| singham | Folks, OpenFPGA uses skywater-pdk. | 16:10 |
|---|---|---|
| singham | How are the final designs made? The placing of gates, their libraries and connection of wires? | 16:12 |
| singham | I wanted to know more about physical design if some of you know more | 16:12 |

| singham | Why is the cost of making photomasks so high? | 18:11 |
| singham | I saw cheapest foundaries have been setup for $5M only | 18:11 |
| singham | And I see on Wiki that photomasks can go around $40M - $100M | 18:12 |
| singham | I mean come on! | 18:12 |
| so-offish | Depends on the number of them you need, the resolution you're trying to hit, etc | 18:12 |
| so-offish | also there's some sophisticated processing algorithms that go into them nowadays | 18:13 |
| so-offish | Because of multipatterning and edge effects | 18:13 |
| singham | But still $40M ? Give me a million and I'll write it for you from scratch in the language you want. | 18:14 |
| singham | I mean it's like a 4 cm^2 thing. | 18:15 |
| so-offish | So I hand you the algorithm and you... translate it for $1M? lol | 18:15 |
| singham | :D | 18:15 |
| singham | I'll create the algo. No worries | 18:16 |
| singham | At $1M it is doable | 18:16 |
| so-offish | Oh your background is computational optics? | 18:16 |
| singham | Naah. I took a course in computational physics though | 18:18 |
| singham | nvm | 18:18 |
| singham | Aah wait | 18:19 |
| singham | It's written, "new mask shop" | 18:19 |
| singham | Mask cost from $250 to $100k | 18:20 |
| singham | in 2006 | 18:20 |

| singham | Typically, FPGAs have how many layers in it's IC? | 19:19 |
| singham | Say, a chip like iCE40? | 19:19 |
| singham | Like, there is a transistor, on top of it will there be more? | 19:20 |
| knielsen | singham: There's only one layer of transistors on a chip. On top of that are multiple layers of routing ("wires"), Don't know any numbers, but I think 10-20 layers of routing is not uncommon | 19:23 |
| singham | Wow. 10-20 layers! | 19:27 |
| singham | All chips have just 1 layers of transistors? | 19:28 |
| singham | knielsen: Thank you. | 19:37 |
| * singham will see you fine hobbits later | 19:37 | |

| Sarayan | 10-20 is a lot actually | 20:23 |
| Sarayan | iirc the latest wafers we've done are something like 7 metal layers? | 20:23 |
| Sarayan | (european project, finnish partner) | 20:24 |
| Sarayan | also, a cmos wafer run for a reasonable node is something like 100K nowadays, not millions | 20:26 |
| Sarayan | here you can see real prices for mpw runs where you pay by square millimeter: https://europractice-ic.com/schedules-prices-2023/ | 20:29 |
| tpb | Title: EUROPRACTICE | Schedules 2023 (at europractice-ic.com) | 20:29 |
| so-offish | 100k is an ancient node though, isn't it? | 20:54 |
