uvm_phase_state

The set of possible states of a phase. This is an attribute of a schedule node in the graph, not of a phase, to maintain independent per-domain state

UVM_PHASE_UNINITIALIZED

The state is uninitialized. This is the default state for phases, and for nodes which have not yet been added to a schedule.

UVM_PHASE_DORMANT

The schedule is not currently operating on the phase node, however it will be scheduled at some point in the future.

UVM_PHASE_SCHEDULED

At least one immediate predecessor has completed. Scheduled phases block until all predecessors complete or until a jump is executed.

UVM_PHASE_SYNCING

All predecessors complete, checking that all synced phases (e.g. across domains) are at or beyond this point

UVM_PHASE_STARTED

phase ready to execute, running phase_started() callback

UVM_PHASE_EXECUTING

An executing phase is one where the phase callbacks are being executed. Its process is tracked by the phaser.

UVM_PHASE_READY_TO_END

no objections remain in this phase or in any predecessors of its successors or in any sync'd phases. This state indicates an opportunity for any phase that needs extra
time for a clean exit to raise an objection, thereby causing a return to UVM_PHASE_EXECUTING. If no objection is raised, state will transition to UVM_PHASE_ENDED after a delta cycle. (An example of predecessors of successors: The successor to phase 'run' is 'extract', whose predecessors are 'run' and 'post_shutdown'. Therefore, 'run' will go to this state when both its objections and those of 'post_shutdown' are all dropped.

UVM_PHASE_ENDED

phase completed execution, now running phase_ended() callback

UVM_PHASE_JUMPING

all processes related to phase are being killed and all predecessors are forced into the DONE state.

UVM_PHASE_CLEANUP

all processes related to phase are being killed

UVM_PHASE_DONE

A phase is done after it terminated execution. Becoming done may enable a waiting successor phase to execute.

The state transitions occur as follows:

UNINITIALIZED -> DORMANT -> SCHED -> SYNC -> START -> EXEC -> READY -> END -+-> CLEAN -> DONE
                    ^                                                       |
                    |                      <-- jump_to                      |
                    +-------------------------------------------- JUMPING< -+

• UVM_PHASE_UNINITIALIZED = 0
• UVM_PHASE_DORMANT = 1
• UVM_PHASE_SCHEDULED = 2

uvm_phase_type

This is an attribute of a uvm_phase object which defines the phase type.

UVM_PHASE_IMP

The phase object is used to traverse the component hierarchy and call the component phase method as well as the phase_started and phase_ended callbacks. These nodes are created by the phase macros, uvm_builtin_task_phase, uvm_builtin_topdown_phase, and uvm_builtin_bottomupphase. These nodes represent the phase type, i.e. uvm_runphase, uvm_main_phase.

UVM_PHASE_NODE

The object represents a simple node instance in the graph. These nodes will contain a reference to their corresponding IMP object.

UVM_PHASE_SCHEDULE

The object represents a portion of the phasing graph, typically consisting of several NODE types, in series, parallel, or both.

UVM_PHASE_TERMINAL

This internal object serves as the termination NODE for a SCHEDULE phase object.

UVM_PHASE_DOMAIN

This object represents an entire graph segment that executes in parallel with the 'run' phase. Domains may define any network of NODEs and SCHEDULEs. The built-in domain, uvm , consists of a single schedule of all the run-time phases, starting with pre_reset and ending with post_shutdown .

typedef struct uvm_reg_bus_op

Struct that defines a generic bus transaction for register and memory accesses, having kind (read or write), address , data , and byte enable information.

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.
