Cadence Virtuoso layout automation services
SkyCadEda builds layout automation for custom IC teams that draw and verify physical designs in Cadence Virtuoso. Our SKILL scripts, PCells and layout generators take over repetitive manual edits, build design rules into the geometry, and shorten layout closure.
Scope
Engineering scope
Built around your existing methodology.
SKILL-based layout generators
Custom SKILL scripts that automatically generate layout from schematic netlists, device arrays, and structured patterns. Parameterized layout generators produce DRC-clean placement in minutes rather than hours of manual drawing.
PCell development and libraries
Parametric cell development for Cadence Virtuoso that captures layout intent in reusable, foundry-aware components. PCells encode design rules, spacing constraints, and geometry variations so designers can instantiate correct-by-construction layout objects.
Automated layout migration
Automated migration of layout databases across process nodes, technology variants, and design rule sets. Scale geometries, remap layers, and adapt connectivity while preserving layout intent and meeting target foundry requirements.
Batch layout processing
Scripted batch operations for layout manipulation — cell flattening, layer remapping, text annotation, pin alignment, guard ring insertion, and fill generation. Process hundreds of cells consistently without manual intervention.
Outcomes
What you get
A deployment-ready result, handed over to your team.
- Reduce layout cycle time by 40–70% through automated placement, routing, and manipulation tasks.
- Enforce design rule compliance with PCells and generators that encode foundry constraints directly.
- Improve layout reuse across projects with parameterized cells and migration automation.
- Eliminate manual errors in repetitive tasks like fill, guard rings, and pin placement.
Accelerate custom IC layout with automation
Custom IC layout is one of the most time-intensive stages of analog and mixed-signal design. Manual polygon editing, repetitive cell instantiation, and iterative DRC fixes consume engineering hours that could be spent on design optimization. SkyCadEda's layout automation services replace manual workflows with tested SKILL scripts, PCells, and batch tools that produce consistent, foundry-correct layout in less time.
Layout generators and template-based design
Our layout generators take schematic connectivity and design parameters as input and produce DRC-clean layout automatically. For common structures — current mirrors, differential pairs, capacitor arrays, resistor banks, and ESD structures — template-based generators deliver layout in seconds. Each generator encodes foundry design rules, matching constraints, and routing preferences so output is immediately usable in your design flow.
PCell ecosystems for design teams
We build complete PCell ecosystems that go beyond basic device parameters. Our PCells include built-in DRC checks, connectivity-aware pin placement, automatic guard ring insertion, and technology-aware variant support. Teams instantiate PCells, adjust parameters, and get layout that is correct by construction — reducing the iteration loop between layout and verification.
Integration with verification and sign-off
Layout automation does not end with geometry generation. We integrate SKILL-based automation with DRC/LVS verification flows, enabling scripts to read Calibre or Pegasus results, identify violations, and apply automated fixes. This closed-loop approach accelerates sign-off by reducing the manual effort required to resolve verification errors.
FAQ
Questions before engagement
What is layout automation in custom IC design?
Layout automation uses scripting and parametric tools to generate, manipulate, and verify physical layout in semiconductor design. Instead of manually drawing every polygon, designers use automated generators, PCells, and batch scripts to produce correct layout faster and with fewer errors.
How does SKILL scripting improve layout productivity?
SKILL is the native scripting language for Cadence Virtuoso. It gives designers and CAD engineers direct access to layout databases, design rules, and editor commands. SKILL scripts can automate repetitive tasks like array generation, guard ring placement, and DRC fix-up, reducing hours of manual work to minutes.
What is PCell development and why is it important?
PCells (Parametric Cells) are programmable layout objects in Cadence Virtuoso whose geometry is defined by parameters rather than fixed shapes. PCell development creates reusable components — transistors, resistors, capacitors, custom structures — that automatically adapt to parameter changes while respecting foundry design rules.
Which Virtuoso tools does SkyCadEda automate?
We automate across the full Cadence Virtuoso suite including Virtuoso Layout Suite (VLS), Virtuoso Studio, and the XL and GXL automation features. Our SKILL scripts work with the layout editor, constraint-driven routing, floorplanning, and Virtuoso integration with verification tools like Calibre and Pegasus.
