Completion

Suggestions depend on what the cursor is inside. Type-aware ranking puts symbols from the current file ahead of the filelist, and enum literals and matching signals first on the right of an assignment.

Where	Trigger	Suggests
Module, procedural, class, covergroup body	any identifier position	Keywords valid there, plus snippets such as always_ff
Expressions	any identifier position	Visible symbols. Module names appear only where an instantiation can start
Instance ports	. inside (...)	Ports of the instantiated module not yet connected
Instance parameters	. inside #(...)	Parameters not yet assigned, with type and default
Members	. after a name	Class fields and methods, struct fields, module or interface ports and modports
Package scope	::	Members of that package only
Macros	`	Macros visible in the current file. Function-like ones insert a snippet
Includes	" after `include	.svh and .vh files from the filelist

m_fifo u_fifo (
    .i_clk(i_clk),
    .i_data(|)   // typing `.` here lists the remaining ports
);

Package members

Package members are not offered as plain identifiers just because the package is in the filelist. They appear once visible:

import uvm_pkg::*;          // every member is visible
import uvm_pkg::uvm_object; // only uvm_object is visible
uvm_pkg::                   // scope completion lists the package

Known gaps

• Typedef chains resolve one step only.
• Members of parameterized classes (my_class #(T)) are not offered.
• Hierarchical references (top.dut.signal) resolve one . hop.
• Fields of anonymous struct { ... } types are not indexed. Named typedef struct types are.
• With syntax errors in the file, keyword context falls back to plain identifiers.
