Accelerating FPGA-based processor design with new design environment & IP ecosystem

03 June 2020


Lattice Propel provides RISC-V support and a robust IP portfolio to enable development of processor-based systems in minutes. Lattice is the first supplier of SRAM & Flash-based FPGAs to provide access to RISC-V technology in a simple drag-and-drop system builder environment.

Lattice Semiconductor, specialist in low power, programmable logic, has announced Lattice Propel™, its new software solution designed to accelerate development of unique applications based on low power, small form factor Lattice FPGAs.

The design environment will empower developers of any skill level to quickly and easily design Lattice FPGA-based applications, by enabling the easy assembly of components from a robust IP library that includes a RISC-V processor core and numerous peripherals. The Propel design environment automates application development for developers serving the communications, computing, industrial, automotive and consumer markets.

In order to leverage the parallel processing capabilities of FPGAs in more complex systems, first-time FPGA developers want application design solutions that are flexible, easy-to-use, and integrate all design software and IP required to develop emerging applications with a minimum learning curve. Lattice Propel’s correct-by-construction development tools automate much of the design process to simplify overall system development. Propel combines system hardware and software design into one tool framework, so software developers can begin creating system software before hardware is available and get products to market faster.

Lattice is providing a robust design environment supporting open standards like RISC-V to enable customers to take advantage of a powerful processor IP ecosystem without getting locked into proprietary technologies and standards,” said Gianluca Mariani, Technical Manager, Lattice Semiconductor. “When combined with the reprogrammability of FPGAs, the Lattice Propel environment makes it simple to upgrade existing hardware and software to support emerging technology trends and industry standards, such as Platform Firmware Resiliency. With the release of Lattice Propel, we’ve begun executing against our bold new roadmap for small form factor, low power embedded solutions.

The release of our Propel design environment is another example of Lattice’s ongoing investment in providing developers with complete software solutions that simplify and accelerate development of low power, Lattice FPGA-based applications,” said Roger Do, Senior Product Line Manager, Lattice Semiconductor. “For novice FPGA developers, the Lattice Propel GUI simplifies the design process by enabling them to drag-and-drop IP blocks from the Lattice IP library into their designs; the tool then automates the design layout to incorporate the new IP. For veteran developers, Propel also supports script-level editing for more granular design optimisation or to quickly update existing designs to port them to future Lattice FPGA-powered systems.


Key components of the Lattice Propel design environment include:

•    Lattice Propel Builder – a resource-rich system IP integration environment, supported by a complete set of GUI and command line tools. Lattice Propel Builder provides customers with access to a robust, regularly updated IP server that allows developers to implement new IP on Lattice FPGA-based designs in a matter of minutes. As of this announcement, the server currently offers eight processor and peripheral IP cores, including a RISC-V RV32I compliant processor core. Lattice is the first supplier of SRAM and Flash-based FPGAs to provide access to RISC-V technology in a simple drag-and-drop system builder environment. To simplify the connection and management of IP in more complex systems, all IP cores available through Lattice Propel Builder are compatible with the AMBA on-chip interconnect specification.

•    Lattice Propel SDK – to further accelerate designs implemented in the Propel design environment, the Lattice Propel SDK enables software development to begin before final system hardware is available. The Propel SDK includes industry-standard software development tools, software libraries and development board support packages, so developers can quickly and easily build, compile, analyse and debug their application software.

The Lattice Propel design environment is available to Lattice customers now. For more information, including demonstrations of how Lattice Propel can take an application design from concept to “Hello World” in less than ten minutes, please visit:

Lattice will host a webinar titled “Build Processor-based Systems in Minutes with Lattice Propel Design Environment” on June 23 at 10am PDT (6pm BST for UK). The webinar will highlight how easy it is to build, compile, analyse and debug application systems using Lattice Propel. To register, please visit:
