Quote from: Dila Yir on July 02, 2024, 17:00:27What does "taped out" mean? It's mentioned twice, quickly, with no explanation. Poor journalism to not explain industry-specific lingo to your readers.
It is Electrical Engineering lingo...
While it has more historical roots then modern day practice the term is still used today in relation to a few different subsystems.
Way back BEFORE actually "printed" circuit boards were made designers would draft their schematics of their circuits and then conceptually place & arrange the electrical parts they were using on their chosen size & shape of circuit board.
"Tape out" refers to the actual placing of tape on the copper circuit board to protect the copper elements the designers wished to use as "wires" interconnecting the electrical parts that they were planning on attaching to the circuit board.
Once "taped out" the circuit board would be dropped in an acid bath which would remove all the copper that was not covered by tape.
After cleaning (and optional drilling) as well as coatings to protect the exposed copper the finished bare PCB (we can call it 'printed' as there is now a circuit schematic etched/printed on it!) can be assembled with electrical devices to become a product.
(modern times they use "photo etch" instead of tape)
In Electrical Engineering "tape out sets in stone" the physical locations and electrical connections of the devices. Afterwards the design is transferred to PCB manufacturing for fabrication and 'stuffing' (of the parts).
In reference to CHIP's, the planning for all the gates, devices & layers of material are complete and ready to send to the factory for fabrication.
