Shift Operations

Dart has implemented the triple shift operator (>>>) in the opposite way as is implemented in SystemVerilog. That is to say in Dart, >>> means logical shift right (fill with 0’s), and >> means arithmetic shift right (maintaining sign). ROHD keeps consistency with Dart’s implementation to avoid introducing confusion within Dart code you write (whether ROHD or plain Dart).

a << b    // logical shift left
a >> b    // arithmetic shift right
a >>> b   // logical shift right
