Silexica GmbH was a German software company that specialized in providing advanced C/C++ programming and analysis tools designed to optimize software for multicore processor architectures. Their flagship product, SLX FPGA, and the broader SLX Tool Suite, helped developers partition and parallelize code, particularly for embedded systems in automotive, wireless communications, and aerospace/defense industries. Silexica was founded in 2014 with the mission to enable efficient software development for the multicore era. In June 2021, Silexica was acquired by Xilinx, Inc. Subsequently, Xilinx was acquired by Advanced Micro Devices, Inc. (AMD) in February 2022. Silexica's technologies and team were integrated into Xilinx (now AMD) to enhance their software development tools and high-level synthesis (HLS) capabilities.
Served as the primary center for research and development, corporate operations, engineering, and management for Silexica's global activities prior to its acquisition.
Located in Mediapark, a modern business and cultural complex in Cologne, offering contemporary office spaces and amenities suitable for a technology company.
Silexica fostered an innovative and engineering-driven work culture, emphasizing collaboration, technical excellence, and addressing complex software challenges for multicore systems. Employees often highlighted the dynamic startup environment.
The Cologne headquarters was pivotal for Silexica's growth, product development (including the SLX Tool Suite), and establishing its presence in the European tech ecosystem.
Prior to its acquisition, Silexica operated with a global outlook, headquartered in Germany and maintaining regional offices in the USA (Silicon Valley) and Japan (Tokyo). This presence allowed them to serve a worldwide customer base in sectors like automotive, wireless communications, and aerospace. Their tools and expertise were distributed internationally, supported by direct sales and technical teams as well as partnerships. Post-acquisition, these global functions and customer support have been integrated into AMD's (formerly Xilinx's) larger global operational structure.
