Magma Unveils Talus 1.2
Magma Design Automation unveiled Talus 1.2, a next-generation integrated circuit implementation solution that accelerates the design cycle of systems on chip. The new Talus system enables engineers to implement 1 million to 1.5 million cells per day on large designs or blocks of 2 million to 5 million cells – with crosstalk avoidance, advanced on-chip variation (AOCV) and multi-mode multi-corner (MMMC) analysis enabled. Already silicon-proven at the 40-nanometer (nm) node, Talus is currently in use for complex 28-nm designs. With these latest enhancements, Talus is primed to handle the challenges of designing at the 20-nm process node and beyond.
Talus 1.2 leverages faster, more accurate routing, timing and extraction technologies and advanced capabilities to deliver five to six times faster turnaround time, including:
• Talus MX Router: Offers enhanced global, track and detailed routing capabilities, convergent timing through the flow, and eliminates DRC violations.
• Talus MX Timer: Based on Magma's next-generation sign-off timing analysis technology, enables faster more accurate timing analysis.
• Talus MX Extractor: Based on Magma's latest high-speed, multi-corner extraction technology, provides faster, more accurate extraction.
• Concurrent MMMC optimization: Manages five times as many timing scenarios than traditional solutions, while providing a 10X runtime improvement.
• AOCV: Ensures tight timing correlation throughout the flow.
• Crosstalk Avoidance: Detects and corrects crosstalk violations during optimization and implementation.
Key enabling technologies in Talus 1.2 include the new Talus MX timing and extraction engines based on underlying technology borrowed from Magma's next-generation sign-off timer, Tekton, and sign-off extractor, QCP . Used consistently throughout Talus 1.2's RTL-to-GDSII flow, these analysis engines are fast, accurate and have significantly higher capacity. They offer new features such as AOCV and MMMC analysis, ensuring tight timing correlation throughout the flow. When combined with Tekton and QCP, Talus 1.2 provides sign-off-accurate analysis during implementation, eliminating timing ECOs and resulting in faster design closure.
For implementation at 28 nm and below, it's not uncommon for designs to require the analysis of many different timing scenarios. Magma defines timing scenarios as the number of process corners multiplied by the number of timing modes. Most solutions can only handle five to eight scenarios during implementation. Talus 1.2 performs concurrent MMMC on a single machine and can manage five times more scenarios than traditional solutions, while improving runtime by 10 times.
Talus 1.2's new routing technology addresses routing challenges at 28 nm and below, where managing crosstalk in particular becomes more difficult. Fixing crosstalk too late in the flow results, in the best case, in higher cell area and elevated leakage. In the worst case, it results in a design that will not close. Talus1.2 avoids this by identifying and controlling crosstalk throughout implementation, providing a much more convergent flow with far fewer timing surprises. Unlike other approaches, Talus 1.2 delivers far shorter runtimes and more robust designs, without increasing area and leakage.
The combination of Talus 1.2's new technologies enables designers to deliver high-performance designs quickly. For example, a networking company was able to implement a 40-nm, 2-million-instance design with 10 sign-off scenarios in just 2 days with full CCS, MMMC and crosstalk analysis enabled.
