#tinytapeout For some reason, the Verilator #linter used in the GitHub actions doesn't know about the Sky130 standard cells. However, I do directly instantiate some inverter cells in my ring oscillator TRNG design.

Consequence: the action fails because the linter raises an error.

Solution? Disable the linter.

The ultimate yak shave: to implement its last generation of #LispMachines, Symbolics developed a complete #EDA toolset in #CommonLisp called NS that enabled them to design and verify their ASICs, gate arrays, and boards from architecture to photomasks for manufacturing.

Thanks to @jpreisendoerfer for scanning the article "The #Symbolics #Ivory Design and #Verification Strategy" that was unavailable on the net until now.

The #XeroxAlto turns 50 years old and it's wild how much of how we're using personal computers today can be traced back to this machine. It was truly groundbreaking!

Hey!
The Masto-ASIC-nerds!
What are the step to print its own ASIC chip? Do we have to provide a file in a specific format? What are the specific masks to provide? Or only the VeriLog files? Anything else to provide?

And, also, is it expensive? What kind of prices, for simple circuit, do we have to print, for testing purpose? And with what kind of quantity?

I already know how to design a CMOS circuit, I just want to print one, just to discover. In my case, the chip will be used to forward digital signals in a high frequency 😄​

Patentstreit beigelegt: Intel wendet Milliardenzahlung an VLSI ab

Die Patentverwertungsgesellschaft VLSI wollte vor Gericht nicht sagen, wer hinter ihr steckt. Damit entgeht Intel einer Forderung von 4 Milliarden US-Dollar.

The Smallest Chip Ever - IBM Two-Nanometer Chip

"IBM’s 2-nanometer (nm) chip technology puts 50 billion transistors, each the size of roughly five atoms, on a space no bigger than your fingernail. The landmark technology—the smallest, most powerful microchip ever developed—could quadruple the life of cell-phone batteries and slash the carbon footprint of data centers, among other things."

Answers to the #quiz Q2: almost 5GHz (post-layout simulation),

and to the #quiz Q3: it's incredible, but e.g. Pentium 4 or the first AMDs' 64-bit x86 processors were# manufactured in 130nm (SOI) technology

Odpověď na #quiz Q2: skoro 5GHz (post-layout simulace 🙂 )

a na #quiz Q3: je to neuvěřitelné (že už je to skoro 20 let), ale na 130 nm (SOI) se vyráběly třeba procesory Pentium 4 nebo první 64-bitové x86 procesory AMD 🙂

Answer to the #quiz Q1: 3-stage, 8-transistor ring oscillator in 130nm (150nm) #sky130 technology node.

Such a simple circuit has many applications: #TRNG, #PUF, or wafer/process characterization.

The 130nm technology node was cutting edge 20 years ago. Do you think it's much slower than the recent few nm technology nodes?

#quiz Q2: how fast it oscillates?

#quiz Q3: Do you remember any high-end chips manufactured in a comparable technology node?

Odpověď na #quiz Q1 z
@belohoub/109360822459034932: layout 3-stupňového kruhového oscilátoru z 8 transistorů ve 130nm (resp. 150nm) technologii #sky130.

I takový jednoduchý obvod má mnoho aplikací: #TRNG, #PUF a třeba charakterizace procesu/waferu.

130nm byla "pokročilá technologie" asi před 20 lety ...

#quiz Q2: jak rychle myslíte, že tento oscilátor bude oscilovat?

#quiz Q3: pamatujete si nějaké zajímavé výkonné čipy vyráběné v podobné technologii?

V sobotu jsem uchazečům, kteří přišli do laboratoře na #KIB dal malý #quiz: Q1): Co je na obrázku? A dokázali byste popsat funkci nebo nakreslit schema?

Odpověď a Q2 si nechám na zítra 😉

A simple #quiz for visitors of the #KIB lab at #FIT #CTU on Saturday: Q1) What is in the picture? Are you able to describe the circuits' function or draw a schematic?
