If you go down a bit more following the text, there will be a point where it starts to list the actual extracted parasitic components(resistor or cap, in this case since it was RC extraction) along with a mention of the nodes that they are connected to. This text seems to be an introductory text where it describes the original components that exist in the schematic file. This file is quite long, readable texts appear near at the beginning of the file (check that the scroll has bared been dragged down). It has limited features but browing a hex file and simple searching features are open so its enough for my purpose. Any kind of hex editor is fine, and I have used ‘Hex Editor Neo’ free version. We need to analyze this file which requires a hex editor. ![]() This file is in a remote server so the ‘layout.oa’ file was imported to my local machine via ftp. The extraction models are all saved in ‘layout.oa’ file. It’s an ongoing process, and I have much yet to accomplish.įirst, acquire the calibre model file. Even with a simple circuit, not only are the number of parasitics overwhelming, it is organized in a manner where it is impossible for the user to intuitively acknowledge where the parasitics are generated.ĭue to such difficulties, I have decided to hack into the calibre file and try to extract values and parameters of these parasitics and processed for a more user-friendly view. Looking into the parasitics extracted and saved as calibre file is immensly difficult to view.
