2010-09-30 Monday, Sep 18th, 2017 A module is a self-contained unit of VHDL code. Modules communicate with the outside world through the entity. Port map is the part of the module instantiation where you declare which local signals the module’s inputs and outputs shall be connected to. Port declaration format: port_name: mode data_type; The mode of a port defines the directions of the singals on that pirt, and is one of: in, out, buffer, or inout. Port Modes: An in port can be read but not updated within the module, carrying information into the module.

Let’s say it finds the value ‘ 2 ’; it adds this to the running total (initialized to zero), yielding a running total indentation of 2 spaces. Next VHDL Mode goes to buffer position 20 and asks for the current column.

The connections can be listed via positional association or via named association.

Port Mode: Identiﬁes the direction of data ﬂow through the port. The PORT statement is optional. At the top (testbench) level, none is needed. (why?) All ports must have an identiﬁed mode.
