xilinx combinatorial loop
Thank you for the response. Yeah the statement is valid only for sequential block, but in my design, I need to build a FSM in which there is a controller and ALU. The above statement is a part of the ALU which is a combinational process (ie no clk in the sensitivity list). This process is triggered as per changes to the inputs made in different states of the Controller.
Can you suggest me some way in which I can have something like an accumulator in the ALU which will add the different values for different states of the controller. The previous value shud be retained.
