- 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

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 ?
- What is the difference between UTC and GMT? - Stack Overflow
