[SOLVED] - Bit swapping in Verilog | Forum for Electronics
Nov 7, 2006 · A time ago I came across a piece of code intended to perform a bit reversing operation ( swapping the most significant bits toward less significant bits, and vice-versa ), but it seemed that would not work, like if one would superimpose the value of the other. Is it correct ? begin . a_temp<=a[7-i]; a[7-i]<=a[i]; a[i]<=a_temp; . end.
what is the best way to exchange 2 registers in Verilog
Dec 11, 2012 · With Verilog you are describing hardware, so you exchange two register's values in a single cycle by assignment. This will infer a load path for both registers from each other's output. if (swap) begin a <= b; b <= a; end

19. Swapping (Using Non-Blocking) - EDA Playground
Non-blocking assignment (<=) is a type of assignment statement used in Verilog for modeling sequential behavior in hardware designs. It is commonly used within procedural blocks, such as always blocks, to update values of variables concurrently without immediate effect.
Frequently asked question on verilog 1 - Hardware Design and Verification
Sep 8, 2018 · Q Write a verilog code to swap contents of two registers (A and B) without any temporary register? Ans: Using a nonblocking assignment will swap the two values as shown below: always @(posedge clk) begin. A<=B; B<=A; end.

Mar 19, 2020 · From google I've found that something like the following should work: for (i=0; i<8; i=i+1) begin //reverse order. assign byte0_wire[i] = bigRegister[26-i]; end. However, this won't compile, with the error that byte0_wire must have a variable data type.
