I was designing i2c master driver for UVM. However Start condition is taken care address is being driven followed by R/w. I am not able to receive slave acknowledgement. Device address is specified as 22h so i am sending same but i am not able to receive ACK. I tried with wrong address but no NACK too. Can anyone help me what may be the reason for slave not responding ?
Thanks, Nag |

Do you have any signal traces to share? What's the I2C package doing? Have you had any success within a simulator?

Hi Nag,
Actually, it's hard to say something without the code of your I2C driver. Probably, you do not fill transaction ack/nack field before writing to the analysis port. Evgeny |
