I m trying to verify my DUT that contaning a I2C master and i use I2C\_VCC as slave but i have this error  
Can you help me  
Thanks  
the error:

The test sequencer:

```
await_uvvm_initialization(VOID);
start_clock(CLOCK_GENERATOR_VVCT, 1, "Start clock generator");
log(ID_LOG_HDR, "Starting simulation of TB for counter using VVCs", C_SCOPE);
------------------------------------------------------------
log("Wait 10 clock period for reset to be turned off");
wait for (10 * C_CLK_PERIOD); -- for reset to be turned off

```

I2C\_SLAVE\_TRANSMIT(I2C\_VVCT,1, x"55", “sendind data frome vvc master to slave DUT”);  
await\_completion(I2C\_VVCT,1, 1000 \* C\_CLK\_PERIOD);

This seems that your not addressing the VVC.

Check the ID of the I2C\_SLAVE VVC in your test harness.  
From your code

`I2C_SLAVE_TRANSMIT(I2C_VVCT,1 <=====================,....`

I can only see that you are addressing VVC “1”, so make sure that in the th it is also “1”.  
if it is a different number then a timeout will occur

thanks for your response, i re-check i make the good instance in Test harness end test sequencer,

I changed the VVC , i have the same problem,  
Test harness

and the simulation is stopped in this procces in methods\_pkg file

Use for all your VVC’s a unique number.

In the test harness I have them as generics

```auto
th
GENERIC (
constant C_GPIO_ID_VVC = 1000;
constant C_CLK_ID_VVC = 2000;
constant C_I2C_ID_VVC = 3000;
)
port 
(
...
)

```

I create the numbers in the TB:

```auto
constant C_GPIO_ID_VVC = 1;
constant C_CLK_ID_VVC = 2;
constant C_I2C_ID_VVC = 3;

```

And I pass them on to the test harness

```auto
i_th : work.testharness
generic map
(
C_GPIO_ID_VVC => C_GPIO_ID_VVC,
C_CLK_ID_VVC => C_CLK_ID_VVC,
C_I2C_ID_VVC => C_I2C_ID_VVC

```

…

And then use them in your functions

`gpio_set(GPIO_VVCT, C_GPIO_ID_VVC ,....`

)

i have always the same error, did i shoud set any other generic parameter in bfm\_pkg?

i remark here that no problem for CLOCK\_GENERATOR\_VVCT but there is an error for GPIO\_VVCT

Ok, good to hear.  
It is even better to declare the unique ID’s in a package and include that package in the TB and in the TH.
