In standard Verilog your code will only work for simulation, as you use sequenziell contructs, (task, @() outside always). Implementation Guide to the I2C Protocol Summary This document describes the main aspects of the I2C communication with Sensirion’s Liquid Flow Sensors and provides instructions on how to implement the protocol on a controller system (master) for the communication with a sensor as the I2C … Hardware is parallel and there is no such thing like a sequenziell loop or waiting on the next clockedge with @(). Journal Of Information, Knowledge And Research In Electronics And Communication 520-522. I2C verification environment architecture A).Top module This is test case which is class of system Verilog which contains instances of I2C Env, master agent and slave agent. verilog i2c implementation. In STATE3, SDA is used to send data. An Implementation of I2C Slave Interface using Verilog HDL VI. In STATE2, SDA is used to read data. In other words you need to implement a state machine. It follows the I2C specification I2C bus is used by many integrated circuits and is simple to implement. Besides using this straightforward approach, there are many I2C Verilog designs available from the internet. In this paper, the principle and the operation of I2C bus protocol will be introduced. [8] A.Sahu, R. Mishra, P.Gour, “An Implementation of I2C using VHDL for Data Surveillance”, International Journal on The focus of this paper is on implementation of Inter Integrated Circuit (I2C) protocol following slave module for no data loss. B). It's really not a big thing to design an I2C master from the scratch, just based on the Philips/NXP specification. In STATE1, SDA is used to send data. Any FPGA/ Microcontroller can communicate with I2C devices even if it has no special I2C interface. Figure 1. plementation of I2C communication protocol by considering FPGA as master, EEPROM(24C02) as slave using Verilog HDL. I know this needs to be implemented using a state machine, so I have that down. With that in mind, here is my problem: SDA is bidirectional. Implementation of I2c Bus Controller Using Verilog,” Journal of Information, Knowledge and Research in Electronics and Communication Engineering Nov 12 To Oct 13, Vol. The I2C protocol is notable for some less-than-straightforward characteristics: You don’t just connect a few IC pins together and then let the low-level hardware take over as you read from or write to the appropriate buffer, as is more or less the case with SPI (Serial Peripheral Interface) or a UART (Universal Asynchronous Receiver/Transmitter). All checkers and Simple_I2C. Conclusion And Scope The ideal I2C bus has high performance, low cost, flexibility, easy upgradability. In addition, agent should be configurable for passive/active. I2C i2c_env This is I2C component, containing Agent (master and slave). Is widely used in the field of micro electronic communication control.
