Hi,

I’m using the latest UVVM version at this moment, v2 20220525  
I want to use the wishbone VVC.  
And although the readme.txt says that in the doc folder the quick reference is, it’s not in the release.

Where can I find the wishbone quick reference?

Rgds,  
Eric

Hi Eric,  
The Wishbone VIP is still in beta and documentation is one of the missing parts. You can find all VVC commands in the vvc\_methods\_pkg; They are:

```auto
procedure wishbone_write(
    signal VVCT : inout t_vvc_target_record;
    constant vvc_instance_idx : in integer;
    constant addr : in unsigned;
    constant data : in std_logic_vector;
    constant msg : in string;
    constant scope : in string := C_VVC_CMD_SCOPE_DEFAULT;
    constant parent_msg_id_panel : in t_msg_id_panel := C_UNUSED_MSG_ID_PANEL -- Only intended for usage by parent HVVCs
  );

  procedure wishbone_read(
    signal VVCT : inout t_vvc_target_record;
    constant vvc_instance_idx : in integer;
    constant addr : in unsigned;
    constant data_routing : in t_data_routing;
    constant msg : in string;
    constant scope : in string := C_VVC_CMD_SCOPE_DEFAULT;
    constant parent_msg_id_panel : in t_msg_id_panel := C_UNUSED_MSG_ID_PANEL -- Only intended for usage by parent HVVCs
  );

  procedure wishbone_read(
    signal VVCT : inout t_vvc_target_record;
    constant vvc_instance_idx : in integer;
    constant addr : in unsigned;
    constant msg : in string;
    constant scope : in string := C_VVC_CMD_SCOPE_DEFAULT;
    constant parent_msg_id_panel : in t_msg_id_panel := C_UNUSED_MSG_ID_PANEL -- Only intended for usage by parent HVVCs
  );

  procedure wishbone_check(
    signal VVCT : inout t_vvc_target_record;
    constant vvc_instance_idx : in integer;
    constant addr : in unsigned;
    constant data : in std_logic_vector;
    constant msg : in string;
    constant alert_level : in t_alert_level := ERROR;
    constant scope : in string := C_VVC_CMD_SCOPE_DEFAULT;
    constant parent_msg_id_panel : in t_msg_id_panel := C_UNUSED_MSG_ID_PANEL -- Only intended for usage by parent HVVCs
  );

```
