Which signal assignment are event triggered?
Event: Transaction (assignment) which caused the value of a signal to change.
What happens whenever a signal or variable in a sensitivity list changes?
The code inside a process is executed only when any signal in the sensitivity list changes state. For example, clock or master reset is often used in a sensitivity list. Whenever the reset or clock changes state, the code inside the process is executed.
What is sequential statement in C?
Usually, C programs are sequential in nature. Generally, sequence of statements are written in order to accomplish a specific activity. So statements are executed in the order they are specified in the program. This way of executing statements sequentially is known as Sequential control statements.
What does a sensitivity list do in VHDL?
Sensitivity lists are parameters to a process which lists all the signals that the process is sensitive to. If any of the signals change, the process will wake up, and the code within it is executed.
How are sensitivity lists used in Java programming?
Sensitivity lists are parameters to a process which lists all the signals that the process is sensitive to. If any of the signals change, the process will wake up, and the code within it is executed. We’ve already learned to use the wait on and wait until statements for waking up a process when a signal changes.
When to use sensitivity list in production modules?
You should always use a sensitivity list to trigger processes in production modules. Sensitivity lists are parameters to a process which lists all the signals that the process is sensitive to.
When must a signal be inserted into the sensitivity list of a process?
This is a common error (due to carelessness). Note that in VHDL 2008 you can use “all” keyword to automatically include all necessary signals in your process and avoid creating latches. For Synchronous Logic: Likely you only want your clock (and maybe your reset) signal in the sensitivity list.
