Always ff verilog

• What is the difference between SystemVerilog always_ff and Verilog FF?

  In fact, we use virtually the same syntax for both the SystemVerilog always_ff block and the verilog always block. The reason for this is that the behavior of the SystemVerilog always_ff block is very similar to the verilog always block. However, there are also some minor differences between these two blocks which we need to be aware of.

• What is Verilog always comb FF?

  SystemVerilog always_comb, always_ff. New and Improved. Verilog engineers will be familiar with using Verilog always to code recurring procedures like sequential logic (if not, refer to my article Verilog Always Block for RTL Modeling ), and most will have used always @ (*) to code combinational logic.

• How to include a sensitivity list in SystemVerilog always_ff?

  always_ff @ ( ) begin // Code to be executed goes here end As we can see from this, we need to include a sensitivity list when we use the SystemVerilog always_ff block. We use the same syntax to write the sensitivity list as we do when we write a normal verilog always block.

• What is a clock always statement in SystemVerilog?

  Talk about “clocked always statements”, which generate combinational logic gates and flip-flops Unfortunately, SystemVerilog does not have well-defined semantics for describing flip-flops and finite state machines (FSMs)

  example with just one “always_ff” statement (no separate “assign” statement)? • Let’s assume we still want “q” to be “1” when we are in state “S0”. • Can we put the logic for “q” instead the “always_ff” statement? • Yes, but a flip-flop will be created for “q”! Continuing with the FSM Example
