In the last week, I was working on the following,

i) Finished the draft of derivation for statistical time slack allocation
   considering timing and power yield

ii) Finished SPICE simulation for 15X switch considering process variations.
    Curve fitting for delay, leakage power and dynamic energy per signal
    switch have also been done. VddH, VddL and Power-gating are all tested.

iii) Read Majid's iccad04 paper, which transforms LP problem into its dual
     problem, then formulates the dual problem into a min-cost network 
     flow problem. By solving the network flow problem and finding the
     shortest path to the virtual sink for each node in the residual 
     graph, slack is optimally budgeted.

iv) Helped Yu for vpr_lp and set up experiments. Discussed with Yu for the
    heuristic which uses the sink with minimun slack instead of min function 
    which is not suitable for network flow transformation.


Todo 
i) Extend dTLC-LP to consider the mix of wire segments with different lengths

ii) Check out MOSEK and code

iii) Set up preliminary experiments

iv) Read Hai's iccad05 paper and tcad review paper
