40 * ======== Platform ========
41 * Platform support for the simArctic
42 *
43 * This module implements xdc.platform.IPlatform and defines configuration
44 * parameters that correspond to this platform's Cpu's, Board's, etc.
45 *
46 * The configuration parameters are initialized in this package's
47 * configuration script (package.cfg) and "bound" to the TCOM object
48 * model. Once they are part of the model, these parameters are
49 * queried by a program's configuration script.
50 *
51 * This particular platform has a single Cpu, and therefore, only
52 * declares a single CPU configuration object. Multi-CPU platforms
53 * would declare multiple Cpu configuration parameters (one per
54 * platform CPU).
