Package Modelica.Electrical.Digital.DelayDelay blocks
Package Modelica.Electrical.Digital.Delay
The Delay package collects the delay blocks which are used in many components. Both transport and inertial delay are offered for scalar connectors. The most advanced component is the sensitive inertial delay the delay time of which is chosen in dependency of the signal values. This component is also available for vector valued input.
Extends from Modelica.Icons.Package (Icon for standard packages).
| Name | Description |
|---|---|
DelayParams | Definition of delay parameters |
InertialDelay | Inertial delay with initial parameter |
InertialDelaySensitive | Provide the input as output if it holds its value for a specific amount of time |
InertialDelaySensitiveVector | Delay of a vector of digital signals |
TransportDelay | Transport delay with initial parameter |
Partial Block Modelica.Electrical.Digital.Delay.DelayParams
DelayParams is a partial model for providing delay times and inertial values. It is used in components of the package Gates which need the same parameters. The partial model does not have any behavior or equations.

Time | tLH | Rise inertial delay | |
Time | tHL | Fall inertial delay | |
Logic | y0 | L.'U' | Initial value of output |
Model Modelica.Electrical.Digital.Delay.TransportDelay
Provide the input as output exactly delayed by Tdel. If time less than Tdel the initial value initout holds.

Block Modelica.Electrical.Digital.Delay.InertialDelay
Provides the input as output delayed by delayTime if the input holds its value for a longer time than delayTime. If time is less than delayTime the initial value y0 holds.

Model Modelica.Electrical.Digital.Delay.InertialDelaySensitive
Provides the input as output delayed by Tdel if the input holds its value for a longer time than Tdel.
If the time is less than Tdel the initial value y0 holds.
The delay Tdel depends on the values of the signal change. To calculate Tdel, the DelayTable specified in
Digital.Tables is used. If the corresponding value is 1, then tLH is used, if it is -1, then tHL
is used, if it is zero, the input is not delayed.
