Globals

Simulation Control
run_test	Convenience function for uvm_top.run_test().
Reporting
uvm_report_enabled	Returns 1 if the configured verbosity in uvm_top is greater than verbosity and the action associated with the given severity and id is not UVM_NO_ACTION, else returns 0.
uvm_report_info
uvm_report_warning
uvm_report_error
uvm_report_fatal	These methods, defined in package scope, are convenience functions that delegate to the corresponding component methods in uvm_top.
Configuration
set_config_int	This is the global version of set_config_int in uvm_component.
set_config_object	This is the global version of set_config_object in uvm_component.
set_config_string	This is the global version of set_config_string in uvm_component.
Miscellaneous
uvm_is_match	Returns 1 if the two strings match, 0 otherwise.
uvm_string_to_bits	Converts an input string to its bit-vector equivalent.
uvm_bits_to_string	Converts an input bit-vector to its string equivalent.
uvm_wait_for_nba_region	Callers of this task will not return until the NBA region, thus allowing other processes any number of delta cycles (#0) to settle out before continuing.
uvm_split_string	Returns a queue of strings, values, that is the result of the str split based on the sep.

run_test

task run_test ( string test_name = "" )

Convenience function for uvm_top.run_test(). See uvm_root for more information.

uvm_report_enabled

function bit uvm_report_enabled ( int verbosity,
uvm_severity severity = UVM_INFO,
string id = "" )

Returns 1 if the configured verbosity in uvm_top is greater than verbosity and the action associated with the given severity and id is not UVM_NO_ACTION, else returns 0.

Static methods of an extension of uvm_report_object, e.g. uvm_compoent-based objects, can not call uvm_report_enabled because the call will resolve to the uvm_report_object::uvm_report_enabled, which is non-static. Static methods can not call non-static methods of the same class.

uvm_report_info

function void uvm_report_info( string id,
string message,
int verbosity = UVM_MEDIUM,
string filename = "",
int line = 0 )

uvm_report_warning

function void uvm_report_warning( string id,
string message,
int verbosity = UVM_MEDIUM,
string filename = "",
int line = 0 )

uvm_report_error

function void uvm_report_error( string id,
string message,
int verbosity = UVM_LOW,
string filename = "",
int line = 0 )

uvm_report_fatal

function void uvm_report_fatal( string id,
string message,
int verbosity = UVM_NONE,
string filename = "",
int line = 0 )

These methods, defined in package scope, are convenience functions that delegate to the corresponding component methods in uvm_top. They can be used in module-based code to use the same reporting mechanism as class-based components. See uvm_report_object for details on the reporting mechanism.

Note: Verbosity is ignored for warnings, errors, and fatals to ensure users do not inadvertently filter them out. It remains in the methods for backward compatibility.

Configuration

set_config_int

function void set_config_int ( string inst_name,
string field_name,
uvm_bitstream_t value )

This is the global version of set_config_int in uvm_component. This function places the configuration setting for an integral field in a global override table, which has highest precedence over any component-level setting. See uvm_component::set_config_int for details on setting configuration.

set_config_object

function void set_config_object ( string inst_name,
string field_name,
uvm_object value,
bit clone = 1 )

This is the global version of set_config_object in uvm_component. This function places the configuration setting for an object field in a global override table, which has highest precedence over any component-level setting. See uvm_component::set_config_object for details on setting configuration.

set_config_string

function void set_config_string ( string inst_name,
string field_name,
string value )

This is the global version of set_config_string in uvm_component. This function places the configuration setting for an string field in a global override table, which has highest precedence over any component-level setting. See uvm_component::set_config_string for details on setting configuration.

Miscellaneous

uvm_is_match

function bit uvm_is_match ( string expr,
string str )

Returns 1 if the two strings match, 0 otherwise.

The first string, expr, is a string that may contain ‘*’ and ‘?’ characters. A * matches zero or more characters, and ? matches any single character. The 2nd argument, str, is the string begin matched against. It must not contain any wildcards.

uvm_string_to_bits

function logic[UVM_LARGE_STRING:0] uvm_string_to_bits( string str )

Converts an input string to its bit-vector equivalent. Max bit-vector length is approximately 14000 characters.

uvm_bits_to_string

function string uvm_bits_to_string( logic [UVM_LARGE_STRING:0] str )

Converts an input bit-vector to its string equivalent. Max bit-vector length is approximately 14000 characters.

uvm_wait_for_nba_region

task uvm_wait_for_nba_region

Callers of this task will not return until the NBA region, thus allowing other processes any number of delta cycles (#0) to settle out before continuing. See uvm_sequencer_base::wait_for_sequences for example usage.

uvm_split_string

function automatic void uvm_split_string ( string str,
byte sep,
ref string values[$] )

Returns a queue of strings, values, that is the result of the str split based on the sep. For example:

uvm_split_string("1,on,false", ",", splits);

Results in the ‘splits’ queue containing the three elements: 1, on and false.
