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_axi_master::build_phase
 (  uvm_phase phase  ) 

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 Superseded functions 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

  function void
 svt_axi_master::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 Superseded functions 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 bit
 svt_axi_master::get_ids_used_by_active_master_transactions
 (  output bit [SVT_AXI_MAX_ID_WIDTH-1:0] id_list [$], output bit is_idunq , 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 AXI 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) ::

  • "non_dvm_non_barrier" => all transactions which are neither DVM nor Barrier (default)
  • "non_dvm" => all transactions which are not DVM
  • "non_barrier" => all transactions which are not Barrier
  • "dvm" => all transactions which are of DVM type
  • "barrier" => all transactions which are of Barrier type
  • "dvm_barrier" => all transactions which are either DVM or Barrier type
  • Note: if "rw_type" is set to '0' then only read channel transactions will be considered for non-dvm and non-barrier type

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 maximum. 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_axi_master::get_number_of_outstanding_master_transactions
 (  bit silent = 1  ) 

Returns the number of outstanding transactions

 virtual function uvm_object_wrapper
 svt_axi_master::get_object_type
 (   ) 

 Superseded functions 
 uvm_object :: get_object_type 

  function int
 svt_axi_master::get_outstanding_master_transactions
 (  bit silent = 1, output svt_axi_master_transaction actvQ [$]  ) 

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

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

 static function type_id
 svt_axi_master::get_type
 (   ) 

Variable that keeps count of number of DVM Syncs which are accepted and DVMCOMPLETEs are yet to be added to the queue
 Superseded functions 
 uvm_object :: get_type 

 virtual function string
 svt_axi_master::get_type_name
 (   ) 

 Superseded functions 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

  function void
 svt_axi_master::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 

  function void
 svt_axi_master::reconfigure
 (  svt_configuration cfg  ) 

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

  function void
 svt_axi_master::report_phase
 (  uvm_phase phase  ) 

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

  task
 svt_axi_master::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 

  task
 svt_axi_master::wait_for_out_of_reset
 (  int mode = 0  ) 

waits until master 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.
