//
// Design principles of a floorplan file
//
// What needs to be in the file:
// - all devices, configuration for each device
// probably multiple lines that are adding config strings
// - wires maybe separately, and/or as named connection points
// in tiles?
// - connection pairs that can be enabled/disabled
// - global flags and configuration registers
// - the static data should be optional (unused conn pairs,
// unused devices, wires)
//
// - each line should be in the global namespace, line order
// should not matter
// - file should be easily parsable with bison
// - lines should typically not exceed 80 characters
//
