Design compiler pin port

  • What are the types of pins in VLSI?

    There are basically three types of pins present in the design – Input, output, INOUT..

  • What is difference between PIN and port?

    A pin is a physical connection for a single net.
    In schematics and HDLs, pin and terminal are used interchangeably to represent the the point where the connection to a network is made.
    A port is a group of pins representing a standard interface.
    In the physical world, a port is usually more than one pin..

  • What is the difference between Get_pins and Get_cells?

    get_cells: This command finds objects that represent cells (components in the netlist). get_pins: This command finds objects that represent pins (the cells' connection points)..

  • Theoretically speaking, data-to-data checks are applied between two arbitrary data signals, none of which is a clock.
    One of these is called constrained pin, which is like data pin of the flop.
    The other is called related pin, which is like clock pin of the flop.
Nov 11, 2017 port, I/Os of the subblocks are called pin. Normally I don't use get_registers command, because it's not supported by Synopsys Design Compiler 
Nov 11, 20171 Answer. I/Os of the top-level block are called port, I/Os of the subblocks are called pin. So get_ports and get_pins commands must be used
