Steve: Thank you for the quick reply. I do have a number of specific use cases that I can outline in this discussion.
I'll start first with the distribution and dissemination of Semiconductor Intellectual Property (SIP), both 3rd party IP and internally generated for INTRA-organizational exchange. SIP within the semiconductor supply chain is exchanged INTER-organizationally between all four of the semiconductor supply chain stakeholders. The SIP is exchanged at different phases of "maturity". "Maturity" in this context refers to the relative process distance to manufacturability, i.e. how close is the SIP to release for silicon wafer manufacturing. At the most immature level, SIP is exchanged as an ASCII file that can be "pasted" into the file system for an integrated circuit component. As the various design phases of an integrated circuit proceed to "mature" the SIP toward a manufacturable chip, the SIP undergoes multiple process transformations that result in new datasets that are generated as a result of the transforms the SIP undergoes. What the SIP provider needs to do is have a means to track the use of their SIP within the context of a multi-tenancy cloud where multiple potential customers exist that could use the company's SIP. There must be constraints to restrict how the customer is allowed to use the SIP, e.g. he/she would not be able to reintegrate ANY phase of the SIP datasets into another chip design for ANY phase of new chip development. There must be a bi-directional audit trail that would allow the SIP provider to track the multiple phases of SIP transformation through a chip workflow. Finally, when the IP has been "heardened" for manufacturing, the exchange of that final dataset, which is a graphical database of polygons representing silicon and metal layers on a silicon wafer, that IP has been embedded into that dataset. We would like to have an audit trail and tracking of that into manufacturing databases as well. This is one specific, somewhat generalized use case. The next use case would be consideration of an executable, external application from an Electronic Design Automation (EDA) ISV as "IP" that would be constrained for use within a multi-tenancy cloud WFaaS.
