PDK\n\n1. [#3](https://github.com/wafer-space/gf180mcu/pull/3): The seal ring generator has been updated.\n - Now actually includes the glass cut.\n - Pplus does not overlap comp, as required by DRC.\n2. [#3](https://github.com/wafer-space/gf180mcu/pull/3): Filler generation has been updated to ensure 10um spacing to the seal ring. (This was only a problem for smaller slot sizes).\n\n### Template\n\n1. The core ring now [connects to all vss pads again](https://github.com/wafer-space/gf180mcu-project-template/commit/c119e25b04b1dc3619bcd66cb508f901fd976410). (thanks @tnt!)\n2. [#22](https://github.com/wafer-space/gf180mcu-project-template/pull/22): Magic has been updated with fix that significantly reduces peak memory usage.\n3. [#21](https://github.com/wafer-space/gf180mcu-project-template/pull/21): The `render-image` Make target renders the GDS layout.\n4. [#21](https://github.com/wafer-space/gf180mcu-project-template/pull/21): The CI has been updated.\n - Commands in the nix shell are now only executed once. (thanks @Egor Lukyanchenko!)\n - Create a summary and upload artifacts (gds and image) ([Example](https://github.com/wafer-space/gf180mcu-project-template/actions/runs/19543720582))\n5. [#23](https://github.com/wafer-space/gf180mcu-project-template/pull/23): Workaround for a PDN issue.\n6. [#24](https://github.com/wafer-space/gf180mcu-project-template/pull/24): Fix antenna violations using `DRT_ANTENNA_REPAIR_ITERS` (disable if any issues occur).\n7. The [PDK version](https://github.com/wafer-space/gf180mcu-project-template/commit/b20168925c46fdd292e6084f31bfd8d312379d7e) has been pinned.\n\nPlease update your repository in line with the template and clone the latest PDK.", "author": { "id": "323371864074485771", "name": "mole99", "discriminator": "0000", "nickname": "Leo Moser (mole99)", "color": null, "isBot": false, "roles": [ { "id": "1423020172595298314", "name": "Mod", "color": null, "position": 4 } ], "avatarUrl": "2025-11_media/3c7c17f3225f6e56f4dccd83f14383f2-73F83.png" }, "attachments": [], "embeds": [], "stickers": [], "reactions": [ { "emoji": { "id": "", "name": "❤️", "code": "heart", "isAnimated": false, "imageUrl": "2025-11_media/2764-A3D25.svg" }, "count": 6, "users": [ { "id": "384390069412429834", "name": "polyfractal", "discriminator": "0000", "nickname": "BreakingTaps", "color": null, "isBot": false, "avatarUrl": "2025-11_media/8d8c1d8b8ad51d6cdb1a47512c39b297-42908.png" }, { "id": "538398807986274304", "name": "rzioma", "discriminator": "0000", "nickname": "ReJ aka Renaldas Zioma", "color": null, "isBot": false, "avatarUrl": "2025-11_media/f2ec4a3c78aa64de4ebf8efb563cc011-91657.png" }, { "id": "543162393413287956", "name": "h.tamas", "discriminator": "0000", "nickname": "htamas", "color": null, "isBot": false, "avatarUrl": "2025-11_media/1-B2132.png" }, { "id": "754661674145022032", "name": "noritsunaimamura", "discriminator": "0000", "nickname": "Noritsuna Imamura", "color": null, "isBot": false, "avatarUrl": "2025-11_media/ba250adfde87b0f7a20559209aaf5bac-0CCB8.png" }, { "id": "803213471402688522", "name": "_luke_w_", "discriminator": "0000", "nickname": "LukeW", "color": null, "isBot": false, "avatarUrl": "2025-11_media/a2f98861602ee8229f4eb87d5c25d1b1-5FBF4.png" }, { "id": "840182560252624916", "name": "logic_destroyer", "discriminator": "0000", "nickname": "asic