Stream Out And Stream InThe fab needs to manufacture the chip from us a description of the position of any layer. These description is stored in a file. This file is in a gds2 format. We make a stream out to create it. That the process of stream out worked correctly, we make a stream in, to compare the stream out file with the stream in file. We are making two new directories: mkdir HdAsicTutorialStreamOutmkdir HdAsicTutorialStreamIn In the CIW window we select File -> Export -> Stream... . With the library browser we go to our layout, as run directory we insert the new generated directory. The output file name is freely selectable, I prefer the same name as the schematic plus the date of the stream out (e.g. Inverter_20010412.gds2). You get a message after a successful stream out. cp HdAsicTutorialStreamOut/Inverter_20010412.gds2 HdAsicTutorialStreamIn The stream in dialog can you find under File -> Import -> Stream... . Insert the right directories and filenames and run the stream in. The Top Cell Name can you leave blank. |
