until you understand how exactly this expansion of replicated logic works, do not use for loops. Instead think about how you want your code to behave and figure out a way to write it in C without using a for loop, then write your code in VHDL or Verilog. Below is an example of this...
Here is a simple example that illustrates the usage of a for loop. modulemy_design;integeri;initialbegin// Note that ++ operator does not exist in Verilog !for(i=0;i<10;i=i+1)begin$display("Current loop#%0d ",i);endendendmodule Simulation Log ncsim> run Current loop#0 Current loop...
Hi, When I use the normal for loop in verilog with the loop variable declared as a wire I get the following error 'i' is an invalid type in Generate loop...
I'm a beginner for verilog design. I have a question. Is there any way that could express a case statement in for loop including default part? I tried the code below. /// (reg [2:0] ctrl) for(i=0 ; i<5; i=i\+1) begin case(ctrl) i : begin out <= i; end endcase end...
I have been attempting to convert some code I have written from VHDL to Verilog without much success. My main stumbling block is the for loops in my VHDL code. My FOR loops have a much larger index, I am using 0 to 1 for simplicity. Simplified VHDL example: PROCESS(CLK) BEGIN IF...
A for loop in SystemVerilog repeats a given set of statements multiple times until the given expression is not satisfied. Like all other procedural blocks, the for loop requires multiple statements within it to be enclosed by begin and end keywords. Syn
