Delay is mechanism allowing introducing timing parameters to specified system.
Delays are specified in signal assignment statements. It is not allowed to specify delays in variable assignments.
Syntax:
delay_mechanism ::= transport | [ rejecttime_expression ] inertial
Types :
There are two types of delays in VHDL:
1.Inertial delay:
Inertial delay is defined using the reserved word inertial and is used to model the devices, which are inherently inertial. In practice this means, that impulses shorter than specified switching time are not transmitted.
Inertial delay specification may contain a reject clause. This clause can be used to specify the minimum impulse width that will be propagated, regardless of the switching time specified (Example 3).
If the delay mechanism is not specified then by default it is inertial.
2.Transport delay:
The transport delay is defined using the reserved word transport and is characteristic for transmission lines. New signal value is assigned with specified delay independently from the width of the impulse in waveform.
