Is 2D array synthesizable?

It depends on the synthesis tool and what you are trying to do. It is supported to be able to infer RAM structures from a 2D array with all of the synthesizers I have used before. Doing anything more exotic is probably not supported. A module with a 2D array like this will be synthesized.

Is 2D array is multidimensional?

These arrays are known as multidimensional arrays. Here, x is a two-dimensional (2d) array. The array can hold 12 elements. You can think the array as a table with 3 rows and each row has 4 columns.

Does Verilog support 2D array?

An array declaration of a net or variable can be either scalar or vector. 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.

Can arrays be multidimensional?

Multidimensional Arrays can be defined in simple words as array of arrays. Data in multidimensional arrays are stored in tabular form (in row major order).

Is array synthesizable in Verilog?

Verilog arrays are synthesizable, so you can use them in synthesizable RTL code.

Are associative arrays synthesizable?

But, the constructs which are used in the Verification Environment are non-synthesizable. They are as follows: Dynamic arrays and associative arrays.

Is 2D array and multidimensional array same?

Two – dimensional array is the simplest form of a multidimensional array. We can see a two – dimensional array as an array of one – dimensional array for easier understanding.

How do you declare a 2D array in Verilog?

For a 2D array of bytes, first check your simulator/compiler. Older versions (pre ’01, I believe) won’t support this. Then reg [7:0] a [0:3] [0:3] will give you a 2D array of bytes. A single bit can be accessed with a[2][0][7] for example.

What are multidimensional arrays?

A multi-dimensional array is an array that has more than one dimension. A 2D array is also called a matrix, or a table of rows and columns. Declaring a multi-dimensional array is similar to the one-dimensional arrays.

What is synthesizable Verilog?

Synthesizable Verilog is that subset of the language that are accepted by the synthesis tools. The non-synthesizable constructs are used only for simulation and the synthesis tool cannot handle them.
