HDLBits刷题_Verilog Language_Alwaysblock1
Since digital circuits are composed of logic gates connected with wires, any circuit can be expressed as some combination of modules and assign statements. However, sometimes this is not the most convenient way to describe the circuit. Procedures (of which always blocks are one example) provide an alternative syntax for describing circuits.
For synthesizing hardware, two types of always blocks are relevant:
Combinational: always @(*)Clocked: always @(posedge clk)
