// Address constraints file written January 19, 2001 4:34:59 PM PST
// By FastChip Version 2.1.1 Build 001212-1646

// Overview
// --------
// The address constraints file holds constraints that govern the actions
// of the address allocator, bit stream generation, and programming of the
// system-level registers during CSoC configuration.
// 
// An address constraints file is created along with other project data
// files when your FastChip project is first created.  The newly created
// address constraints file includes default constraints appropriate for
// the project's target device.
// 
// Refer to FastChip online help for a detailed description of the address
// constraints format.
// 
// File Format
// -----------
// The address constraints file contains zero or more constraint
// statements.  Each statement begins with a keyword and ends with a
// semicolon.
// 
// Valid address constraint statements are summarized below.
// 
// All sizes and addresses can be an C-style decimal or hexadecimal
// integer, optionally suffixed with K, KB, M, MB.
// 
// The Allocate Statement
// ----------------------
// ALLOCATE START=startAddress SIZE=size ;
//  
// This statement controls the range of addresses available for automatic
// allocation. The range is in terms of the CPU native address space. You
// can only have one ALLOCATE statement
// 
// The Address Statement
// ---------------------
// ADDRESS selectorName @ address ;
// 
// This statement constrains the address allocation for a single selector.
// The address is in terms of the CPU's native address space. You can have
// at most one ADDRESS statement for each selector in your project.
// 
// The Prohibit Statement
// ----------------------
// PROHIBIT START=startAddress SIZE=size ;
// 
// This statement prevents address allocation within a certain address
// range.  You can have as many PROHIBIT statements as you want.
// Prohibited ranges can overlap each other.
