Update User Guide Interface UVC Generation authored by Daniel Bayer's avatar Daniel Bayer
This section explains how to use the Interface UVC generation feature.
When launching the application, the Interface Verification Component Wizard opens and the following screen is what we'll see:

**Configuring the UVC Name**
The subsequent sections describe the information presented and what is mandatory and optional.
**Configuring the UVC Name (Mandatory Fields)**
In UVM, each verification component has a prefix combination that describes exactly which company, or group within a company, and the protocol are called.
This configuration is handled with the text fields "Group Name" and "Protocol Name".
Example:
Let's assume I am creating a verification component that describes an I2C protocol. In that case, I am using my name's initials and the protocol name:
Let's assume we are creating a verification component that describes a custom handshake protocol. In that case, I am using my name's initials and the protocol name:
```
Group Name Protocol Name
db i2c
db handshake
```
**Configuring the Clock Domain**
**Configuring the Clock Domain (Mandatory Fields)**
Creating the clocking details consists of three parameters:
1. Testbench Clock Name: This is the name used within the UVM testbench domain.
2. HDL Clock Name : This is the name used within the HDL top-level testbench harness
3. Clock Sensitivity : This may assume any of three values:
* Rising Edge, which means that each signal will be sampled/driven at the clock's transition from 0 to 1.
* Falling Edge, which means that each signal will be sampled/driven at the clock's transition from 1 to 0.
* Rising and Falling Edge, which indicates that whenever the clock signal transitions, then each signal's value will be sampled/driven
* Asynchronous, this means there is effectively no clock. This option should only be used in very rare cases and only if you truly understand the implications of asynchronous protocol design.
**Configuring the Reset Domain (Mandatory Fields)**
**Configuring the Reset Domain**
Creating the reset details consists of three parameters:
1. Testbench Reset Name: This is the reset name used within the UVM testbench domain.
2. HDL Reset Name : This is the reset name used within the HDL top-level testbench harness.
3. Reset-Active : This may assume any of the two values:
* Active-Low. which is used to indicate that low-level (value 0) reset is used to reset the design.
* Active-High, which is used to indicate that the high-level (value 1) reset is used to reset the design.
