Design example: For the circuit, the gates have the following parameters.

 begin{array}{c|cccc} mbox{rm Gate} & C^{rm in} & C^{rm intr} & r & a hline 1,3,6 & 3 & 3 & 0.48 & 3  2,7 & 4 & 6 & 0.48 & 8  4,5  & 5 & 6 & 0.48 & 10 end{array}

The design problem is

 min_{x,T>0} : D ~:~  begin{array}[t]{l} A_i(x) le A_{rm max}, ;;  x_i ge 1, ;; i=1,ldots, n,  D ge T_i, ;; i=1,ldots, n,  T_i ge (T_j + D_i(x)), ;; i=1,ldots, n, ;; j in mbox{small FI(i)}, end{array}

where A_i(x) = a_i x_i, and the delay functions D_i are defined here.
