10.9 For the path in Figure 10.54, determine which latches borrow time and if any setup time violations occur. Repeat for cycle times of 1200, 1000, and 800 ps. Assume there is zero clock skew and that the latch delays are accounted for in the propagation delay
a) Δ1 = 550 ps; Δ2 = 580 ps; Δ3 = 450 ps; Δ4 = 200 ps
b) Δ1 = 300 ps; Δ2 = 600 ps; Δ3 = 400 ps; Δ4 = 550 ps
