SSI Terminology

With Xilinx being one of the fifi rst companies to release a 2.5D device, no established terminology for the details of the technology existed prior. So as a means to communicate this, several new terms were created by Xilinx to describe the differences in the 2.5D devices. Figure 13.1 shows a representation of SSI device.

• Monolithic Device : Single-die or non-SSI device

• Super Logic Region (SLR) : An active die in an SSI device construction.

• Stacked Silicon Interconnect (SSI) : The 2.5D structure utilizing multiple active

SLRs attached and connected to a passive interposer

• Interposer : A passive layer in the construction of an SSI device that serves the

purpose of power delivery, confi guration connectivity, and connectivity between

SLRs as well as connects the SLRs to the package substrate via through-silicon

vias (TSVs)

• Super Long Line (SLL) : The active signals used to connect one SLR to an adjacent SLR in an SSI device.

• Laguna : The dedicated interface to traverse from one SLR to another via an

SLL. This interface may or may not use a dedicated register.

The fifi rst thing that should be stated is that SSI devices do not require an all new design methodology. It is possible to target an SSI device using the same top-down method generally applied to monolithic devices with no difference in design entry, implementation, and validation. The thing that needs to be realized however is that ignoring the size and construction of the underlying device may lead to less optimal results and a longer design cycle.
