VIP Smartsearch

X
  • VIP Smartsearch is a framework that supports search within VIP reference documents using query in natural language. It facilitates reordering of search results and keeps record of user’s decision for the ordering of result display and applies that in search of same query on subsequent usage.

Member Function Documentation

  function void
 svt_dti_slave::build_phase
 (  uvm_phase phase  ) 

Build Phase Constructs the common class
 Superseded functions 
 uvm_component :: build_phase 
 svt_driver :: build_phase 

  function bit
 svt_dti_slave::detect_initial_reset
 (  bit mode = 0  ) 

API to get the initial reset state of the VIP

  function void
 svt_dti_slave::end_of_elaboration_phase
 (  uvm_phase phase  ) 

End of Elaboration Phase Disables automatic item recording if the feature is available
 Superseded functions 
 uvm_component :: end_of_elaboration_phase 

  function svt_dti_transaction
 svt_dti_slave::get_device_param
 (   ) 

This method returns current value of DTI device parameters via svt_dti_transaction object.

  function bit
 svt_dti_slave::get_ids_used_by_active_slave_transactions
 (  output bit [SVT_DTI_MAX_ID_WIDTH-1:0] id_list [$], input string mode , input int rw_type , input bit use_min_width , input bit silent  ) 

This method is used to get list of all IDs which are currently under use by outstanding transactions. However, user can choose the type of outstanding transactions this method should consider while extracting ID of active transactions. "mode" and "rw_type" arguments should be used for this purpose.

It returns '1' if total number of unique IDs currently used by active transactions, is less than all possible ID that can be used by an DTI transaction. This helps in determining whether randomizing ID field of a new transaction which should not be part of the all the IDs currently in use, is possible or not.

mode - Type of outstanding transactions this method should consider while extracting ID of active transactions. Currently it supports following modes (defined as string) ::

  • "all_request" => all transactions (default)

rw_type - Indicates which channel id width should be considered.

  • ' 0 ' => only read channel id width and transactions should be used
  • ' 1 ' => only write channel id width and transactions should be used
  • '-1 ' => common or either of read or write channel id width and transactions are used

use_min_width - If set to '1', minimum of read and write channel id width should be used otherwise mdtimum. This is applicable only if "rw_type == -1" i.e. no particular channel id width is specified.

silent - Suppresses debug messages from this method if set to '1'

  function int
 svt_dti_slave::get_number_of_outstanding_transactions
 (  bit silent = 1  ) 

Returns the number of outstanding transactions

 virtual function uvm_object_wrapper
 svt_dti_slave::get_object_type
 (   ) 

 Superseded functions 
 uvm_object :: get_object_type 

  function int
 svt_dti_slave::get_outstanding_slave_transactions
 (  string mode , string msg_typ = "", bit silent = 1, output svt_dti_transaction actvQ [$]  ) 

This method returns list of transactions which are currently active and pending inside slave agent.

silent - Suppresses debug messages from this method if set to '1'. Default value is '1'.

 static function type_id
 svt_dti_slave::get_type
 (   ) 

 Superseded functions 
 uvm_object :: get_type 

 virtual function string
 svt_dti_slave::get_type_name
 (   ) 

 Superseded functions 
 uvm_object :: get_type_name 
 uvm_component :: get_type_name 
 uvm_driver :: get_type_name 

  function void
 svt_dti_slave::new
 (  string name , uvm_component parent  ) 

CONSTRUCTOR: Create a new driver instance

name - The name of this instance. Used to construct the hierarchy.

parent - The component that contains this intance. Used to construct the hierarchy.

 Superseded functions 
 uvm_component :: new 
 uvm_driver :: new 

  task
 svt_dti_slave::read_reg
 (  bit [SVT_DTI_MAX_ADDR_WIDTH-1:0] tagged_addr , output bit [7:0] read_data []  ) 

This method reads register located at the specified address and returns its content.

tagged_addr - Address of the register being read. This must be tagged address i.e. it needs to differentiate between secure and non-secure addresses. 'secure_access' attribute is appended at the MSB of address considering 'addr_width' as effective address width.

read_data - Holds value of the register content returned by reading the register.

  function void
 svt_dti_slave::reconfigure
 (  svt_configuration cfg  ) 

Called when a new configuration is applied to the VIP
 Superseded functions 
 svt_driver :: reconfigure 

  function void
 svt_dti_slave::report_phase
 (  uvm_phase phase  ) 

Report phase execution of the UVM component
 Superseded functions 
 uvm_component :: report_phase 

  task
 svt_dti_slave::run_phase
 (  uvm_phase phase  ) 

Run phase Starts persistent threads like consume_from_seq_item_port()
 Superseded tasks 
 uvm_component :: run_phase 
 svt_driver :: run_phase 

  function void
 svt_dti_slave::set_object_id
 (  svt_dti_transaction xact  ) 

  task
 svt_dti_slave::wait_for_out_of_reset
 (  int mode = 0  ) 

waits until slave is out of reset state

mode - if set to '1' then it waits for 1 clock cycle after reset is detected deasserted. otherwise, it waits for reset to be sampled as deasserted and comes out of reset after waiting for the negedge of the same sampling clock that detected reset de-assertion to avoid any race condition.
