/**
 * Used to test the different version reader. 
 * Current EngineIRWriter and EngineIRReader test can see class EngineIRIOTest.
 * If we change the EngineIRWriter and EngineIRReader, we should do as following: 
 * 1. use current EngineIRReader to read streams from the stored old version files. 
 * 2. compare the current wrote and readed stream with result in step1.
 * 
 * Do not forget to use current EngineIRWriter to write the design to a stream, 
 * and store it to a file like ir_io_test.V1. This will be used for later versions.
