EDA company IC Manage has introduced its IC Manage Views storage acceleration software -a version aware, virtual file system that presents completeworkspaces views, while only transferring data on demand to a localfile cache. IC Manage Views removes network transfer bottlenecks to accelerateElectronic Design Automation (EDA) tool performance, achieveZero-Time Sync (ZTS) for workspaces, and reduce storageutilization. The tool is 100 percent compatible with all storagetechnologies and works at both local and remote sites. Zero-TimeSync a 1 gigabyte, 10,000 file workspace takes approximately onesecond to populate, allowing tools to run immediately. |
For fasterEDA tool performance, the tool uses local storage for reads, sodesign engineers get local speeds and avoid delays caused bynetwork latency. Using network storage for writes providesconsistent data storage and access. IC Manage Views automaticallyrotates least recently used files to stay within workspace cachequotas, and handles cache recovery in the event of failures orerrors. According to the company's Global Design Management survey results , the primary engineering challenges with design file managementfall into two major areas: speed and storage. The top speedproblems are network storage bottlenecks slowing the creation andupdates of remote and local workspaces, and EDA tool performance.The storage problem is that the cost of storage capacity needed tokeep up with expanding design data is too high.
Design teams areconstantly wrestling with storage needs. The survey found that onaverage, network data transfer bottlenecks account for 30 percentof the EDA tool iteration time. Numerous EDA design tools areimpacted by network bottlenecks, including place and route, RTLfunctional verification, timing analysis, SPICEsimulation/analysis, physical verification, and custom layout. Using symbolic links has been a common technique to reduce diskspace usage. However, almost three-quarters of symlinks users citemajor issues.
Approximately half cite the lack of control whenusing mirrors due to the automatic data push or out-of-syncmirrors. Other issues include workspace instability when versionsare removed from the symbolic link trees to recover space, andsecurity problems caused by difficulty managing UNIX-styledirectory permissions. IC Manage Views unloads work from a central NAS filer, therebyremoving the network bottleneck and accelerating its clientscompute jobs. Designers and verification engineers are presentedwith a fully populated view of their files. When the engineerinitiates a read operation, IC Manage Views will obtain the filefrom the local cache; if the file is not there, IC Manage Viewsfetches it from the GDP repository.
When a designer saves data, thetool will write it to local or network storage. The software has none of the limitations associated with symboliclinks described in the survey results. Designers maintain workspacefile control and stability, with fine-grained securityconfigurations independent of file system permissions. It has nohigh performance storage infrastructure requirement and no manualmanagement of network cache storage and number of versions. IC Manage Views is part of the Global Design Platform productfamily and is available immediately on Linux.
It is scheduled to bereleased on Windows before the end of 2012. This article was originally posted on EE Times Europe.
