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
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
How do I force Kubernetes to re-pull an image? - Stack Overflow Using images tagged :latest imagePullPolicy: Always is specified This is great if you want to always pull But what if you want to do it on demand: For example, if you want to use some-public-image:latest but only want to pull a newer version manually when you ask for it You can currently:
Verilog (assign in always) - Stack Overflow Always use blocking assignments for combinatorial or level-sensitive code, as well a clock assignments Always use non-blocking assignments for variables that are written on a clock edge, and read on the same clock edge in another process
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
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
