Magma Design Automation Inc. has introduced the Talus Vortex FX, an IC implementation solution that utilizes distributed computing for place-and-route.

Mark Richards, senior technical marketing manager, design implementation business unit, Magma Design Automation, explained that the Talus Vortex FX is a distributed place-and-route implementation tool that leverages the Talus Vortex technology in each of the distributed partitions. He said, "Managing, synchronizing and ensuring optimum quality of results (QoR) for these partitions and the design as a whole is the overriding technology that marks the tool out against the rest of the P&R space."

Talus Vortex FX is claimed to be up to three times faster than Magma's Talus 1.2, enabling designers to implement multimillion-cell designs flat and to generate 2 million to 5 million cells per day with crosstalk avoidance, advanced on-chip variation and multimode multicorner analysis, all with existing hardware resources. Thus, Talus Vortex FX is suitable for large, complex advanced-node designs.

Commenting on Talus Vortex FX performances versus Talus 1.2, Richards declared, "The throughput from design to design will always vary with any number of factors including things as simple as high placement utilization to more esoteric reasons like complex MVDD requirements or highly channeled designs with difficult to meet topology and timing constraints. But across a broad number of real world designs that Talus Vortex 1.2 has been benchmarked on, we see consistent throughput at over one million cells per day."

Inside the tool
Talus Vortex FX integrates the Distributed Smart Sync technology to enable concurrent implementation management and smart synchronization of large designs across a network of machines. Richards explained that this technology is aimed at optimally partitioning the design across the available (automatic or manually driven) resources to ensure maximum throughput whilst delivering best in class QoR. All of the normally complex tasks related to timing and physical partitioning is automatically handled by the tool.

Also, the COre technology is very much still embedded in the Talus Vortex flow, Richards noted. "However, that flow paradigm has been further optimized to ensure optimal crosstalk convergence with the best throughput. This includes track based optimization earlier in the flow and the new MX global router with its significant throughput, capacity and QoR enhancements. The end goal being to ensure that runtime costly post-route optimization steps are minimized as much as possible."
