  • 26. Hierarchical References & Reuse • Hierarchically partition projects for ease of management • Share IPs, PDKs, Tech Libraries, scripts, etc. across multiple projects • External objects may – Be managed by any server - local or remote – May further reference objects in other projects • Referenced objects will be appear in user workareas just like local objects • Extensive admin controls for use and access © ClioSoft, Inc. Strictly Confidential
  • 27. Security and Access Controls • Optional server side authentication – Client challenges user to provide username & password – Server authenticates using PAM • Groups – Define groups per project separate from Unix groups – Assign users to groups • Roles – Predefined roles of admin, member, guest – Define custom roles – Assign roles to users in groups • Read and Write Permissions – Assign read and write permissions per object – Admin sets default permissions for new objects • Corporate Standards – Enforce corporate standards for authentication & ACLs © ClioSoft, Inc.

Full Command Line Interface USAGE soscmd <command name>[command arguments] EXAMPLES soscmd update Update the workarea using the current revision search order. soscmd co *.v ../top.v Check out all the files with the extension '.v' in the current directory and also the file 'top.v’ in the parent dir. soscmd discardco –F ecelib/4mux8/schematic Discard the check out of cell-view 'stim.dat' ecelib/4mux8/schematic in the root directory of the workarea even if it has been modified. soscmd ci -sco -aLog="Fixed race condition." Check in ALL the checked out objects with a change log ‘Fixed race condition’. © ClioSoft, Inc. Strictly Confidential
  • 33. Design Data Management Issues • Design tools often create several files with program generated names – Examples: Schematic & Custom Layout editors • Data for each design unit may be saved in several files • Several temporary & run files are also created by the tools – Example: log, lock, backup • End users cannot easily make sense of the design data – Which files should be managed & versioned – Which files belong together – Which files should NOT be managed • Reliable data management and revision control is difficult © ClioSoft, Inc.

  • 47. Yet Simple to Administer & Use • ―SOS viaDFII is very well-integrated with the Cadence toolset. It is simple, yet complete. Even designers who have never used version control were able to pick up the basics and become productive very quickly...‖ – Brenda vanVeldhuisen, Principal Engineer Tektronix, Inc. • ―We‘re a start up and have used ClioSoft Design Management software since June, 2007. We don‘t have a dedicated CAD person. I personally installed the software and served as an administrator. The product is very easy to use. ...‖ – Eddy Huang, VP, Technology Engineering, SiliconBlue Technologies Corp. © ClioSoft, Inc. Strictly Confidential

  • 49. Customers Concur – ―Best Support‖ • ―NONE of the many other EDA vendors we deal with does support better.‖ Martin Collinge, Director of EDA, Zarlink, UK • ―I would like to say that ClioSoft provides the BEST and most timely support of any of our EDA vendors!!! Because our problems many times mean a work STOP, this is very important!!!‖ Ken Worland, CAD Engineer, Analog Devices • ―In all my years in IT (almost 20 years now) I've never received technical support from a company that is as good as what I've got from Cliosoft. You are to be commended. I've used a bunch of different revision control tools (RCS, CVS, SCCS, Subversion, Arch, VSS, SourceGear's Vault, DesignSync), and though most are open source, support for the commercial ones doesn't come close to what you provide.‖ C. R. Oldham, EDA Manager, Formerly at Intel & Marvell © ClioSoft, Inc. Strictly Confidential