destroyer", "color": null, "isBot": false, "avatarUrl": "2025-11_media/6f21ec45bc9221220509b769f634344b-E96BD.png" } ] } ], "mentions": [ { "id": "596068704471482370", "name": "246tnt", "discriminator": "0000", "nickname": "tnt", "color": null, "isBot": false, "roles": [], "avatarUrl": "2025-11_media/88d17af9d19ab43565b0c46751ef7d12-DFEE5.png" }, { "id": "709384666909507634", "name": "egorxe", "discriminator": "0000", "nickname": "Egor Lukyanchenko", "color": null, "isBot": false, "roles": [], "avatarUrl": "2025-11_media/3-FB033.png" } ], "inlineEmojis": [ { "id": "", "name": "\uD83D\uDCE2", "code": "loudspeaker", "isAnimated": false, "imageUrl": "2025-11_media/1f4e2-C9D9D.svg" } ] }, { "id": "1441135690678145144", "type": "ChannelPinnedMessage", "timestamp": "2025-11-20T18:38:43.664+00:00", "timestampEdited": null, "callEndedTimestamp": null, "isPinned": false, "content": "Pinned a message.", "author": { "id": "323371864074485771", "name": "mole99", "discriminator": "0000", "nickname": "Leo Moser (mole99)", "color": null, "isBot": false, "roles": [ { "id": "1423020172595298314", "name": "Mod", "color": null, "position": 4 } ], "avatarUrl": "2025-11_media/3c7c17f3225f6e56f4dccd83f14383f2-73F83.png" }, "attachments": [], "embeds": [], "stickers": [], "reactions": [], "mentions": [], "reference": { "messageId": "1441113806041383023", "channelId": "1423348662318272592", "guildId": null }, "inlineEmojis": [] }, { "id": "1441173471253237901", "type": "Default", "timestamp": "2025-11-20T21:08:51.255+00:00", "timestampEdited": null, "callEndedTimestamp": null, "isPinned": false, "content": "@Leo Moser (mole99) Is the environment of the leo/gf180 branch of libre lane good ?

But mostly the issue of the way it is currently implemented in magic comes from early on struggling with what was _meant_ by a 5V or 6V transistor, along with largely unreadable documentation trying (badly) to explain it. There were no 5V devices in the device model files originally. I added those to the model files recently. I could certainly redo the magic tech file to separate the 5V and 6V transistor types (now that there is a device model for each of them) and use the V5_XTOR (\"FET5VDEF\" in the magic techfile) to distinguish them (and apply the device length rules separately for each of them).", "author": { "id": "1365118310701600900", "name": "rtimothyedwards_19428", "discriminator": "0000", "nickname": "Tim Edwards", "color": null, "isBot": false, "roles": [], "avatarUrl": "2025-11_media/6bcc8e61db497b620550682309ace5d5-D89B4.png" }, "attachments": [], "embeds": [], "stickers": [], "reactions": [], "mentions": [ { "id": "220639106915368960", "name": "tholin", "discriminator": "0000", "nickname": "Tholin", "color": null, "isBot": false, "roles": [], "avatarUrl": "2025-11_media/edae5aadf146133e0448bfb1f0fa91c4-62B19.png" } ], "inlineEmojis": [] }, { "id": "1441869215614369853", "type": "Default", "timestamp": "2025-11-22T19:13:29.637+00:00", "timestampEdited": null, "callEndedTimestamp": null, "isPinned": false, "content": "IMHO it's fine to only have `mv` to represent 5V/6V , but the `V5_XTOR` layer still need to be generated if length is too small to be 6V to comply with the DRC requirement ...

