SAGE Data Sheet


SAGE addresses problems associated with complex processes involving large amounts of data, many files, and many tools in IC hardware development. Often there are dozens of steps, executed over many iterations, on a large collection of evolving data files. Even in the hands of a seasoned expert, these task flows are error prone.

Add to that the real-life dynamics of flows in which unexpected problems occur and workarounds involving new tools or scripts are inserted into the allegedly "golden" flow that worked last time, assuming anyone really knows what that was!

SAGE conceptually categorizes these types of problems into five areas:
·         Data Integrity
·         Flow Standardization
·         Flow Integrity
·         Flow Management
·         Project Tracking
First, there is the integrity of the data. Was the correct version of each file used in the process, or did some out-of-date or stray creep in to the process?  What records were kept to prove this?

Next, how do you capture the expert knowledge that went into the development of the flow in an understandable format? Not everyone is an expert, and maybe he left last week. We call this problem flow standardization. This includes the details about invoking tools. What are the specific commands and command-line arguments? What environment variables are necessary for a tool? This is known as tool encapsulation.

Given that the correct data are used, were all the steps performed correctly so far? Were the right tools used at the right time? And what step is next? We call this flow integrity.

Once there is a golden flow that everyone understands, what happens when it tarnishes? Some bug in some tool crops up that requires a complicated workaround. Or perhaps a new tool needs to be added that replaces or supplements the old flow. Often an expert (you hope) gets in and tackles this, weaving a bunch of scripts together. Now that that's done, how do you capture it, maintain it, and deploy it elsewhere? This is the problem of flow management.

Finally, given a flow and all the tools and files involved in your complex project, how can you tell where you're right now? What jobs ran? Which ones failed or passed? Where are the reports associated with that step in the flow? This all comes under the heading of project tracking.

SAGE tackles these problems using a rich set of features and standards. For rapid startup deployment, SAGE has standard directory structures for tools, libraries, and projects. These can also be customized to accommodate existing infrastructures.

For data integrity, SAGE manages the location and status of the tools, files, and scripts in the flow. SAGE understands their logical dependencies, knowing whether they're up-to-date not. In this sense, SAGE acts like UNIX make.

Keeping track of all the pieces of a flow is a difficult task. Usually, this is done on paper, after the fact, and with varying amounts of accuracy. SAGE provides a living, working vision of the flow, down to the lowest level of detail. The SAGE model of a flow is a working standard that can be understood and re-used.

For flow integrity, SAGE maintains a database identifying the exact tools used, when they were used, and what the results were.  At any given time, SAGE tracks what tasks are ready to perform next.

As a flow evolves new steps are added, some are deleted, and file and tool locations may change. SAGE includes a flow editor, providing the means to adapt flows, capture them, and implement them.

SAGE controls the operation of the flow by launching jobs, sequentially or in parallel, waiting for previous steps to complete or for the required prerequisites to be met. SAGE can run jobs locally, or distribute them using any job queuing system.

Given this detailed knowledge about the flow, SAGE is in a position to provide up-to-the-minute job status for each file tracked by SAGE. The metrics and reports collected at then end of each job reflecting the success or failure of the job as well as the tool-specific results are available for display. SAGE keeps track of the tool log files and provides an environment for summarizing them at any time.

SAGE comprises these major elements:



SAGEStandards Standard directory structure organization
SAGEFlow A tool for managing complex development flows
SAGEBatch SAGE interface for managing compute job submissions
SAGERevise SAGE interface to revision control tools
SAGEBuild An enhanced make tool
SAGE Project Tracking Standards for gathering and presenting project status


Engineers and Programmers

SAGE provides benefits to engineers and programmers by providing a homogeneous system to handle workflow processes that include various tools, files, dependencies, and status. It supplies the convenience of UNIX make in a clear, easy to understand GUI. It also provides easy access to remote or local job submission and the status of the jobs at a glance. The job history database contains a history of the creation of designated targets. This history includes the status of the target and the CPU time spent making it.

CAD Engineers

For CAD engineers, SAGE provides a flexible, extensible environment for developing, documenting, and maintaining standard process flows for any development project.


SAGE provides the engineering manager quick and visual access to the status of a given project in terms of the deliverable file objects in the flow.  SAGE can collect and summarize a variety of custom metrics.
