In the last week, I was mainly working on the followings,

i) finished the SSTA module within clustering package
- forward breath first traverse for arrival time distribution calculation
- backward breath first traverse for required arrival time and slack 
  distribution calculation
- edge/node criticality calculation

ii) worked with Yu for ISLPED submission

iii) worked with Yu for interconnect estimation before routing error 
     distribution. And gone through a few papers on uncertainties on
     buffer insertion, high level synthesis.
