CAD- Si Pkg Board
CAD – Si, Package & Board involves developing and maintaining design tools, automation flows, and methodologies that support the complete path from silicon layout to package and PCB integration. At Yoctozant, we enable seamless interoperability between IC design, packaging, and board-level systems by building robust CAD frameworks, creating PDKs, managing EDA environments, and automating multi-domain workflows. Our CAD solutions ensure accuracy, consistency, and efficiency across the entire design ecosystem—accelerating development and improving product reliability.
01
Methodology Development
We define robust, scalable methodologies for Si, Package, and Board co-design flows, covering layout planning, DRC rule integration, stack-up design, routing strategy, and multi-die interface mapping. Our approach ensures high design reliability with minimal iteration cycles.
- Synthesis, floorplanning, placement, routing, CTS, extraction, and sign-off—built as unified, automated, and version-controlled flows.
- Automated rule decks, check setups, constraint enforcement, and multi-technology support.
Automation
We develop automation scripts and CAD frameworks for placement, routing, constraint validation, SI/PI analysis setups, BOM generation, documentation, and release workflows—reducing manual work and enhancing throughput.
- Script-driven flows for macro placement, layer planning, congestion reduction, and optimal routing strategies.
- Auto-check frameworks for length matching, impedance, spacing rules, and power integrity compliance.

03
QA and Validation
Our engineers conduct thorough validation checks, including spacing rules, thermal limits, high-speed routing constraints, impedance continuity, crosstalk risk, PDN stability, and manufacturability compliance. We help detect issues early, ensuring a robust final package and board layout.
- Thermal & Mechanical Rule Analysis ensuring safe operating temperatures and structural stability.
- High-Speed Routing Validation for signal integrity, timing performance, and jitter-free operation.
Release & Support
We provide end-to-end release management, database version control, ECO handling, supply chain readiness, and continuous engineering support. Our release cycles focus on stability, reliability, and smooth handoff to fabrication and assembly partners.
- Final checks, packaging, data consolidation, and secure distribution to fabrication or OSAT partners.
- Centralized version management, ECO handling, revision tracking, and controlled design updates.
