mask editor
by Martin Geisse 23 Nov '19

23 Nov '19

Hi all, in case anybody is interested in this: I started working on a mask editor that is similar in principle to Magic, but with a few notable differences: - totally different, more "Paintbrush-like" approach to its user interface - not build in C around a TCL interpreter, but written in Java and extensible by writing Java code - design is done using a "virtual" technology (in Magic terms) that is as minimal as possible, hoping to derive the actual masks from this in a mostly-automated way Current results so far look promising. I was able to draw a NAND gate, export it to Magic, export it from there to SPICE and simulate it as a circuit. Screenshots: https://github.com/MartinGeisse/chipdraw/blob/master/resource/test/nand/des… Code: https://github.com/MartinGeisse/chipdraw I'm working on the DRC only now, so the NAND from above will likely have some DRC violations I didn't notice. Greetings, Martin

Hard show stopper for tools
by Christoph Maier 17 Nov '19

>From https://en.wikipedia.org/wiki/Scheme_(programming_language): "Scheme has a diverse user base due to its compactness and elegance, but its minimalist philosophy has also caused wide divergence between practical implementations, so much that the Scheme Steering Committee calls it "the world's most unportable programming language" and "a family of dialects" rather than a single language." Any programming language is only as compact and elegant as its installation procedure on different computers and operating systems.

PAD Cells
by Hagen SANKOWSKI 06 Nov '19

06 Nov '19

Hello List! While doing some homework regarding our PAD cells, I once again looked into the MOSIC Design Rules for Scalable CMOS [0]. Out of Rule Set 10.x we get the mimimum grid for bonding pad areas with 102 micron. So my question is here, do somebody has access to bonding machines and their documentation and can provide the grid of bonding pad areas this machines usually can handle? Is this 95u/100u as I still remember? Or are this machines already in the milli-inch-measured domain, e.g. 4 mil for 101.6u? Curious, Hagen.

Help - proofreading Standard Cell Configuration File
by Hagen SANKOWSKI 06 Nov '19

06 Nov '19

Hello list! Today I wrote a template to configure the Standard Cell Library build process in a TOML file [0]. Well, I like to invite you - with obviously better english language skills than me - to proofread this work [1]. Any feedback welcome! Best Regards, Hagen.
