DRC/LVS Deck Engineering
Rule deck authoring and adaptation for foundry and project-specific sign-off requirements. Support for Calibre SVRF/TVF, Pegasus, Assura, and PVS rule formats with full DRC, LVS, and RCX coverage.
DRC LVS Sign-off
Physical Verification Services for Faster Sign-off Closure
SkyCadEda supports physical verification teams with practical deck engineering and flow automation for high-volume custom IC programs. We focus on repeatable sign-off execution across Calibre, Pegasus, Assura, and PVS environments. Our engineers have written and optimized rule decks for foundries, IDMs, and fabless teams on nodes from 180nm to advanced FinFET.
Runset Performance Optimization
Structured optimization of runtime bottlenecks for better verification turnaround on large designs. Parallel execution configuration, memory optimization, and selective rule execution strategies.
Waiver and Error-Handling Automation
Flow utilities for waiver management, result triage, and standardized reporting across revisions. Automated error classification and interactive debugging workflows for faster resolution.
Cross-Tool Verification Alignment
Consistent behavior across Pegasus, Assura, Calibre, and PVS execution models. Deck porting between verification platforms with result correlation and regression testing.
Expected Engagement Outcomes
- Improved predictability in DRC/LVS closure cycles.
- Lower engineering overhead in repetitive verification tasks.
- More traceable and audit-friendly sign-off handoff.
- Better utilization of compute resources for verification jobs.
Comprehensive DRC/LVS Rule Deck Engineering
Physical verification is the final gate before tape-out. Errors in DRC or LVS decks can delay projects by weeks or, worse, result in silicon failures. SkyCadEda provides expert rule deck engineering services that ensure your verification flows are accurate, fast, and maintainable.
Our team writes and maintains rule decks for the full spectrum of physical verification checks: geometric DRC (width, spacing, enclosure, area, density), connectivity LVS (net matching, device extraction, pin alignment), parasitic extraction (RCX, QRC), ERC (electrical rule checks), antenna checks, and reliability verification (EM, IR drop).
Verification Flow Automation
Beyond rule deck authoring, we build automation around the verification workflow: batch execution scripts, result parsing and reporting dashboards, waiver management systems, and regression testing frameworks. This automation reduces manual effort and improves sign-off predictability.
Foundry Qualification Support
For foundries and IDMs qualifying new process nodes, we support rule deck development against foundry design rule specifications, golden layout correlation, and third-party tool cross-verification to ensure decks meet foundry sign-off requirements.
Frequently Asked Questions
What physical verification tools does SkyCadEda support?+
We support all major physical verification platforms: Siemens Calibre (SVRF and TVF rule decks), Cadence Pegasus and Assura, Synopsys IC Validator, and Siemens PVS. We write, optimize, and maintain rule decks across these platforms.
What is DRC and LVS in semiconductor design?+
DRC (Design Rule Checking) verifies that a chip layout meets the foundry manufacturing constraints — minimum widths, spacings, enclosure rules. LVS (Layout vs. Schematic) verifies that the physical layout matches the intended circuit schematic, checking connectivity, device parameters, and hierarchy. Both are mandatory for tape-out sign-off.
Can you port rule decks between verification tools?+
Yes. We regularly port rule decks between Calibre, Pegasus, Assura, and PVS. This includes SVRF-to-TVF conversion, rule-by-rule mapping, and result correlation to ensure consistent verification outcomes across platforms.
How do you optimize verification runtimes?+
We use several strategies: selective rule execution for incremental checks, parallel processing configuration, memory-aware partitioning, layout preprocessing, and hierarchical verification setup. Typical optimizations reduce runtime by 30-60% on large designs.
Do you support advanced node verification (FinFET, GAA)?+
Yes. We have experience with advanced node rule decks including FinFET and GAA processes. These require complex multi-patterning checks, coloring rules, and advanced density analysis that we handle as part of our verification service.
