Improve Productivity Over 50% With SKillCAD IC Layout Automation Suite for Cadence Virtuoso 

Looking to Improve Chip Time-to-Market? Look No Further. 

Cadence Virtuoso + SkillCAD IC (LAS) have become the preferred standard layout environment for analog, RF and mixed-signal designs. Over 80% of the major analog and mixed signal semiconductor companies now use SkillCAD to improve designers productivity while reducing Tape-Out Delays. 

IC Layout Automation Suite (LAS) is a collection of 120+ user guided and auto routing commands that can boost layout productivity on average 30-50%. SkillCAD's proprietary "correct and optimized by construction" eliminates design rule violations and automates complex error prone layout implementation while reducing tape-out time.

SkillCAD's IC LAS integrates seamlessly with Cadence Virtuoso Layout Suite, allowing:

  • Customers to never have to leave Virtuoso environment while designing 
  • Use of same tech rope files 
  • Access to additional 120+ commands not offered in Virtuoso, SkillCAD addresses many specific design styles and common tasks that designers must perform 

IC Layout Automation Suite (LAS) Overview video:

  • SkillCAD on average provides a 30-50% increase in Virtuoso layout designers productivity.

  • SkillCAD’s layout commands improve layout quality while reducing complex function to a few simple clicks.

  • SkillCAD has over 120 correct by construction commands that have significantly increased productivity and reduced our time to tape-out.

  • SkillCAD seamlessly integrates with Cadence Virtuoso, our layout designers were using IC LAS the same day it was installed.

The SKILLCAD Index Guide was developed to help designers to know what SKILLCAD Commands are available and where to find the commands on the SKILLCAD tool bar or menu. It also contains a brief description of the commands, indicates which commands are most often used by layout designers, and which commands should work completely or partially in advanced nodes (N10, N7, N5, etc.).

The SKILLCAD Topical Guide was developed to help designers to know where to find the SKILLCAD commands to complete common layout tasks and provide training materials that teach how to use the commands. The topics, or tasks, in the Topical Guide are grouped alphabetically under main headings such as “Arrays”, “Buses”, “Calculations and measurements”, etc.

Command Groups


These tools enable a designer to quickly chop and modify existing instance arrays. The modifying region can be defined by a rectangle, polygon, or another shape.

Bus Routing

The bus routing tools are one of the largest groups in SkillCAD, since bus creation and modification is one of the most time- consuming tasks in custom layout design.

Calculation and Measurement

This is a group of tools that facilitate and simplify common measuring tasks, such as distance, area, and perimeter measurements.

Connecting Metal to Devices

This is a set of tools for easily connecting metal to multi-contact MOS devices. Tools are included to connect:Sources and/or drains to backbone metal.

Density Check

The density checking tools facilitate the measurement of specified layer densities in a defined region. The regions can be defined by: Polygons, Rectangles, Coordinates, Selected regions.

Device Placement

These tools simplify the tedious tasks of placing and modifying the placements of matched devices arrays.

Metal Path and Path Segment

The metal path and path segment (wire) tools are designed to simplify and automate the creation and connection of single metal routes.

Metal Coloring

This is a collection of tools to simplify the generation of complementary metal routes, used to maximize routing area utilization in advanced, sub-micron processes.

Multi-part Path and Guardring

The multi-part path tools simplify and automate the creation of paths and rings containing multiple layers joined by contacts and/or metal vias.


The net tools simplify the selection and highlighting of metal nets, through all levels of hierarchy.


The pin tools simplify and automate time-consuming layout processes such as: Aligning pins to a Boundary.

Shape Handling

The shape handling tools contain routine shape conversion tools, as well as advanced shape creation tools such as: Copying shapes from a background view to the current view.

Slotted Metal

The slotted metal tools simplify and automate the creation and modification of wide slotted metals.

Dummy Fill

This is a set of tools to simplify the creation of dummy fill in a layout design. The fill shapes can be created in: A defined area, a selected region, or under a specified layer.

Flat Panel Layout

The flat panel layout tools were designed specifically for the rigors of flat panel design. Since metal routing is a major concern of flat panel layout.


The label tools contain applications to create and re-create labels on various layout objects.

Track Routing

The track routing tools automate the creation of metal track routing, used in advanced manufacturing processes.


The via tools contain applications to simplify and automate common via operations such as creating and modifying via arrays.


The viewing tools are designed to help the layout designer see circuit blocks in ways different from the standard layout window.

Layer Handling

This group of tools is useful for viewing and identifying layers in a layout view.

Increase design productivity, while reducing tape-out delays.
