Threedelay specifications are provided depending on the gate type. There are three enumeratedparameters rise_delay, fall_delay and turnoff_delay which control the rise time, fall time andturnoff time respectively of a particular gate instance. All the delay values are user specified andshould be entered as integers. The default value for all delays is assumed to be 0. pullup andpulldown source declarations do not include the delay specifications.All the gate instances include an identifier, which is the name assigned depending upon theinstance of a particular gate. The name is useful in tracing the operation of the overall system.All primitives support the nine-value standard and do not have an option for setting the codingstyle to four-value as is provided for many of the other ModuleWare parts.HH111111232ModuleWare Reference Manual, Library Version 1.9September 18, 2008
