36 DESIGN007 MAGAZINE I SEPTEMBER 2025 A RT I C L E by K i r k F a b b r i , S i e m e n s E DA T oday's designs are as complex as ever, and engineers face tough decisions every day. Simulation and verification teams are confronted with a three-fold challenge: understanding the underlying theory, mastering the tools, and apply- ing best practices. Engineers need to navigate a vast and ever- changing cast of design and simulation tools, often with overlapping functionality. Additionally, there may be a preference for a mix of software tools, even within the same company, leading to a lack of standardization and varying levels of integration. All these challenges can lead to confusion, missed requirements, and project delays due to inefficient workflows, often leading engineers to delegate the task to specialists, either in-house or Taking Control of PCB Verification One Step at a Time external, rather than tackling it themselves. The inherent fear of complexity and the influence of experts focused on minute details amplify the re- luctance to engage with essential tasks like signal integrity analysis. But this need not be the case. Progressive verification in PCB design offers a strategic, dynamic verification process and ad- dresses the complexities of modern electronics design. By prioritizing tasks based on their complexity and time requirements, design teams can efficiently manage their resources and reduce the risk of project delays. This approach not only helps in catching errors early but also alleviates the bottleneck created by reliance on external or in-house experts. Let's look at how this dynamic process works in broad strokes.
