- 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
- 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?
- 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
- 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
- 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
- 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 - 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
