I2C/PWM interface

This is the top module including the PWM, i2c slave [this is a prototype just to gain understaning about the big picture of the system]

NOTES

1- The PWM module is connected to the i2c slave output, but both circuits are not synchronized with each other, so far the design didn't include metastability handling

2- The PWM module divide the input fast clock by 2^8 * 2^n *k. Where n and k are given parameters during the module instantiation, and the output divided frequency is the PWM freq.

3- The PWM module uses 8-bit resolution

The module testbench

First three I2cPWM interfaces are connected to an I2C bus, with a master setting each one duty cycle

Each one of them is given an address

Then the tb master starts setting each one duty cycle by sending 8-bit on the i2c bus

This is the waveform results

System big picture from my point of view
