uvm_reg_rdl methods

uvm_reg_rdl class methods

uvm_reg_rdl extends the uvm_reg class to add functionality for controlling test, managing interrupt tree hierarchy, and building hierarchical RTL signal names from the UVM model.

Methods:

---

function void set_rdl_tag()

Parameters:

• input string rdl_tag, (default value = "rdl_tag")

Set the rdl tag string for this register. The tag will be used to build RTL signal names using the model hierarchy.

---

function string get_rdl_name()

Parameters:

• input string prefix
• input bit add_hdl_prefix, (default value = 0)
• input string override_tag, (default value = "")

Return a string corresponding to this model element using recursive call to ancestors. Used to generate RTL signal names. RTL signal names using the model hierarchy.

---

function void set_external()

Parameters:

• input bit is_external

Set indication that this register is external to autogenerated logic.

---

function bit is_external()

Parameters:

Return 1 if this register is external to autogenerated logic.

---

virtual function void get_intr_fields()

Parameters:

• input ref uvm_reg_field fields

Return a list of all leaf fields in this register's interrupt hierarchy. This null function is overridden by child interrupt register classes.

---

virtual task get_active_intr_fields()

Parameters:

• ref uvm_reg_field fields
• input bit is_halt
• input uvm_path_e path, (default value = UVM_DEFAULT_PATH)

Return a list of all fields in this register's interrupt hierarchy that are causing halt or interrupt to be asserted. This null task is overridden by child interrupt register classes.

---

function void set_reg_test_info()

Parameters:

• input bit dont_test
• input bit dont_compare
• input int js_category

Set test related info for this register (donttest, dontcompare, js category).

---

function bit is_dont_test()

Parameters:

Return 1 if register is marked don't test.

---

function bit is_dont_compare()

Parameters:

Return 1 if register is marked don't compare.

---

function bit has_a_js_category()

Parameters:

Return 1 if register has a jspec category.

---

function bit has_js_category()

Parameters:

• input js_category_e cat

Return 1 if register has the specified jspec category.

---

function void add_js_category()

Parameters:

• input js_category_e cat

Add the specified jspec category to this register.

---

function void remove_js_category()

Parameters:

• input js_category_e cat

Remove the specified jspec category from this register.

---

virtual function void add_callbacks()

Parameters:

Null function that is overridden by block/reg classes requiring callback setup.

---

virtual function uvm_reg_block_rdl get_ancestor()

Parameters:

• input int depth

Return the uvm_reg_block_rdl element that is the specified number of ancestor levels from the current block/register.

---

function void add_def_property()

Parameters:

• input string name
• input string value

Add a user-defined property to this rdl class instance

---

function bit has_def_property()

Parameters:

• input string name

Returns 1 if a user-defined property of specified name exists for this rdl class instance

---

function string get_def_property()

Parameters:

• input string name

Returns a user-defined property of specified name for this rdl class instance

---

function string remove_def_property()

Parameters:

• input string name

Removes the user-defined property of specified name for this rdl class instance

---
