Figure 6.5: Variation (delay) estimation error vs. measurement error.

Thus, performance of the ^ɪ-regularization over the ^-minimization increases as
measurement noise increases.

The effect of the number of measurements is illustrated in Figure 6.6. The
horizontal axis is the number of delay measurements divided by the number of
the gates. Again, the -regularization performs more than two times better than
the ^-minimization. On the figure, the estimation subspace is 84 for both C432
and C880 circuits.

Next, we evaluate the basis path sets for the benchmark circuits. The method
introduced in Section 4.5.2 provides a heuristic procedure for basis path selection.
However, it does not necessarily result in an independent basis path that covers all
the space. Table 6.3 shows the number of basis paths in the benchmark circuits.
