The Symphony Pro platform extends the robust mixed-signal verification capabilities of Siemens’ proven Symphony platform.

To address the design verification challenges of the world’s most complex mixed-signal system-on-chips (SoCs), Siemens Digital Industries Software has launched the new Symphony Pro platform. This next-generation solution extends the robust mixed-signal verification capabilities of Siemens’ proven Symphony platform to support new and advanced Accellera standards-based verification methodologies with a powerful, comprehensive, and intuitive visual debugging cockpit, making results in up to 10x productivity improvements over existing solutions. .

Next-generation automotive, imaging, IoT, 5G, computing, and storage applications are driving strong demand for greater analog and mixed-signal content in next-generation SoCs. Mixed-signal circuits are becoming more ubiquitous, whether 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 reading circuits with digital image signal processing or feeding data center computing resources with ever more data using advanced mixed-signal circuits to provide PAM4 signaling. For these and other highly advanced applications, mixed-signal circuits reduce power, area, and cost while delivering ever-improving performance.

“Functional verification of mixed signals is increasingly vital to our sophisticated designs for the imaging and automotive industries. We participated in the Early Access Program for Symphony Pro and saw significant productivity gains due to the advanced debugging capabilities and seamless support for multi-layer sandwich configurations in Symphony Pro,” said Stéphane Vivien, Senior CAD Manager , Imaging Division, STMicroelectronics. “We look forward to using Symphony Pro as an approval solution for current and future mixed-signal verification projects.”

The 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 . Siemens’ new Symphony Pro platform, based on the proven performance of Siemens’ Symphony and Questa Visualizer platforms, extends the rapid deployment of Universal Verification Methodology (UVM) and format-driven low-power techniques from unified power (UPF) in the mixed signal. domain by delivering fast simulation performance in a unified environment for exceptional throughput and capacity.

Modern mixed-signal SoCs incorporate analog circuitry with logic gates operating at very high clock speeds. This high-frequency bi-directional signal flow at the analog/digital boundary pushes the boundaries of manual debugging methodologies that impact overall time to results. The Symphony Pro Visualizer MS environment provides a seamless debugging experience across the entire mixed-signal design hierarchy with full analysis, automation, and ease of use for increased productivity.

“Our high-performance, power-efficient chips designed for the IoT are analog-intensive and mixed-signal in nature. To ensure high quality, we have extended our digital verification methodology to enable efficient regression of our mixed-signal designs,” said Jayanth Shreedhara, senior CAD manager at Silicon Labs. “Symphony Pro Visualizer mixed-signal technology has accelerated the debug time of our digital UVM test suites on top, improving our verification productivity from days to hours and significantly improving our coverage closure.

“Our customers are rapidly advancing the state of the art in mixed-signal SoC design across a wide range of applications, and in doing so, they are driving the demands for new innovations in EDA tools needed to design, verify , and validate those chips,” said Ravi Subramanian, senior vice president of integrated circuit verification at Siemens Digital Industries Software. “We are excited to offer our customers Symphony Pro, which combines our proven AFS, Questa and Visualizer technologies , enabling them to realize key competitive advantages with a unified mixed-signal verification solution.”
