how to code in verilog in python

To code in Verilog in Python, you can use the myhdl library. MyHDL is a Python package that lets you write digital hardware descriptions in Python code. It then converts the code to Verilog, VHDL or other hardware description languages (HDLs).

Here's an example code of a simple Verilog circuit written in Python using MyHDL:

main.py
from myhdl import *

# Declare inputs and outputs
@block
def my_circuit(a, b, c):
    x = Signal(bool(0))
    y = Signal(bool(0))

    # Define logic
    @always_comb
    def comb_logic():
        x.next = a or b
        y.next = x and c

    # Return inputs and outputs
    return instances()
294 chars
17 lines

In this example, we are defining a simple circuit that takes three inputs (a, b, and c) and produces two outputs (x and y). The inputs and outputs are declared using the Signal function. The @always_comb decorator specifies that the following function (comb_logic) should be executed whenever any of the inputs change. The circuit logic is defined by the comb_logic function.

Finally, the instances function returns the inputs and outputs, allowing the circuit to be used in a larger design.

To convert this code to Verilog, you simply run the following command:

main.py
to_verilog(my_circuit)

2 lines

The resulting Verilog code will be output to the console or a file, depending on how you choose to specify the output location.

MyHDL can be a very powerful tool for digital design, and the fact that you can write in Python makes it accessible to a wider audience of programmers.
