or dependencies besides the Flasher Software and Documentation pack, allowing quick installation and easy deployment across teams.

Compatibility

Flasher BitStreamer supports programming of all devices for which STAPL or SVF files are available.

Verified manufacturers:

Intel / Altera
AMD / Xilinx
Microchip / Microsemi / Actel
Lattice Semiconductor
GOWIN Semiconductor

Other programmable-logic devices that support JTAG-based SVF or STAPL programming are also compatible.

System requirements

Using Flasher BitStreamer with a SEGGER Flasher requires Microsoft Windows 10 or later (x64 or Arm).

Licensing

As with all SEGGER software, Flasher BitStreamer is provided under a perpetual license.
There are no recurring costs, maintenance fees, or per-device charges.
A company-wide license enables programming of all supported devices across all SEGGER Flasher models.

FAQ

Which Flasher models support the Flasher BitStreamer?

The Flasher BitStreamer and the projects it creates are compatible with all Flasher models (PRO, PRO XL, Compact, Portable PLUS) with hardware version 5.0 or later.
Always make sure to use the latest firmware and software.

Do I need to buy the Flasher BitStreamer for each Flasher I want to use for FPGA programming?

No. A single purchase allows company-wide use of the Flasher BitStreamer on all Flashers without limitations.

What devices are supported?

The Flasher BitStreamer has been tested with devices from Xilinx/AMD, Altera/Intel, Actel/Microsemi/Microchip, Lattice Semiconductor, and GOWIN Semiconductor.
Any FPGA from any manufacturer is supported.

How fast is FPGA programming with a Flasher?

Compilation typically takes only a fraction of a second.
