New Electronics – Cadence Automates Custom/Analog Design Migration on TSMC’s Advanced Technologies

Cadence Design Systems, in conjunction with TSMC, has developed a node-to-node design migration workflow based on its Virtuoso design platform for custom/analog IC blocks that utilize TSMC’s advanced process technologies.

Cadence and TSMC R&D teams have worked together to ensure that the Virtuoso schematic editor and layout editor automatically migrate a source design on TSMC N5 and N4 process technologies to a new design on TSMC N3E process technology.

Early analog design IP trials of the new migration flow found design time on common analog blocks to be over 2.5x faster compared to manual migration.

The Virtuoso Application Library Environment schematic migration solution, which is integrated with the Virtuoso design platform, automatically migrates cells, parameters, pins, and wiring from a source schematic from one process node to another technology. The target scheme is then tuned and optimized using the simulation environment and circuit optimization technology from the Virtuoso ADE product suite to verify that the new scheme meets all of the necessary measurement targets.

The Virtuoso Layout Suite supports reusing existing layouts on a given process technology to quickly recreate a migrated layout on a new process technology, using custom location and route automation. Using Virtuoso Layout Suite templates, TSMC’s analog mapping technology, and Virtuoso Design Platform’s routing technology, designers are able to automatically recognize and extract groups of devices in an existing layout and apply templates to similar groups in the new layout.

“Through our continued collaboration with Cadence, we enable our customers to improve productivity and accelerate design closure when migrating node-to-node design migration of analog blocks within the Virtuoso design platform. “, said Dan Kochpatcharin, manager of the design infrastructure management division. at TSMC.

“With the availability of our enhanced PDKs, we enable our customers to easily migrate custom/analog blocks from one of our widely used processes to another and benefit from the power, performance and enhancements of our latest technologies. . ”

“Working closely with TSMC, our customers now have access to the most sophisticated custom/analog location and route automation and migration capabilities within the Virtuoso design platform,” said Tom Beckley. , Senior Vice President and General Manager of Custom IC, IC Packaging, PCB and Systems Analysis Group. “This new, easy-to-use, node-to-node design migration technology addresses a key requirement for our customers’ most challenging custom analog designs.”
