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 (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
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:
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
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
Is Java pass-by-reference or pass-by-value? - Stack Overflow 103 Java is always pass by value, not pass by reference First of all, we need to understand what pass by value and pass by reference are Pass by value means that you are making a copy in memory of the actual parameter's value that is passed in This is a copy of the contents of the actual parameter
How to keep one variable constant with other one changing with row in . . . 205 Lets say I have one cell A1, which I want to keep constant in a calculation For example, I want to calculate a value like this: =(B1+4) (A1) How do I make it so that if I drag that cell to make a calculation across cells in many rows, only the B1 value changes, while A1 always references that cell, instead of going to A2, A3, etc ?
