Verifies and generates SDC timing constraints for ETM-based place-route and static timing analysis
LAS VEGAS — (BUSINESS WIRE) — June 3, 2019 — DESIGN AUTOMATION CONFERENCE -- Ausdia, the leading developer of design constraints verification and management solutions that complement timing signoff for complex system-on-chip (SoC) designs, introduced an exciting new capability to its comprehensive Timevision™ solution at the 56th Design Automation Conference (DAC) 2019.
Timevision FlatChecker closes the coverage gap between “flat” timing closure and signoff and “timing-model/extracted timing models (ETM)” based timing, enabling full-chip static timing analysis (STA) and place-and-route engineers to ensure their ETM-based timing flows correspond exactly to the complete, flat timing signoff.
Today, full-chip place-and-route specialists may wrestle with too many over- or under-constrained paths at the full-chip SoC level, which can affect PPA optimizations and prompt additional ECO iterations once flat timing is enabled. Timevision FlatChecker pinpoints these variances automatically without any designer input, and corrects issues with rich rule-checking system and debugging features. Additionally, the FlatChecker addition to Timevision can automatically generate new SDC design constraints to enable ETM-based timing flows, if no ETM-enabled SDC constraints are available.
SoC designs at 10nm and 7nm are getting larger and more complicated as more and more functionality is placed into designs, requiring virtually all designs to be implemented hierarchically. However, at the full-chip level, designers must either use flat (full netlist) STA analysis, which can extend turn-around-time (TAT), or use ETMs to reduce data volume and provide significant TAT improvement. In order to enable full-chip place-and-route timing closure, ETM-based methods become imperative, requiring a solution to both generate and verify the SDC timing constraints used so that PPA is optimal and final ECO spins are minimized. FlatChecker ensures the SDC constraints used in ETM-based place-and-route, and signoff, are equivalent to the fully-flat version of the same design, as well as generating SDC constraints with selected blocks changed to ETM format.
“Our customers are completing their SoC designs using hierarchical design flows, and using every trick in the book to improve their turn-around times (TAT) to complete place-and-route timing closure on their chips,” said Ausdia president and CEO Sam Appleton. “We're introducing FlatChecker to enable the acceleration and verification of ETM-based timing flows, as well as automatically generate SDC timing constraints for ETM flows from the standard flat STA signoff.”
Timevision is a comprehensive timing constraints development, verification and management solution that complements all implementation and timing signoff flows. It has the capacity to handle over 1 billion cells and thousands of clocks. Timevision integrates with all aspects of the design flow and is used before synthesis, before DFT insertion, before place and route, and when signoff timing is being run. Timevision helps designers create good SDC/TCL constraints and is a verification platform for existing timing constraints.
Ausdia is highlighting Timevision and all add-on solutions in booth # 333 at the Design Automation Conference ( DAC) at the Las Vegas Convention Center, Las Vegas, NV from June 3 - 6, 2019.
