Verilog-2001 vs SystemVerilog
Verilog-2001 is widely synthesizable; SystemVerilog adds stronger typing, interfaces, assertions and verification constructs, but tool support varies.
Use a small synthesizable subset deliberately. For teaching and portable examples, Verilog-2001 plus explicit testbenches is still useful. For larger teams, SystemVerilog types, packages and assertions can reduce errors when the selected tools support them.
