Formal tuning animations!

This key will help explain what you see:

• The Z axis is delay, the arcs are "delays" through individual gates.
• The horizontal "planks" are arrival times.
• The critical paths are colored RED, non-critical paths are GREEN.
• The width of each arc represents the size of the gate.
• The curvature of each arc represents the local sensitivity of the delay to transistors sizes.
• The X-Y locations of the arcs are chosen simply by sorting each gate by its depth in the graph so that the timing of the circuit is represented by a series of steps to be climbed. The most critical delays are nearest to the viewer.

Now for the animations:

• inv3 animation
• c17 animation
• a3_3 animation
• full_adder animation
• iqia_mac animation
• alu1b_pcell_flat animation
• iqia_mac animation with and without pruning side-by-side
