OEA International Announces NET-AN/PT, the First 3D Critical Path Solver Linked With PrimeTime For Accurate Timing Closure
Morgan Hill, CA - June 3, 2002 -
OEA today announced NET-AN/PT, an interface of the OEA NET-AN 3D
Critical Net extraction Tool with the Synopsys' PrimeTime full chip timing
analysis tool. NET-AN/PT is
the result of a joint development effort and technology OEM Agreement with
Silicon Metrics of Austin, Texas. NET-AN/PT provides an easy to use,
intuitive interface to the NET-AN 3D extraction tool.
Using this interface, gate-level designers can collect nets
associated with a set of timing paths, submit them for extraction, and
load the resulting Detailed Standard Parasitics File (DSPF) or Standard
Parasitic Exchange Format (SPEF) without leaving the PrimeTime
environment. NET-AN/PT is
implemented without changing the initial timing flow. After evaluation of timing using parasitics from a full chip
extractor, critical path failures can be verified with the more accurate
parasitics from the NET-AN 3D extractor. After ECOs to the routing, NET-AN/PT
is the only tool that allows for individual critical paths to be
re-extracted and updated in the timing database.
NET-AN/PT works with
any gate level design and can be applied to block level or full chip level
designs. Using several new
Tcl commands within the PrimeTime interface, the user can easily find
critical paths that are dominated by interconnect. The critical paths are
then submitted to the NET-AN 3D extractor and accurate parasitics are
back-annotated via DSPF or SPEF into the PrimeTime database.
The user then can recompute the path, based on the more accurate
parasitics to see if it will now pass or determine where to correct the
net. An optional full
transistor level Spice simulation of the critical path is available.
Platform Computing Corporation's Load Sharing Facility (LSF) software. If
available, NET-AN/PT queues its extraction jobs to LSF queues and
processes the results as they complete. This is the most effective means
of distributing the processing load.
OEA’s NET-AN/PT interface tool is available immediately starting at $20,000.
OEA International, Inc., is the industry leader in 3D extraction of interconnects. OEA’s tools are currently used in the most demanding extraction and design environments. Some of the world’s most advanced design facilities use OEA tools for detailed analysis and design of high-speed clocks, buses, I/O rings, and power grids.
