verilog - What does always block @ (*) means? - Stack Overflow The (*) means "build the sensitivity list for me" For example, if you had a statement a = b + c; then you'd want a to change every time either b or c changes In other words, a is "sensitive" to b c So to set this up: always @( b or c ) begin a = b + c; end But imagine you had a large always block that was sensitive to loads of signals Writing the sensitivity list would take ages In fact
Whats included in a Verilog always @* sensitivity list? So, always use "always @*" or better yet "always_comb" and forget about the concept of sensitivity lists If the item in the code is evaluated it will trigger the process Simple as that It an item is in an if else, a case, assigned to a variable, or anything else, it will be "evaluated" and thus cause the process to be triggered
Verilog Always block using (*) symbol - Stack Overflow The always @(*) syntax was added to the IEEE Verilog Std in 2001 All modern Verilog tools (simulators, synthesis, etc ) support this syntax Here is a quote from the LRM (1800-2009): An incomplete event_expression list of an event control is a common source of bugs in register transfer level (RTL) simulations The implicit event_expression, @*, is a convenient shorthand that eliminates these
jQuery ajax () using success, error and complete vs . done (), . fail . . . The point of the done() fail() always() methods is that you can Attach multiple handlers Do so anywhere and not just when calling $ ajax If you are at the $ ajax call site only attaching single handlers then those advantages don't really come into play So you can return the promise and others may attach their own handlers
verilog always, begin and end evaluation - Stack Overflow The expression always @* begin : name_of_my_combinational_logic_block code end describes combinational logic Typically the clk and rst signals are not read from inside of this type of always block, so they don't appear in the sensitivity list like wisemonkey says It is best practice to use @* for the sensitivity lists of combinational logic so that you don't forget to include a signal
verilog - Use of forever and always statements - Stack Overflow The difference between forever and always is that always can exist as a "module item", which is the name that the Verilog spec gives to constructs that may be written directly within a module, not contained within some other construct initial is also a module item always blocks are repeated, whereas initial blocks are run once at the start of
