GLOBALFOUNDRIES will describe the methodology and collateral available in the GLOBALFOUNDRIES SignOff Digital Flow. This flow comes in different variants for different technology nodes. It is silicon validated ,is a fully executable flow and is designed to be modular and to provide quick setup for customers who wish to design to GLOBALFOUNDRIES process. It addresses critical design concerns and provides detailed and accessible methodology to address the challenges. The presentation will emphasize the 28nm flow and introduce the 20m variant of the flow.
Particular attention will be paid to the Cadence based Digital flow which is derived from a Silicon validated design. The design consisted of multiple cores designed with different experiments in low power, DFM, etc.
GLOBALFOUNDRIES will describe the methodology and collateral available in the GLOBALFOUNDRIES Production AMS flow. The flow was used to design a mixed signal chip incorporating a 3Ghz PLL that was manufactured in GLOBALFOUNDRIES 28SLP process in Fab 1 in Dresden, Germany. The manufactured chip has been tested and used to validate the flow. The presentation will describe how the IP design is captured in the collateral available from GLOBALFOUNDRIES. The results of silicon testing will be presented and guidelines to successful AMS design for GLOBALFOUNDRIES process. The presentation will emphasize the 28nm design node but will also introduce the 20nm variant which will also undergo Silicon validation.
The flow itself is a mixed vendor flow, constructed as a series of Modules that provide detailed setup description for a user new to the 28nm GLOBALFOUNDRIES process. The presentation will describe the detailed documentation of the step by step design tasks; Modular and reproduceable LVS/PEX flows with all the hooks for handling Layout Dependent effects are included. Tutorial introduction to the use of GLOBALFOUNDRIES PCells is also demonstrated.
The 20nm flow addresses yet more design challenges, providing step by step instructions and guidance for designing in a double patterned environment. While the multi vendor RTL2GDSII flows from GLOBALFOUNDRIES handle coloring mostly transparent to the user, the custom flows provide more hooks for the designer to take advantage of the features available with the GLOBALFOUNDRIES PDK. The flows developed by GLOBALFOUNDRIES in collaboration with EDA partners address the challenges introduced by double patterning.
