假如我有一些信号需要展开，信号的格式如下所示：
input.file
Hello/My/name/is/AAAAA[9:0] Hello/My/name/is/BBBBB[0:7] Hello/My/name/is/CCCCC[3:3] Hello/My/name/is/DDDDD展开之后的格式如下所示：
Hello/My/name/is/AAAAA[9] Hello/My/name/is/AAAAA[8] Hello/My/name/is/AAAAA[7] ~~~此处省略若干行~~~ Hello/My/name/is/CCCCC[1] Hello/My/name/is/CCCCC[0] Hello/My/name/is/CCCCC[3] Hello/My/name/is/DDDDD下面的python脚本（python2）可以实现这个功能：
expand_bus_bits.py
#!/usr/bin/python import re fh = open('./input.file') for line in fh.readlines(): # print line m = re.match(r'(.*)\[(\d+):(\d+)\]', line) if m: signal_name = m.group(1) index0 = int(m.group(2)) index1 = int(m.group(3)) # print signal_name # print index0 # print index1 # print signal_name + "[" + str(index0) + ":" + str(index1) + "]" if (index0 > index1): while (index0 >= index1): print signal_name + "[" + str(index0) + "]" index0 = index0 - 1 elif (index0 < index1): while (index0 <= index1): print signal_name + "[" + str(index1) + "]" index1 = index1 - 1 else: print signal_name + "[" + str(index0) + "]" else: print line执行的结果默认输出到屏幕上。
下面是输出的结果：
