Below to be closed for a stable delivery of periphery implementation:

Timing violations: Currently several trials for improvement of timing and clock tree;
  - analyzing the runs and ading improvements
  - to be confirmed that the current setup timing is stable 
  - a few hold violations to be fixed

Final metal fill run: Metal density is met on a dedicated metal fill branch 
This branch does not include latest fixes of the timing violations
First merging (today) timing fixes and rerunnign with the changes needed for metal fill (new power grid)
Try tomorrow to have setup-clean and implementaiton with met density

Tempus vs Innovus signoff analysis:
  - signoff level extraction used only in tempus leading to some path violating timing in tempus only
  - adding this to innovus signoff and comparison
 
The above is required for a stable periphery implementation, currently focu on the above items only. 
Other several things eg. DRC on the RSU level that need fixes in the periphery, antennas for the inputs, etc - work done, requires review. 


Periphery Shrinkage:  

 - adapted the floorplan and the rest for this
 - did several trials, will be very challenging to shrink it by 80um
 - requires offline discussion; currently on hold??
