CAD-PD/DFT
CAD–PD/DFT services involve developing automated flows, methodologies, and tool frameworks that support Physical Design (PD) and Design-for-Test (DFT) teams. At Yoctozant, we build scalable CAD infrastructures for floorplanning, synthesis, timing, routing, and sign-off, along with robust DFT automation for scan insertion, ATPG, MBIST, and validation. Our CAD–PD/DFT solutions ensure consistent, repeatable, and high-quality design processes—reducing manual effort, improving accuracy, and accelerating tape-out readiness.
01
Methodology Development
We establish scalable PD and DFT methodologies tailored to your process node, design complexity, and EDA environment. Our flow architecture supports both hierarchical and flat integration approaches, enabling predictable timing closure and seamless scalability across projects.
- We define flows for synthesis, floorplanning, placement, CTS, routing, extraction, SI analysis, EM/IR, and sign-off—ensuring every step is optimized for PPA.
- We create constraint management guidelines, ECO methodologies, and sign-off processes to help engineers meet timing faster.
Automation
From synthesis to place & route automation, timing checks, DRC/LVS analysis, ATPG pattern generation, and debug workflows—we build scripts and automated frameworks to reduce manual effort and accelerate sign-off.
- We build automated scripts that cover RTL synthesis, floorplan generation, placement, CTS, routing, and extraction.
- Automated flows for running Calibre, Pegasus, or other sign-off tools ensure fast and clean verification cycles.

QA Validation
We perform rigorous flow validation across timing, power, congestion, clock-tree, IR-drop, scan insertion, and test coverage metrics. Our validation ensures closure efficiency and production-grade readiness before tape-out.
- We perform detailed timing reviews across all corners, modes, and scenarios—ensuring clean, convergent timing closure.
- Thorough checks ensure reliability, power integrity, and congestion-free routing.
