- 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 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
- Always vs forever in Verilog HDL - Stack Overflow
The always construct can be used at the module level to create a procedural block that is always triggered Typically it is followed by an event control, e g , you might write, within a module, something like: always @(posedge clk) <do stuff> always @(en or d) <do stuff> always @* <do stuff>, can also use @(*) This is the typical way to write latches, flops, etc The forever construct, in
- 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
- Gitlab CI - is there a difference between a rule with when:always to a . . .
Because, the first rule will execute when the condition is met and the alternative rule ( the one with the when: always ) will do the same thing So what is the "when: always" will change? if it will change anything at all

- Difference among always_ff, always_comb, always_latch and always
I am totally confused among these 4 terms: always_ff, always_comb, always_latch and always How and for what purpose can these be used?
- Docker - what does `docker run --restart always` actually do?
docker run --always Always restart the container regardless of the exit status When you specify always, the Docker daemon will try to restart the container indefinitely The container will also always start on daemon startup, regardless of the current state of the container I recommend you this documentation about restart-policies