See the [README](https://github.com/wafer-space/gf180mcu-project-template?tab=readme-ov-file#choosing-a-different-slot-size) for more information.\n - The CI now also runs for all slot sizes in the upstream repo `wafer-space/gf180mcu-project-template`: https://github.com/wafer-space/gf180mcu-project-template/actions/runs/19697592187\n- Better SRAM power connections ⚡\n - `pdn_cfg.tcl`: better connectivity for the SRAM orientations. Please make sure to update your PDN config!\n- The PDK has been updated to 1.1.2\n - NP.12 and PP.12 reimplemented\n - Wide metal check fixed\n\nPlease update your projects and PDKs.\nThe latest precheck tag is [1.0.1](https://github.com/wafer-space/gf180mcu-precheck/releases/tag/1.0.1).", "author": { "id": "323371864074485771", "name": "mole99", "discriminator": "0000", "nickname": "Leo Moser (mole99)", "color": null, "isBot": false, "roles": [ { "id": "1423020172595298314", "name": "Mod", "color": null, "position": 4 } ], "avatarUrl": "2025-11_media/3c7c17f3225f6e56f4dccd83f14383f2-73F83.png" }, "attachments": [], "embeds": [], "stickers": [], "reactions": [ { "emoji": { "id": "", "name": "\uD83C\uDF89", "code": "tada", "isAnimated": false, "imageUrl": "2025-11_media/1f389-5C738.svg" }, "count": 5, "users": [ { "id": "538398807986274304", "name": "rzioma", "discriminator": "0000", "nickname": "ReJ aka Renaldas Zioma", "color": null, "isBot": false, "avatarUrl": "2025-11_media/f2ec4a3c78aa64de4ebf8efb563cc011-91657.png" }, { "id": "596068704471482370", "name": "246tnt", "discriminator": "0000", "nickname": "tnt", "color": null, "isBot": false, "avatarUrl": "2025-11_media/88d17af9d19ab43565b0c46751ef7d12-DFEE5.png" }, { "id": "732347216412278825", "name": "urish", "discriminator": "0000", "nickname": "urish", "color": null, "isBot": false, "avatarUrl": "2025-11_media/2b6c3aac0ae09fc8a72a4b2e17d7f9c9-39032.png" }, { "id": "754661674145022032", "name": "noritsunaimamura", "discriminator": "0000", "nickname": "Noritsuna Imamura", "color": null, "isBot": false, "avatarUrl": "2025-11_media/ba250adfde87b0f7a20559209aaf5bac-0CCB8.png" }, { "id": "840182560252624916", "name": "logic_destroyer", "discriminator": "0000", "nickname": "asic destroyer", "color": null, "isBot": false, "avatarUrl": "2025-11_media/6f21ec45bc9221220509b769f634344b-E96BD.png" } ] } ], "mentions": [], "inlineEmojis": [ { "id": "", "name": "\uD83D\uDCE2", "code": "loudspeaker", "isAnimated": false, "imageUrl": "2025-11_media/1f4e2-C9D9D.svg" } ] }, { "id": "1443237159917191300", "type": "ChannelPinnedMessage", "timestamp": "2025-11-26T13:49:12.974+00:00", "timestampEdited": null, "callEndedTimestamp": null, "isPinned": false, "content": "Pinned a message.", "author": { "id": "323371864074485771", "name": "mole99", "discriminator": "0000", "nickname": "Leo Moser (mole99)", "color": null, "isBot": false, "roles": [ { "id": "1423020172595298314", "name": "Mod", "color": null, "position": 4 } ], "avatarUrl": "2025-11_media/3c7c17f3225f6e56f4dccd83f14383f2-73F83.png" }, "attachments": [], "embeds": [], "stickers": [], "reactions": [], "mentions": [], "reference": { "messageId": "1443237097543565542", "channelId": "1423348662318272592", "guildId": null }, "inlineEmojis": [] }, { "id": "1443239004173762720", "type": "Default", "timestamp": "2025-11-26T13:56:32.679+00:00", "timestampEdited": null, "callEndedTimestamp": null, "isPinned": false, "content": "Will quarter slots be 1/4 of the price ? \uD83D\uDE05", "author": { "id": "596068704471482370", "name": "246tnt", "discriminator": "0000", "nickname": "tnt", "color": null, "isBot": false, "roles": [], "avatarUrl": "2025-11_media/88d17af9d19ab43565b0c46751ef7d12-DFEE5.png" }, "attachments": [], "embeds": [], "stickers": [], "reactions": [], "mentions": [], "inlineEmojis": [ { "id": "", "name": "\uD83D\uDE05", "code": "sweat_smile", "isAnimated": false, "imageUrl": "2025-11_media/1f605-42B43.svg" } ] }, { "id": "1443240626698063892", "type": "Default", "timestamp": "2025-11-26T14:02:59.519+00:00", "timestampEdited": null, "callEndedTimestamp": null, "isPinned": false, "content": "I assume the cost of packaging will not go down by much.
