Router improves design and manufacturability

STMicroelectronics has taped out a 65nm next-generation mixed-signal communications design using the Cadence Space-Based Router.

STMicroelectronics has taped out a 65nm next-generation mixed-signal communications design using the Cadence Space-Based Router and achieved a faster tapeout with improved routing, design performance and manufacturability.

At 65nm and below, complex design rules are needed to address design density, electrical performance targets and manufacturing effects.

Earlier generations of routers simply cannot keep pace with these rules.

Cadence's new Space-Based Router extends automated routing technology beyond shape-based and gridded routing with its advanced gridless, three-dimensional, space-based architecture.

This provides superior modelling of advanced processes and addresses increasingly interdependent design constraints, providing maximum control and exceptional results early in the design process.

Especially suitable for high-performance, custom digital, and mixed-signal designs, the Cadence Space-Based Router also enables incremental in-core electrical analysis, design for manufacturing (DFM), and design for yield (DFY) optimisation.

"The Cadence routing solutions have helped us address the interconnect issues of complex analogue/RF chips and maximise productivity on many of our custom, analogue, and mixed-signal designs", said Jean-Paul Morin, analogue/RF CAD Manager at STMicroelectronics.

"The Space-Based Router's ability to precisely model neighboring shape configurations was crucial to our recent tapeout of a 65nm RF mixed-signal chip, providing us with a sophisticated manufacturing modelling and constraint system and high-capacity specialty-routing features".

"Companies such as ST, that are working at 65nm, 45nm and below, are facing critical design and manufacturing concerns including time to convergence, process variability and complex design rules", said Richard Brashears, Corporate Vice President, Manufacturing Modelling and Implementation Group, at Cadence.

"The steady stream of successes that we are seeing from ST and other partners who have adopted the Cadence Space-Based Router, demonstrates its applicability in solving these complex and demanding issues".
