How to lock down I/O pins in Exemplar


Problem Description:
Urgency: Standard

General Description: How do I lock down I/O pins in a VHDL file using
Exemplar's Leonardo or Galileo?


Solution 1:

Using Exemplar's Leonardo or Galileo synthesis tool, you can assign pin
locations in VHDL. The following is an example:

TYPE string_array IS ARRAY (natural RANGE<>, natural RANGE <>) OF
    character;
ATTRIBUTE pin_number : string;
ATTRIBUTE array_pin_number : string_array;
ATTRIBUTE array_pin_number OF y : signal IS ("P20", "P21", "P22",
    "P23");
ATTRIBUTE pin_number OF i : signal IS "P10";
