Jan 23, 2015 · To be synthesizable, the for-loop needs able to static unroll. To decide which bits reverse, use an if condition to compare the indexing value and Reverse_Count. Example: for …

May 29, 2017 · 3. Reverse the bits in a byte. Below is an easy way to reverse the order of the bits within a byte. The slice size defaults to 1 if it is not specified. The slice size is a …

Apr 3, 2019 · To perform a bit-reversal in Verilog/Systemverilog, either perform concatenation using & or use a for loop. This is the concatenation code I was referring to that uses &: Code:

Mar 19, 2020 · Use a generate for loop like this: generate for (genvar i=0; i<N; i++) assign B [i]=A [N-i-1]; endgenerate. Edit: B must be a wire or Logic, not a reg for this assign statement. If …

Jul 19, 2012 · I was wondering about the easy way to reverse bits in a bus in Verilog. Here is the code I wrote: ----- if (rev) begin . out[29:0] <= inp[0:29]; // Reverse video data buss bit order . …

Dec 9, 2021 · I am trying to invert a 64-bit variable in verilog, but for some reason only one bit is inverted. wire [63:0] bc; assign bc = 64'b0; assign notbc = ~bc; I'm expecting the output to 64 …

Dec 1, 2023 · I have a byte array like the following: bit [7:0] my_array[N]; Do you know an easy way to reverse to order of elements but on 32-bit granularity? e.g., I have N = 12 my_array[3] …

Dec 23, 2021 · Is there a way I can do this using purely streaming operator alone? The best I can do without it is this: byte_array = {<<8{ {<<32{reg_array}} }};

If your compiler isn't smart enough to do it automatically, there are two options given your ADC has bits in the opposite directions (*). You can write both registers in the same order …

If you want to reverse at the chip's top interface, this works: module m(input [31:0] a, output [31:0] b); assign b=a; endmodule // To this module m(input [0:31] a, output [31:0] b); assign b=a; …
