Sovryn KAN NPU V2 Architecture (Open Source Release)

Welcome to the public documentation and core repository for the Sovryn KAN NPU V2. This repository contains the template-native physical design (Verilog RTL) and the final signoff data for the IHP-SG13G2 (130nm) open open-source hardware tapeout path.

This repository is licensed under the Apache 2.0 License. The codebase is permanently anchored to the Base L2 blockchain for prior art protection.

Tapeout Status: IHP / Magic Signoff Blocker

We have successfully routed the KAN NPU V2 using our autonomous zero-shot spatial compiler. However, the current iteration is blocked by external false-positive issues in the IHP-SG13G2 PDK Magic rules:

• tapeoutDecision = no_go
• remediationClass = external_blocker

Main remaining blockers in the signoff stage:

• 8 KLayout antenna errors (Standard, easily patchable via diode insertion)
• 32 KLayout DRC errors (metal1_pin_Offgrid) (Standard)
• 15154 Magic illegal-overlap feedback markers (CRITICAL EXTERNAL BUG)

Current v16 narrowing

Prometheus v16 narrows the remaining Magic path to bounded layer-role conflict classes:

• obsm7 / metal7 -> upper_obstruction_metal_conflict / signoff_abstract_vs_top_routing
• obsm6 / metal6 -> upper_obstruction_metal_conflict / signoff_abstract_vs_top_routing
• obsm6 / via6 -> upper_obstruction_via_conflict / signoff_abstract_vs_top_routing
• obsm3 / metal3 -> interior_obstruction_metal_conflict / library_abstract_vs_core_routing
• obsm3 / via3 -> interior_obstruction_via_conflict / library_abstract_vs_core_routing

In other words, the Magic path is now narrowed from:

• raw overlap counts
• to clustered families
• to geometry
• to final-view regions
• to candidate cell families
• to candidate instances
• to side/envelope classes
• to layer-role conflict classes

• The content and forensic JSON files were generated from the repo-native autonomous silicon closed-loop and signoff copilot flow (Prometheus v16), not from an ad hoc hand-edited evidence pack.
