 The puzzle of goat, wolf and hay

six ways of arriving at a solution

"Albert Einstein was once asked what the difference was between him and the average person. He said that if you asked the average person to find a needle in the haystack, the person would stop when he or she found a needle. He, on the other hand, would tear through the entire haystack looking for all the possible needles. With creative thinking, one generates as many alternative approaches as one can." - EINSTEIN’S NEEDLE IN THE HAYSTACK

How to expand the semiconductor industry talent pool

“If there are no young writers, there will be no future readers. Every group of young writers that are coming along is continuing the tradition of reading and writing. They’re part of a very long history. But, if all of a sudden there weren't any young writers, that tradition would stop. That's why it's a good idea to encourage young writers on the idea of books and reading. More young readers and writers need to come along, or else, it will all come to an end”. - Margaret Atwood

Rainbows

          Rainbows are red,orange,yellow,green,blue,indigo,and violet. Rainbows come when it is sunny and rainy. Some are wrong because they start with purple and end in red . Rainbows are verrrrrrrrrrrrrrrrrrrrrrrry beautiful and different.They start in red and end in purple. Did you know there are double rainbows? Did you they do not have clouds? Well, it's true.

Hi what is nature?

 Nature is all four elements put together.Fire ,water,air,and earth are the elements.It can be plants or water or the sun.Did you know we sometimes eat nature?Nature always grows  and when I say always I mean always.It is veeereeeeeeeeeeeeeeeeeeerrrrrrrrrrrrrrrrrrrrrrrrryyyyyyyyyyyyyy healthy!!!!!!!!!!!!!!!The sun is very powerful it has so much energy if it was not real it would be bad.But heat is also a deadly condition.Plants can react to pain. Did you know only 85% of plant is found in  the ocean.Humans only use 1% of all available water. Well if you want to learn more, go out and find more fun facts about nature!

Okay so i finally get it - Intel can leapfrog TSMC in process tech in 1H 2024 if they get Power Via working ASAP? And at that point there will be parity / even better features than TSMC. Presume TSMC will insert PBN in 2nm? Or will that be a 3+ node? Anyone familiar w/ 2nm

I haven't been reading the news lately, but TSMC 3nm seems to be going well again? So Granite Ridge and Navi4 have a good chance of using 3nm as originally planned.

I'm looking at this again, and I don't see any dedicated DMI mesh tiles. Are they just using 8/16 of the PCIe lanes for DMI?

That would explain Sapphire Rapids maxing out at 112 lanes, 8/16 of the remaining 16 lanes are downclocked and used for DMI with the Emmitsburg PCH. https://t.co/EUm5tCHjIB

Career Development

Putting common career advice to the test 

Track what excites you or scare you

What metrics mean something

Know what options are available – Networking, Books, Other organization knowledge, Public figures

Which do you see yourself in? Make a future resume. Keep refining it.

Do you know your obstacles? – Feedback

What are the new skills needed to your final destination? – Experience, Education- formal course, online course, Books, Data (eg Strategy, risk as opportunity), Dealing with Complexity, Modeling a situation, Your learning style and growth through challenging with other styles.

Your support team – Find a Mentor, Keep family in the ring, Sustaining motivation and going back to the beginning if this is not the right path.

Giving it back – Mentoring

Pushing ourselves to find the limit

Plaza with different opportunities. There are many steps. Do you want to take one path and reach the pinnacle or go up a bit on the others, which could mean having to climb new stairs and going down a few. Or find lateral bridges.

3. What is clk insertion delay? (Clock tree balancing)

4. generate div by 2, div by 3 and div by 4 clock - state machine showing counter design

5. First  there is a register 

    I want to latch the output only with another pulse as an enable

    Now with a config bit as a mux sel want both 1 and 2 .

   Mux cannot be after the flop or latch as it will glitch

(I put mux on data input and clk input for the first register, wondering how to tap two different outputs - one after the first reg and two after the second latch without  amux to select. Answer is to put the mux for data (output of first reg which will be input for the second case of latching, the other input is original d, so instead of using first reg for plain output, we now use second latch for it)and mux for clock (pulse or original clk)

This seems very close to pg 46 Clock Domain Crossing (CDC) Design & Verification Techniques Using SystemVerilog - Figure 33 - Sample ASIC & FPGA synchronizer cell for synthesis and simulation

6. On the same chip if clock is delayed between two sections how do you ensure the data is still captured fine as there is a ck-q delay and the clock might have shifted by that much. Use the data on the opposite edge of the clock than the launching one.

7. How do you sync fast to slow clk domain and vice a versa

8. Will duty cycle uncertainty matter if the design is one edge based only?

9. Are clock and its generated clock timed?
