I want to know 2011-01-24 2020-05-23 So now, if we look at the case where the reset is not a member of the sensitivity list. You are correct in saying that this will no longer be sensitive to changes in the reset but the process is still going to execute the logic inside its block on every clock event, the clock is still in the sensitivity list. In the both the VHDL and Verilog code above, input_1 and input_2 are in what is called a sensitivity list. The sensitivity list is a list of all of the signals that will cause the Process/Always Block to execute. In the example above, a change on either input_1 or input_2 will cause the Process/Always Block to execute. Clocked processes with synchronized reset only have the clock signal on the sensitivity list; The if rising_edge(Clk) ensures that the process only wakes up on rising edges of the clock; In a synchronous design, stuff only happens at active the clock edge; Take the Basic VHDL Quiz – … Using Process Statements (VHDL) To ensure that a process is combinational, its sensitivity list must contain all signals that are read in the process.

If we include a sensitivity list in our process, our VHDL code waits at the end of the block until there is an event on one of the signals in this list. The sensitivity list in VHDL has no effect for synthesis. The synthesized function is fully specified by the body.

In VHDL 2008 you can use the keyword "all" in the sensitivity list. This will cause all signals that are evaluated in the process to automatically be added to the sensitivity list.

The sensitivity list is equivalent to the wait The rules Josh gives are good, but above all, read the warnings your tools give you and act on them. They normally check that the sensitivity list is correct and will flag any problems.

A sensitivity list contains the signals that cause the Process Statements to execute if their values change. Note: You can use Process Statements to create sequential logic. The following example shows a Process Statement that counts the number of bits in signal d .

In general processes with a sensitivity list are used to describe combinational logic and clocked logic. The sensitivity list is called The sensitivity list is equivalent to the wait on statement. An event on one (or more) of the signals listed in the sensitivity list will make the process to resume. When a process has a sensitivity list, then that process will always stop executing at the end of the sequential statements, and wait on an event on one (or more) of the signals listed in the sensitivity list. VHDL-87, -93, and -2002 These versions of VHDL do not allow the reserved word all in a sensitivity list. Instead, the list of signals to which a process is sensitive must be written out explicitly.
