Incentia Timing Analysis and Constraint Management Software Adopted by Ambarella

TimeCraft and TimeCraft-CM Picked for Great Performance, Rich Features, and Proven Quality

SANTA CLARA, Calif. and SUNNYVALE, Calif. –August 29, 2006 – Incentia Design Systems, Inc., an EDA company in the timing and synthesis market, and Ambarella, Inc., a technology leader in video and image processing IC design, today announced that Ambarella has adopted Incentia’s TimeCraftTM and TimeCraft-CM as its static timing analysis and constraint management software in its nanometer design flow.

“We have adopted Incentia’s TimeCraft and TimeCraft-CM as our static timing analysis and timing constraint management software in our 90 nm design flow,” said Chan Lee, VP of VLSI at Ambarella. “TimeCraft demonstrated itself as an excellent STA tool through its rich features, great performance and quality. TimeCraft-CM provided capabilities for checking, qualifying, validating, and debugging timing constraints.”

“Incentia’s timing analysis and constraint management software continues to demonstrate its advantages and success at customer sites,” said Ihao Chen, President and CEO of Incentia. “We are pleased that our TimeCraft and TimeCraft-CM software met Ambarella’s stringent design requirements and greatly improved their productivity.”

About Incentia’s Static Timing Analyzer and Constraint Management Software

TimeCraft is a full-chip, gate-level static timing analyzer (STA) for timing sign-off. It is the fastest STA available. Its rich features, including comprehensive timing checking and reports, a built-in delay calculator, multiple supply voltage analysis, multi-task capability for multi-corner and multi-mode analysis, and advanced PLL handing, enable analysis on a large variety of design styles. TimeCraft has demonstrated unparalleled advantages in runtime and capacity that dramatically reduce total timing verification turnaround time.

TimeCraft also offers an advanced OCV feature that provides an effective solution to addressing the effects of statistical on-chip process variations. Traditional OCV uses a constant derating factor and may impose unnecessary performance penalties on nanometer designs. These penalties include reduced performance, larger die sizes, and longer design cycles. TimeCraft’s advanced OCV uses variable derating factors based on the logic level and physical location to select the optimal derating factor for each timing path. This results in fewer timing violations, which allows design teams to rapidly achieve timing closure. The native engine-based implementation approach is easy to use and delivers unparalleled performance in runtime and memory usage.

TimeCraft-CM Incentia’s Constraint Manager, TimeCraft-CM, consists of a constraint checker, a qualified SDC (Synopsys Design Constraint) writer, and a constraint debugger. The constraint checker checks constraint files for completeness, correctness, and conflicts. It also eliminates redundant constraints. The SDC writer then produces a set of optimized constraints. The constraint debugger allows designers to identify the optimal timing exceptions in complex environments on the fly. These capabilities provide an effective and easy-to-use mechanism to purify and generate qualified constraints and thus greatly shorten total constraint management and timing verification turnaround time.
