ASAP7 -- Arizona State University 7nm "predictive" PDK | ||
The PDK has RVT, LVT and SLVT based transistors. | ||
The ASAP7 PDK currently provides 3 standard cell libraries; | ||
* Two revisions (rev 27 and rev 28) of a 7.5 track library | ||
* One revision (rev 26) of a 6 track library | ||
These libraries are mapped to each of the transistor types; | ||
* RVT -> R | ||
* LVT -> L | ||
* SLVT -> SL | ||
It also provides "4x scaled" versions of these libraries. These versions reuse | ||
the same timing information but have their sizes scaled up. | ||
The libraries provide 3 corners, | ||
* FF - fast | ||
* TT - typical | ||
* SS - slow | ||
By default if not otherwise explicitly specified the default selection will be | ||
the 7.5 track library using RVT transistors and slow corner. | ||
