Engineering Services

Silicon-to-system engineering services.

From front-end RTL specification to DRC-clean GDSII sign-off and custom EDA software — Vidian delivers end-to-end semiconductor design capabilities.

RTL Design & Architecture

Our RTL design team architects and implements digital blocks from micro-architecture through synthesis. We handle everything from simple peripheral controllers to complex multi-clock-domain SoC subsystems. Every design goes through lint, CDC, and synthesis checks before handoff — because tape-out surprises are expensive.

Key Capabilities
Micro-architecture Definition: Translating high-level functional specs into detailed block-level micro-architecture documents with trade-off analysis.
RTL Coding (Verilog & SystemVerilog): Writing clean, synthesizable, lint-clean RTL following industry coding standards. Parameterized, reusable, and well-commented.
Clock Domain Crossing (CDC) Design: Safe CDC techniques — synchronizers, FIFOs, handshake protocols. Full CDC analysis and reporting before synthesis.
Lint, CDC & Synthesis: Running SpyGlass Lint, CDC checks, and synthesis with target libraries. No surprises at the back-end handoff.

Design Verification & UVM

We build UVM-based verification environments from scratch or augment existing teams. Our methodology is coverage-driven: every test plan starts with a coverage model, and every regression ends with a coverage report. From block-level IP to full-chip SoC verification — we find the corner cases that directed tests miss.

Key Capabilities
UVM Testbench Architecture: Designing modular, reusable UVM environments — agents, scoreboards, sequences, and coverage collectors for any bus protocol.
Constrained-Random Stimulus: Building intelligent constraint models that explore the state space efficiently, hitting corner cases directed tests would never reach.
Functional Coverage & Closure: Coverage-driven verification planning. Tracking functional coverage, assertion coverage, and code coverage to 100% closure.
Formal Verification: Applying formal property verification (FPV) on critical control paths, CDC logic, and protocol compliance — exhaustive proof, not sampling.

Design for Test (DFT)

We architect and implement DFT solutions that minimize area overhead while maximizing fault coverage. Our team handles scan insertion, ATPG pattern generation, memory BIST integration, boundary scan, and compression — ensuring your chip is testable, manufacturable, and yield-ready at the foundry.

Key Capabilities
Scan Architecture & Insertion: Full-scan and partial-scan architectures. Scan compression (OPMISR+, broadcast scan) to reduce test time and tester memory.
ATPG & Fault Coverage: Automatic test pattern generation with stuck-at, transition, and path-delay fault models. Coverage analysis and gap closure.
Memory BIST (MBIST): MBIST controller insertion for SRAM, ROM, and register files. March algorithm selection, repair analysis, and redundancy.
JTAG & IEEE 1500: IEEE 1149.1 boundary scan implementation. IEEE 1500 core test wrappers for hierarchical test access.

Physical Design & Timing Closure

Our physical design team takes synthesized netlists and transforms them into tape-out-ready GDSII. We handle floorplanning, power grid design, placement, clock tree synthesis, routing, and full sign-off STA across all PVT corners. We close designs at nodes from 180nm down to 5nm, across foundries.

Key Capabilities
Floorplanning & Power Grid: Die size estimation, macro placement, power mesh design, IR drop analysis. Optimizing for routability and timing from day one.
Clock Tree Synthesis: Building balanced, low-skew clock trees. H-tree, mesh, and multi-point CTS strategies for high-frequency designs.
Place & Route: Timing-driven placement, global and detailed routing, DRC fixing, antenna violation repair. ECO routing for last-mile timing fixes.
STA & Sign-off: Multi-corner, multi-mode static timing analysis. Setup/hold closure, OCV/AOCV derating, signal integrity, and IR drop sign-off.

Software Engineering & EDA Tooling

Most software teams don't understand silicon. We do. We build custom EDA workflow automation, design management dashboards, regression frameworks, and full-stack web applications for semiconductor teams. Every line of code is written with an understanding of what happens in the foundry.

Key Capabilities
EDA Workflow Automation: Custom scripts and pipelines that glue together your EDA toolchain — regression launchers, report parsers, auto-triaging systems.
Design Management Dashboards: Web-based dashboards for tracking project milestones, coverage metrics, bug counts, and tape-out readiness — real-time.
Custom Tool Development: Building internal tools that fill gaps in commercial EDA flows — custom checkers, format converters, visualization utilities.
Full-Stack Web Apps: React/Next.js applications with TypeScript, PostgreSQL, and cloud deployment — for any engineering workflow need.
