FIRST CLOCK FLOORPLANNING TOOL INTEGRATED WITH A HIGH ACCURACY FULL 3-D FIELD SOLVER
Santa Clara, CA - DAC, June 1999 - OEA International, Inc. announces the first release of "CLOCK Designer ", the first clock floorplanning tool which utilizes a full 3-D field solver for RCLK value extraction. CLOCK Designer is a VLSI floorplanning tool for the fast design and optimization of clock networks at the block or full chip level. CLOCK Designer works with the OEA NET-AN 3-D parasitic extraction software, which includes the "Cheetah II" 3-D Laplace/Poisson field solver technology. The program allows for design using gridded, H-tree, or Spine routing strategies. CLOCK Designer can be used to perform a wide variety of what-if scenarios to minimize skew, eliminate delay failures, estimate power and current, and optimize buffer sizes. CLOCK Designer can eliminate days of redesign time due to poor planning of clock routing.
Fast Iteration Times
CLOCK Designer allows easy modifications to the planned clock network layout. Using an
easy to modify input control file allows the user to try many alternative strategies and
trade-off driver strength with line width and spacing alternatives. Also, the optimal
driver and buffer locations can be easily determined to minimize skew and increase the
performance of the chip design.
Full Parametric Geometry Creation, 3-D Extraction, SPICE Simulation
and Feedback Loop
Using the control file and a technology file, a 3-D model of the clock network is created
including all driver/buffers and loads. An accurate RCLK SPICE sub-circuit of the
interconnect is extracted using OEA NET-AN 3-D extractor. Then, load and drivers are
added, measure statements are included and the full circuit is simulated in SPICE to
obtain delays, skew power and current consumption values. This data is then analyzed and
the results presented in a report format and also loaded into the OEA PLWS graphic
interface for color-coded viewing of the geometry and the predicted delays and skews.
Pricing, Platforms and Availability:
CLOCK Designer runs on all popular Sun and IBM workstations. Available for
Beta Site delivery with pricing information upon request.
