+====== Typical OCEAN variables used in Front-End designing ======
+\\
+__**Delta-like input current spike**__
+Use an **ipulse** current source with a trapezoidal shape
+Let ''w'' be rise time, pulse width and fall time of the current pulse (e.g. 1ns), then set i2 to
+<code>
+Qin*1.6e-19/(2*w)
+</code>
+with ''Qin'' expressed as the **number of electrons**.
+\\
+__**Equivalent Noise Charge (ENC)**__
+\\
+__**Time over threshold (ToT)**__
+Define a ''ToT'' output variable in ADE L with the usage of the ''cross()'' OCEAN function,
+<code>
+(cross(VT("/Vout_comp") 0.3 1 "falling" nil nil) - cross(VT("/Vout_comp") 0.3 1 "rising" nil nil))
+</code>
