Today is a good time to announce that I'm working on a GSoC project this summer! 🎉️

Google Summer of Code is a program from Google that sponsors students to work on open source projects during the summer months.

My project is called "Improving SDF support in Icarus Verilog" and I will explain what it is about in the following posts. But just as a heads up: it has to do with chip design.

Waveform Generator ACCEPTED for MPW-7! 🎉

I finally got the news that one of my projects, a digital waveform generator, was accepted into the 7th Google-sponsored shuttle run for SKY130.

I will get the actual chips back in a couple of months and can't wait to test them!

Here is the list of projects on this run, you can find the Waveform Generator under Location E7, Slot 33:

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?

#sky130 #VLSI #OSHW #Magic #xschem

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?

Na #FIT #CVUT se můžete - máte-li zájem - potkávat i s #hardware.

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?

The answer and Q2 tomorrow 😉

Hi everyone! This is my very first toot :)

I would like to take the opportunity to present one of my latest projects:

A generic waveform generator implemented as an ASIC using the open source SKY130 PDK. With a bit of luck, this will be fabricated in the MPW-7 Shuttle through the Open MPW Program.
