Hmm... the picture on the screen starts to differ from what's actually going on inside the chip. I don't like that.
I'll take care of the I/O blocks for now, and then I'll come back to the clock.
#fpga #nextpnr #gowin

Great! We have clock lines!
This was a tricky piece if only because the GB50 wire (and company) are not used on any net and thus it is always inactive, but I highlight depending on the status of the other wires 😜

Okay, maybe it's not the best course because I don't see a way to get null here as the author shows.

So I added the clock lines in the #nextpnr #gowin GUI, I didn't like them so I'll redo everything tomorrow. In the meantime, I'll watch a three-hour Javascript course🙂

Displaying the connection of the 4 global clock taps to the branches. WIP.

#gowin #nextpnr #fpga

gee, the global lines are done. What's left is clock lines, a couple of the MUX things, and I/O pins.

Ponies of the Apocalypse.

I don't know what it is, but I already have a feeling it's not a barrel of honey🙂
Which is logical in general: if you can not afford an exact number comparison, then you will have a huge hassle with special constants like zero or empty or NULL as in C.
And was it worth it to give up the word "integer"? 😉

I need to somehow overcome the huge block in my brain that manifests itself in my aversion to programming languages whose type system begins with "all numbers are floating point numbers.
My brother has decided to take up Javascript and I need to learn a few things so I can keep the conversation going.

Backup day (for me, weekly) so I can distract myself and reflect on stuff.
The NVME2.0 spec legitimizes the key-value mechanism as an alternative to the block structure. That is, no level of transcoding and mimicking the blocks of the old HDDs. Atomic writing of a key-value pair.
Cool!
And... I'll never trust such a device with anything important: block devices in OSes are as shiny as a cat's balls, but this new thing can fail at any moment😜

also in a month I will get a 120 MHz oscilloscope and the process of investigating I/O logic and PLL will be much easier. (although I highly doubt that there will be an honest 120MHz, but 70-90 can be counted on).

The new GW1NR-9 board arrived, courtesy of @pepijndevos !!!
This version is out of the box, flashing the LEDs happily:) I expect February to be very interesting:)

I say Feb because that month the priority is #nextpnr GUI and I basically can't get out of the zone and multitask.
#gowin #fpga

Made almost all the vertical wires: 1, 2, 4, 8 hops. I left room for the clock lines and am moving on to the horizontal ones.

You know what would help? Shutting down those fucking schools in the beginning, not when our asses are on fire and all the teachers are sick!
But I don't think I care anymore: I bet these morons will open the schools the very first thing because it's not like we've been living in a pandemic for years and suddenly this time will be different.

Two cartridges for DeskJet 2050a cost more than the printer itself, and besides, the crap tends to dry out by the time I need to print something urgently. Not often, once a month or so.
I'm thinking about looking at laser printers. It's scary that there's another idiocy --- chips in printers and cartridges. Why can't they just sell a serviceable product?

Now I admire artists, and for some reason I fear that this magic will disappear if I learn to paint myself🙂
