Virtuoso SKILL Development
SkyCadEda provides professional Cadence SKILL programming services for custom IC design teams. From layout automation and PCell development to custom GUIs and simulation flow scripting, we write production-grade SKILL code that integrates seamlessly with Virtuoso and the broader Cadence tool ecosystem.
Custom SKILL routines for automated layout generation, cell manipulation, constraint-driven editing, and batch processing. Reduce manual layout effort with parametric automation scripts tailored to your design methodology.
Parameterized cell development in SKILL and PCellXL for automated layout generation. Custom PCells for analog, mixed-signal, RF, and standard cell designs with full DRC compliance and foundry compatibility.
Custom CDF callbacks for device parameterization, netlisting, simulation integration, and design rule validation. Ensure correct-by-construction device configuration across your design flow.
Virtuoso GUI extensions using SKILL and Qt integration. Custom forms, toolbars, menu extensions, and interactive design tools that improve designer productivity and enforce methodology compliance.
Cadence SKILL is the most powerful scripting language in the custom IC design ecosystem. When used effectively, it can transform design productivity — automating repetitive tasks, enforcing methodology compliance, and enabling design reuse across projects. SkyCadEda's SKILL scripting services deliver production-quality code that integrates into your existing Virtuoso environment.
Our SKILL engineers have deep expertise in the Virtuoso database model, layout editing APIs, schematic access, CDF framework, and simulation integration. We write clean, documented, version-portable code that your CAD team can maintain and extend.
Layout generators for repetitive structures (arrays, matching patterns, guard rings), automated DRC-clean cell assembly, constraint-driven placement and routing utilities, batch parameter sweeps for simulation, interactive layout editing tools with custom bindkeys, design review and annotation utilities, and netlist post-processing for simulation setup.
For teams using both Cadence and Synopsys environments, we provide cross-platform automation using SKILL, Tcl/Tk, and Python. This includes unified scripting interfaces, tool-agnostic data exchange utilities, and automation that bridges Virtuoso and Custom Compiler workflows.
SKILL is the scripting language built into Cadence EDA tools, primarily Virtuoso. It allows engineers to automate design tasks, create custom tools, extend the Virtuoso interface, and build parameterized cells (PCells). SKILL is based on Lisp and provides deep access to Virtuoso database objects, layout editing, schematic capture, and simulation environments.
We build a wide range of SKILL tools: layout generators and automation scripts, PCells and PCellXL components, CDF callbacks and device configuration, custom Virtuoso GUI extensions, batch processing utilities, design rule check scripts, netlisting and simulation flow automation, and interactive design aids for analog/mixed-signal layout.
Yes. We write traditional SKILL PCells as well as PCellXL (the newer, compiled PCell format in Virtuoso). PCellXL offers better performance for complex parameterized cells and is recommended for production PDK development.
We write version-aware SKILL code that works across Virtuoso IC23, IC25, and Studio environments. We handle API differences, deprecated functions, and version-specific behaviors to ensure portability.
Yes. While SKILL is our primary focus for Cadence tools, we also provide Tcl/Tk and Python scripting for Synopsys Custom Compiler, ICC2, and other Synopsys platforms. We can build cross-tool automation that bridges Cadence and Synopsys environments.
