Apr 2, 2016 · Verilog does not support two dimensional arrays as ports of modules. This feature is supported by SystemVerilog only. In the first snippet, you are passing two dimensional array a as input, which is not supported.

Jul 11, 2016 · If you are asking how to create Verilog inputs to take that array, you could have multiple inputs, packed arrays or in some cases unpacked arrays. Multiple inputs: module aes ( input [7:0] data_1, input [7:0] data_2, //... input [7:0] data_16 ); Unpacked Array. module aes #( parameter DATA_W = 8, parameter BYTE_COUNT = 16, ) ( input [DATA_W ...

Aug 25, 2015 · SystemVerilog allows passing Multi Dimensional arrays as input to modules. You can modify the sample code and verify that fact. The command for execution of SystemVerilog code using synopsis-vcs is as follows: vcs -timescale=1ns/1ns +vcs+flush+all +warn=all -sverilog …

input [15:0] me; reg [15:0] p_array [7:0]; reg abc_pqr [2:0]; //Same as reg [0:0] abc_pqr [2:0] me is a standard 16 bit word. p_array is an 8 deep memory of 16 bit words.

You need to be using SystemVerilog to have unpacked arrays as arguments to a task. And the task as you have written it does not do the same thing as the code without the task. That is because the output array A is uninitialized and you are only setting the value indexed by x1.

Aug 8, 2005 · Verilog doesn't allow an I/O port to be a 2-D array. In Verilog 2001 you could flatten your array into a vector and pass that through the port, but that's somewhat awkward. Here is one way to do it: input [31:0] in; wire [7:0] array [0:3]; output [31:0] out; assign {array[3],array[2],array[1],array[0]} = in;

Any number of dimensions can be created by specifying an address range after the identifier name and is called a multi-dimensional array. Arrays are allowed in Verilog for reg, wire, integer and real data types. reg y1 [11:0]; // y is an scalar reg array of depth=12, each 1-bit wide.

Multidimensional Dynamic array. SystemVerilog dynamic array can be, regular array; irregular array; regular array. A regular array is a multidimensional array with member arrays of the same sizes. for example, 2-D array with the number of columns same for all the rows. In below 3 x 2 array diagram, All the 3 rows have 2 columns. SystemVerilog ...

Mar 14, 2013 · Verilog doesn't support arrays in the module port declaration. You'll need to concatenate the busses together. In the body of your code you can include a for loop to extact slices and assign them to a wire array. reg cannot be used as the type for an input.

Jul 15, 2015 · In one of my modules I use as input an array of T_ENCODED_ADDR_ADC: input T_ENCODED_ADDR_ADC [`NUM_OF_REGIONS-1:0] data_in; Then I need to pass each adc_code to a shifting unit, so I have: shifter32b shifting_unit[0:3][`NUM_OF_REGIONS-1:0](port mapping here) where in parenthesis I should map the ports.
