Always Trust Your Instincts

Understanding always trustyour instincts requires examining multiple perspectives and considerations. verilog - What does always block @ (*) means? 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. Behavior difference between always_comb and always@ (*). The always @(*) block is sensitive to change of the values all the variables, that is read by always block or we can say which are at the right side inside the always block. In your example, there are no any variables used inside always block, so this always @(*) block will not work here.

Building on this, as per SV LRM, always_comb is sensitive to changes within the contents of a function, whereas always @* is ... Verilog Always block using (*) symbol - Stack Overflow. The always @(*) syntax was added to the IEEE Verilog Std in 2001. This perspective suggests that, 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 ... Additionally, 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? Building on this, 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? In this context, 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. jQuery ajax () using success, error and complete vs .done (), .fail .... Building on this, the questions: Should we change our coding as suggested below? Is there a difference between .done() & success:, .fail() & error: and .always() & complete:?

The preamble: I was putting together a jQuery.ajax call, which I have done successfully in the past too.
