Path: spikenaut-core-sv/mem/ — see mem/README.md.

File	Lines	Use
merged_v2_weights.mem	256	16×16 weights → WeightRam ADDR=8
merged_v2_thresholds.mem	16	NeuronParamRam
merged_v2_decay.mem	16	NeuronParamRam (leak)
merged_v2_output_weights.mem	48	Vendored; not wired until multi-layer

Format: one 16-bit Q8.8 hex word per line (signed as needed). $readmemh skips // comments.

RTL

parameter string INIT_FILE = "NONE";  // typed string preferred
// when set: $readmemh(INIT_FILE, mem);

• Sim: $fopen precheck under `ifndef SYNTHESIS
• Synth: $readmemh for BRAM init (UG901)
• Paths relative to tool CWD (repo root in CI); Vivado build may force absolute generics

Source vault: Spikenaut-SNN merged_v2 dataset (re-copy after retrain; do not invent hex).
