Spice In: the Unified Analog Import Tool

January 15, 2007, Vivek Astvansh - Cadence

This paper introduces you to Spice In - the unified analog import tool that will import SPICE/Spectre/CDL and other SPICE-like analog net lists into the DFII flow. By bridging the flow gap, Spice In will promote the use of various Cadence tools in the Environment, Simulation, and Verification domains. Spice In uses an extensible architecture that can be enhanced to read any Spice-like analog net list. The resulting DFII view can be a simple net list view, or a schematic view.Read more »
Higher Quality Designs – a Configuration Management Approach

January 9, 2007, Rom Bronfman - Saifun Simiconductors

The challenge in complex chip architectures, such as Saifun's flash memories, lies in synchronizing between several cross-dependant sub-projects, from PDK translation, through custom circuit, logic and layout design, to verification and backend analysis. In Saifun we met this challenge by creating a multi-design-flow environment based on strict methodologies enforced through policy checks, thus buffering between inputs and outputs of different flows and improving design quality. The system, which is implemented using Synchronicity's configuration management tools and integrated into Cadence's design environment, enables Saifun to successfully deliver several high quality products per year.Read more »
