EEsof EDA software links to Cadence Virtuoso for RFIC co-design

January 09, 2015 // By Graham Prophet
The latest release of Keysight Technologies’ Advanced Design System (ADS) software, ADS 2015 extends silicon RFIC interoperability with Cadence’s Virtuoso, alongside GoldenGate-in-ADS, and other capabilities intended to increase design efficiency.

The convergence of GaAs and silicon design, coupled with the move to higher frequencies in silicon designs and their tighter integration into packages or modules has, says Keysight, increased the need for an interoperable co-design flow. Silicon RFIC interoperability in ADS enables users to edit and simulate schematic designs created in either Virtuoso or ADS. Users also can open a Virtuoso IC layout cell view in ADS, instantiate the cell within a package or module, and then run an electromagnetic simulation on the complete design to validate its overall system performance.

ADS-Virtuoso interoperability works on top of a baseline Virtuoso process development kit (PDK). ADS 2015 is backed by broad PDK support from a number of RF Silicon foundries. Interoperability-enabled PDKs are available from TSMC, GLOBALFOUNDRIES, TowerJazz, IBM, and IHP, and have been validated by customers as part of Keysight's alpha program.


To provide users a complete Silicon RFIC design platform, the GoldenGate simulation, analysis and verification solution for large-scale RFIC circuit design, is now integrated into ADS 2015. “With the availability of GoldenGate-in-ADS and foundry interoperable PDKs, we have given our customers access to our leading silicon RFIC circuit simulation technology directly within the ADS Platform,” said Joe Civello, ADS product manager for Keysight EEsof EDA. “...the new RFIC cockpit in ADS allows users to use the same Virtuoso simulation testbench and settings directly in ADS.”

Additional new capabilities and enhancements available in ADS 2015 include:

· DDR Bus Simulator

· RFIC cockpit that expands the ADS schematic control block use model to a complete RFIC simulation cockpit

· 2-16x faster FEM simulation performance improvements

· Layout and layout verification improvements

· Numerous usability, performance and productivity improvements
