Hi folks Today I went through the multiple choice entry exam for the member access card for the clean room. We'll see in a few days whether I've passed or whether I need to write the exam again. I'll notify you as soon as I've got news on that front. Cheers David

Standardized Data Structures Lef/Def routines
by p4w5 12 May '18

12 May '18

Hej everybody! Sorry for not joining mumble sessions, I feel a little of on communications, but anyway, hope my question finds some positive echo ;) As I tried to understand project structures of the whole design flow - correct me if I am wrong - each part of the program uses its own file formats or parsers as data structures for macros and layers, from what I skimmed: * Graywolf uses a YACC parser for some file formats (don't know which) * in the qflow repo is some form of lefdef parser using YACC, where I am not sure if it is just for some UI stuff or supposed to be a actual parser * in qroute 20% of the LOCs are for lefdef parsing with a hand written parser I am not sure if there are some more forms of lefdef readers? So my general plan would be to write a more generic router (being more algorithmic agnostic providing a general data structure, to experiment with some routing algorithms, splitting in global and detailed routing and so on). Before dealing with this I would opt to have some common core dealing with lefdef reading and writing. Is there maybe already some tool doing this? In the last week I started going through the lefdef ref manual 5.8 and to manually parse lef files into some c++ structs, see[1] to have a look yourself. From quite some big lef files it already can parse >90% the mayor chunck. Being quite uncommented and not tougth through to much, but before wasting more time on this I wanted to get some feedback. Is the general lefdef-lib thing a idea worth spending more energy on? Is there already another attempt to do so in progress? Thanks for information and feedback! P.S. Is there already something up for the hackathon? Would be definitely up for it ;) Paul [1] https://github.com/paulwuertz/siliconverter

4 pole probe
by David Lanzendörfer 11 May '18

11 May '18

Hi Hagen The analyzer in the lab is a the Keysight b1500a (Agilent). The probes are being placed manually by hand using a microscope. The probes are "4 Micropositioners in S-926 series" with a tip diameter of 4 microns. All infos here: http://www.nff.ust.hk/en/equipment-and-process/equipment-list/metrology.html Since the b1500a is an analyzer it can do basically everything we want :-) Cheers David

Lightweight PDFs

08 May '18

Hi everyone I've now split up the one big 20 MB PDF in smaller subdocuments. The documents now load much much faster: https://github.com/leviathanch/libresiliconprocess/blob/master/process_step… @Hagen: I've finished hacking your test structure cross sections for the ESD circuit into LaTeX. (Schematics will follow, I was busy also with getting the issues fixed Mohamed reported) https://github.com/leviathanch/libresiliconprocess/blob/master/process_test… Maybe you wanna hack some text into the LaTeX files under the tikz graphics? Cheers David
