Modelica.Electrical.Digital.Delay

Information

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.

Package Content

Name	Description
DelayParams	Definition of delay parameters
TransportDelay	Transport delay with initial parameter
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

Modelica.Electrical.Digital.Delay.DelayParams

Information

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.

Parameters

Name	Description
tLH	Rise inertial delay [s]
tHL	Fall inertial delay [s]
y0	Initial value of output

Modelica.Electrical.Digital.Delay.TransportDelay

Information

Provide the input as output exactly delayed by Tdel. If time less than Tdel the initial value initout holds.

Parameters

Name	Description
delayTime	delay time [s]
y0	initial value of output

Connectors

Name	Description
y	Connector of Digital output signal

Modelica.Electrical.Digital.Delay.InertialDelay

Information

Provides the input as output delayed by Tdel if the input holds its value for a longer time than Tdel. If time is less than Tdel the initial value initout holds.

Parameters

Name	Description
delayTime	Minimum time to hold value [s]
y0	Initial value of output y

Connectors

Name	Description
x	Connector of Digital input signal
y	Connector of Digital output signal

Modelica.Electrical.Digital.Delay.InertialDelaySensitive

Information

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 initout holds.
The delay Tdel depends on the values of the signal change. To calculate Tdel, the delaymap 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.

Parameters

Name	Description
tLH	rise inertial delay [s]
tHL	fall inertial delay [s]
y0	initial value of output

Modelica.Electrical.Digital.Delay.InertialDelaySensitiveVector

Information

The delay element Inertial Delay Sensitive is applied to a vector of n signals. The parameters tLH and tHL are valid for each of the n signals.

Parameters

Name	Description
tHL	High->Low delay [s]
tLH	Low->High delay [s]
n	Data width

Connectors

x[n]
y[n]
