Class uvm_resource_base
Name |

---|---|---|
access |

precedence |
int unsigned |
This variable is used to associate a precedence that a resource has with respect to other resources which match the same scope and name. Resources are set to the default_precedence initially, and may be set to a higher or lower precedence as desired. |
default_precedence |
int unsigned |
The default precedence for an resource that has been created. When two resources have the same precedence, the first resource found has precedence. |
Constructors
- function new ( string name, string s ) [source]
constructor for uvm_resource_base. The constructor takes two arguments, the name of the resource and a regular expression which represents the set of scopes over which this resource is visible.
Functions
- virtual function uvm_resource_base get_type_handle ( ) [source]
Pure virtual function that returns the type handle of the resource container.
- function void set_read_only ( ) [source]
Establishes this resource as a read-only resource. An attempt to call uvm_resource#(T)::write on the resource will cause an error.
- function void set_read_write ( ) [source]
Implementation question
Not sure if this function is necessary.
Once a resource is set to read_only no one should be able to change that. If anyone can flip the read_only bit then the resource is not truly read_only.
- function bit is_read_only ( ) [source]
Returns one if this resource has been set to read-only, zero otherwise
- function void set_scope ( string s ) [source]
Set the value of the regular expression that identifies the set of scopes over which this resource is visible. If the supplied argument is a glob it will be converted to a regular expression before it is stored.
- function string get_scope ( ) [source]
Retrieve the regular expression string that identifies the set of scopes over which this resource is visible.
- function bit match_scope ( string s ) [source]
Using the regular expression facility, determine if this resource is visible in a scope. Return one if it is, zero otherwise.
- virtual function void set_priority ( uvm_resource_types::priority_e pri ) [source]
Function
set priority
Change the search priority of the resource based on the value of the priority enum argument.
- virtual function string convert2string ( ) [source]
function convert2string
Create a string representation of the resource value. By default we don't know how to do this so we just return a "?". Resource specializations are expected to override this function to produce a proper string representation of the resource value.
- virtual function void do_print ( uvm_printer printer ) [source]
Implementation of do_print which is called by print().
- function void record_read_access ( uvm_object accessor ) [source]
- function void record_write_access ( uvm_object accessor ) [source]
- function void init_access_record ( uvm_resource_types::access_t access_record ) [source]
Initialize a new access record
Tasks
- function wait_modified ( ) [source]
This task blocks until the resource has been modified -- that is, a uvm_resource#(T)::write operation has been performed. When a uvm_resource#(T)::write is performed the modified bit is set which releases the block. Wait_modified() then clears the modified bit so it can be called repeatedly.
Non-parameterized base class for resources. Supports interfaces for scope matching, and virtual functions for printing the resource and for printing the accessor list
