It packages SystemVerilog RTL, an instruction set, a bit\-exact simulator, a kernel compiler and host tools in one repository, targeting an Inspur YPCB\-00338 PCIe card with a Xilinx Kintex\-7 FPGA and two DDR3 channels\. The repo reports running ten models, including LFM2\.5, Qwen3 and Gemma variants, with decode and prefill throughput, DRAM utilization and bit\-exact agreement with the simulator\. It also describes 4\-bit quantization and MoE expert streaming from host storage\. The measurements are the project's own, not independently verified\. - The card uses a four\-column systolic matrix unit, LiteDRAM controllers calibrated by an on\-chip CPU, and a stream engine; the design closes at 133\.33 MHz with WNS \+0\.032 ns\. - Reported decode ranges from 3\.78 tok/s for Gemma 4 E4B int8/4\-bit head to 85\.8 tok/s for LFM2\.5\-230M 4\-bit, with DRAM at 82–94% of the 17\.1 GB/s DDR3\-1066 peak\. - 4\-bit weights use FP4 with two\-level block scales at 4\.25 bits per weight, keeping the LM head in int8; the repo reports 40–45% faster decode and a measurable perplexity cost\. - MoE models larger than 4 GiB stream experts from host storage; LFM2\.5\-8B\-A1B is reported at 10\.6 tok/s with 98\.5% slot hits, while Qwen3\.5\-35B\-A3B is 3\.95 tok/s with 62% hits and 153 MB streamed per token\. - The simulator is treated as the specification, and every configuration is claimed to match it token for token; the host adds 0\.17–0\.30 ms per token on omarchy for LFM2/Qwen3\. - The project invites contributions and requires ISA, simulator or RTL changes to keep pytest passing; performance claims should state measurement method\. ## Discussion themes Analyzed: 2026\-10\-07T13:00:44\.499147\+00:00 Analysis sample: Based on 28 of 41 usable stored comments.

Selected themes do not measure community opinion or how common a view is. ### LLM autonomy, novelty and ground\-truth limits Replies dispute whether AI hardware design counts as AI developing its own hardware\. Critics say a human prompted the LLM and set up the simulation, LLMs lack initiative, cannot confirm physical ground truth, and mainly reuse training data; others argue prompting can be automated and brute\-force search may count as invention\. Simulation accuracy is raised as the hard part\.

Sources: [Comment 49982136]() ### Economic tradeoffs of baking models into silicon Commenters ask why labs do not burn frontier models into chips\. Replies cite model SOTA moving faster than chip design and production, requiring long commitments, while others note older 'good enough' models still serve large token volumes and ASIC speed could be worth it\.

Weights and kernels are seen as too variable to bake in, with suggestions like ROM or blank chips with weights burned in later\.
