Product Overview


Goals of Design Data Management

• Collaborate with team members and share design

data regardless of geographical location & time

zone

• Manage all design data from Docs to GDSII

• Control and audit access and actions

• Track changes and maintain revisions and releases

• Streamline design flow

• Tapeout accurately with confidence


Ad-Hoc SoC Design Process

Specification RTL Design Synthesis

Place & RouteVerificationAnalog Design


Issues with Ad-Hoc Processes

• Design errors

– Require very expensive re-spin

• Project delays

– Impact time to market

• Lack of control and visibility

– Decreased predictability

• CAD support nightmare

Version Control

• Text and Binary Files

– Text file versions managed as deltas

– Binary files managed compressed

– Plug in your own storage method

• Directories

– Rename and move files without losing history

– Recreate project structure at anytime

– View the same project with alternative structure

• Composite EDA Objects

– Collection of files managed as a single object

– Even list of files may change with each version

• Tags

– Recreate labeled state at anytime even if tag has been reassigned



Cell-view as a Single Composite Object

Cell-view as a Composite Object

View directory &

files are managed as

a single composite

object in SOS

•# Objects in project reduced 3-4x

•Improved performance

•Data integrity of the cell-view

•Manage composite objects from any tool

Cell-view managed as files

Cell-views such as

schematics and layout

consist of multiple

files

Release & Derivative Management

• Snapshot

– Remember exact configuration including file revs and

directory structure

• Branch

– Individual Files, Directories, or Composite Objects

• Revision search order/rule

– Ordered list of labels to determine revisions to be placed

in workarea

– Manage releases and derivates while being fully aware

of development on all branches

– Rollback to any RSO at any time


Efficient Remote Site Collaboration

• Smart Cache Server

– Caches all revisions

used at site

– Maintains use count and

scrubs unused revisions

– Updates automatically

• Express update via

audit trail

• Batch query to

minimize latency

effects


InSync – Push Technology

• Automatic updates without any wait

• Cache servers & clients can subscribe for in-sync

• Update is pushed out within seconds after change

is committed to the repository

• Clients can choose to update files or update status


Enhanced Communication

• Intuitive GUI

• Revision history in

integrated browser

• Bubble up status

• Custom attributes

• Realtime Chat

• Audit Trail


• Isolated

– Users work in their own sandbox

– Changes are not published until committed

– Update workarea to get changes

– Typical work model

• Shared

– Users work in a common shared workarea

– Changes are visible on save

– Good for small groups working closely such as

custom layout engineers

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


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


Customizability

• Full command line interface

– Invoked from any shell

• Proven C API

– Used by Mentor for integration with ICstudio

• Pre and Post Event Triggers

– Extend any DM command

• Custom defined attributes

– Maintain design metrics

• Universal DM Adaptor

– Manage data from any design tool


Management

• Workarea rollback to any time with any RSO

• Project Audit Trail

• Track and plot project metrics

• Integration with issue tracking


Interface & ‘Design Aware’ DM Adaptors



SOS Client GUI

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’.


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

Universal DM Adaptor

• Configurable rules to recognize and organize design data

– Recognize design libraries

– Recognize design objects

– Organize required design files into composite design objects

– Exclude temporary files

– Re-apply rules on check-in to recreate composite design object

• Multiple rule sets to support design data from different tools

• Rules specified by admin in client configuration file (sos.cfg)

• Soft integration with a variety of design tools

– Mentor DxDesigner, Agilent ADS, Synopsys Orion, etc.

• Result: Automated error free management of design data

from several tools

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.


Packaged with the Best Support

• Round the clock support from California & India

• Timely ‗Virtually Onsite‘ support using WebEx

Online Remote Support service

• Quick response to fixes and enhancements


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
