Fast Exploration for Analog Design

Reaching technology limits with innovative circuit topologies is the work of the Analog Designer.

Enabling fast technology-independent analog design is the work of ID-Xplore from Intento Design.

A typical design flow requires going through "manual" sizing and biasing with lots of time consuming iterations. This empiric approach results in days of work before getting a correctly sized schematic. Only after accessing the technology PDK through ADE XL simulation can the design trade-offs be fully assessed. As semiconductor technologies have advanced, EDA innovation for DC bias and sizing has not kept pace.

Today, Intento Design ID-Xplore tool uses graph-based disruptive innovation to provide rapid, specification driven DC bias and transistor sizing. Using Cadence Virtuoso Schematic Composer Constraint Editor, design constraints plus circuit topology are used to generate a graph for fast design space exploration in any technology. ID-Xplore provides design curves showing the performance capabilities and design trade-offs within the technology and the design constraints.

The patented graph approach incorporates full technology complexity using industry standard simulators at transistor level. Specification and technology constraints drive the design exploration, ensuring a correct-by-construction DC bias operating point.

Analog Designers are empowered with fast exploration capabilities in their targeted design space to get a correct and highly performant sized schematic in minutes.
