SUNNYVALE, Calif. -- Monterey Design Systems here has announced Sonar, a physical designprototyping tool for interactive exploration and optimization of multi-million gate system-on-chip (SoC) designs.
With Sonar, the company said, logic designers can explore and analyze the impact of their design decisions on die size, clock speed, and chip floorplan at an earlier stage, without waiting for the
detailed information obtained after physical place and route. Sonar is designed to allow users to optimize chip speed and size, and make architectural decisions with an accurate analysis of the physical impact, while being confident that the design will be correctly realized in layout with
Monterey's In One Pass technology.
Sonar is used as the front-end to the company's flagship product, Dolphin. As part of a
customer's frontend design flow, Sonar is used after synthesis to determine physical implementation difficulties. Users can then interactively refine the netlist for faster layout success with Dolphin. Sonar was developed to provide logic designers with interactive capabilities that will reduce both the design time and cost of complex, deep submicron (0.25 micron and below) designs by improving productivity of their design flows.
"The ability to have a physical prototype of the final layout is like taking blinders off the eyes of front-end designers," said Jacques Benkoski, president and CEO for Monterey Design Systems. "They now can make intelligent decisions at the netlist level. Because Sonar analyzes the
effects of the physical layout data, users can optimize the design for congestion and timing and get to a production tape-out much faster."
Combined with Dolphin, Sonar provides a single environment from netlist to GDSII. The added value of Sonar is that it enables logic designers to finalize their architecture and create a true "hand-off" quality netlist, timing and floorplan for rapid and predictable completion of the physical implementation.
Fundamental design trade-offs including size, congestion and timing can be interactively optimized to produce a floorplan and netlist that allow Dolphin to achieve design closure, according to Monterey Design. Sonar and Dolphin use a shared database model that allows Sonar to analyze all physical aspects of the placement, routing and optimization of the netlist. Sonar only performs analysis to a level of detail that assures complete design closure when running Dolphin. Because of this, Sonar executes extremely fast without losing any of the detailed information to confidently reach design closure.
Monterey will also provide a Web-based version of the product, eSonar, similar to Monterey's earlier announced design portal, eDolphin (see March 9 story).
Both Sonar and eSonar will be available for general release in the third quarter. Pricing for Sonar starts at $105,000 a year for time-based licenses, while eSonar users will be able to select from the company's three new business models: global access, design portal and time-based design, that
were recently announced with eDolphin.
