AtopTech’s Aprisa, Cuts the Physical Design Time

of Sharp’s Multimillion-Gate System-on-Chip Design


SoC designers using Aprisa produced the best quality of results with very short turn-around time; used flat design methodology which will be continued on other large SoC designs


Santa Clara, CA–January 23, 2008—ATopTech, Inc. a new electronic design automation (EDA) company tackling today’s physical design challenges of integrated circuits (ICs) at 90 nanometers and below, today announced that Sharp Corporation, a major Japanese consumer electronics manufacturer, used AtopTech’s Aprisa place and route family of physical design tools to complete the tape-out of a system-on-chip for the consumer market. Using Aprisa enabled Sharp to dramatically shorten the physical design time.


Aprisa is a complete netlist-to-GDSII physical design solution that has already been used successfully in several 65nm tape outs and is currently in active use in several 40nm design efforts. Aprisa, based on AtopTech’s Interconnect Centric Precision Optimization technology, offers real design closure at 90nm and below.


On this important multi-million-gate system-on-chip (SoC) design, Sharp’s goal was to use a flat physical design methodology. Before purchasing Aprisa, the design team was using an industry-standard place and route system, but encountered run time and capacity limitations that prevented the use of a flat design methodology. As a result, Aprisa was purchased, which enabled the design to be done flat, and the design team was able to finish the high quality SoC in a short turn around time


“Aprisa is a high quality place and route solution,” said Mr. Takayoshi Tanaka, General Manager of Development Department III Electronic Components and Devices Development Group, at Sharp Corporation. “We achieved much better design results – in terms of timing, power, and area – and completed the physical design much sooner than we expected. It was gratifying to see that the flat design approach is still feasible for large SoC designs.”


“Sharp has a long history of innovation in consumer electronics, and we’re pleased that Aprisa was instrumental in the success of their new system-on-chip,” said Eddie Araki, President, ATopTech KK. “Sharp’s experience with Aprisa in achieving faster time to market, lower design costs, and a better performing product confirms the market need for our next-generation place and route product family. We look forward to a productive long term relationship with Sharp.”
