Mixed-signal simulation platform speeds SoC design verification

New Products |
By Rich Pell


The new Symphony Pro mixed-signal verification solution extends the capabilities of Siemens’ proven Symphony platform to support new and advanced Accellera standardized verification methodologies with a comprehensive and intuitive visual debug cockpit, resulting in productivity improvements of up to 10X compared to legacy solutions. The platform is designed to address the strong demand for greater analog and mixed-signal content in next-generation SoCs being driven by next-generation automotive, imaging, IoT, 5G, computing and storage applications.

Mixed-signal circuits are increasingly ubiquitous – whether it is integrating the analog signal chain with the digital-front end (DFE) in 5G massive-MIMO radios, digital RF-sampling data converters in radar systems, image sensors combining analog pixel read-out circuits with digital image signal processing or feeding datacenter computing resources with ever more data using advanced mixed-signal circuits to deliver PAM4 signaling. For these and other highly advanced applications, mixed-signal circuits enable lower power, area, and cost while delivering ever-improving performance figures.

Increased application of digital control, digital calibration, and digital signal processing techniques in modern mixed-signal chip architectures is driving a paradigm shift in mixed-signal verification methodologies toward more digital-centric approaches, says the company. The Symphony Pro platform – built on the company’s Symphony and Questa Visualizer platforms – extends the rapid deployment of industry-standard Universal Verification Methodology (UVM) and Unified Power Format (UPF) driven low-power techniques into the mixed signal domain by offering fast simulation performance in a unified environment for exceptional throughput and capacity.

Modern mixed-signal SoCs integrate analog circuits with logic gates operating at very high clock speeds. This high frequency bi-directional signal flow at the boundary of analog and digital pushes the limit of manual debug methodologies impacting the overall time-to-results. Symphony Pro Visualizer MS environment is offered as providing a seamless debug experience across the entire mixed-signal design hierarchy with comprehensive analysis, automation, and ease-of-use for increased productivity.

“Our customers are rapidly advancing the state-of-the-art in mixed-signal SoC design across a wide range of applications, and in the process, they are driving the requirements for new innovations in the EDA tools required to design, verify, and validate these chips,” says Ravi Subramanian, senior vice president of IC Verification at Siemens Digital Industries Software. “We are excited to deliver Symphony Pro, which combines our proven AFS, Questa and Visualizer technologies, to our customers, enabling the potential for them to realize key competitive advantages with a unified mixed-signal verification solution.”
