  • (c) automatically generating constraint files for physical synthesis from the timing constraints;
  • (d) automatically generating host software code from the software interface definitions;
  • (e) automatically generating verification testbenches from the verification test cases;
  • (f) synthesizing the RTL code with a synthesis toolchain using the constraint files to produce a bitstream; and
  • (g) executing the verification test cases against hardware programmed with the bitstream to validate functional correctness.

Dependent Claims​

Claim 2: The method of Claim 1, wherein the specification file is a YAML-based format with structured sections for types, behaviors, algorithms, signals, finite state machines, and test cases.

Claim 3: The method of Claim 1, wherein the RTL code is Verilog-2005 compliant for FPGA synthesis.

SVA generation/trinity-nexus/lang/src/verilog_codegen.zig70-100extractSignalsFromTypes(), ValidationWarning struct

Gaps Blocking Filing​

  1. Missing explicit constraint generation code - XDC files are manually written, not auto-generated from spec. Need to add XDC generation to verilog_codegen.zig.

  2. No formal proof of testbench correctness - Need to add documentation showing generated testbenches verify all spec behaviors.

  3. Missing end-to-end example - Need a complete walkthrough: .vibee → RTL → constraints → host → tests → synthesis → hardware verification.

  4. Prior art search incomplete - Need to search for existing "spec-first" FPGA compilation tools (e.g., Chisel, Amaranth, PyMTL).

Prior Art Avoidance Notes​

  • Chisel (Scala) - Generates Verilog from Scala code, but not from declarative YAML specs with separate verification test case generation.
  • Amaranth (Python) - Python-based hardware construction, but not spec-driven with host software generation.
  • PyMTL - Python-based modeling and testing, but targets simulation not FPGA synthesis.
  • nMigen - Python-based hardware description, but lacks unified spec → RTL + constraints + host + tests pipeline.

Novelty: Unified single-spec pipeline driving entire hardware/software/verification stack with declarative YAML format.

Filing Recommendation: AFTER 1 SPRINT​

Rationale: Core invention is solid (spec → RTL/constraints/host/tests), but need to implement missing constraint generation and document end-to-end flow. 75% ready.

Gaps Blocking Filing​

  1. Missing DSP block details - vsa_dsp_bind_block module not shown in main file. Need to verify DSP48E1 usage and add to specification.

  2. No formal proof of correctness - Need to add mathematical proofs for bind/unbind/bundle/similarity operations in ternary algebra.

  3. Missing performance benchmarks - Need quantitative speedup vs software implementation (e.g., "100x faster for 10K-dimensional vectors").

  4. Prior art search incomplete - Need to search for existing FPGA accelerators for hyperdimensional computing or vector symbolic architectures.

Prior Art Avoidance Notes​

  • Hyperdimensional Computing FPGA implementations - Several academic papers exist, but focus on binary hypervectors, not ternary trits.
  • Neuromorphic hardware accelerators - Focus on spiking neural networks, not VSA operations (bind/unbind/bundle).
  • Standard FPGA DSP blocks - DSP48E1 is generic Xilinx primitive, but novelty is in ternary-specific application.

Novelty:

  • Ternary (not binary) hardware implementation with 2-bit trit encoding
  • Majority vote logic for bundle operation (not standard in binary HDC)
  • Unified protocol for VSA operations over UART

Filing Recommendation: FILE NOW​

Rationale: Strong implementation evidence with complete Verilog code, protocol specification, and working hardware. 90% ready. Minor gaps (DSP details, proofs) can be filled during prosecution.

P3: SYNTHESIS-MEMORY RECOMMENDATION SYSTEM​

Independent Claim​

Claim 1: A method for recommending synthesis strategies for FPGA designs based on semantic similarity, comprising:

  • (a) extracting semantic features from a hardware design description, the semantic features comprising behavioral descriptions, signal names, state machine structures, and algorithmic patterns;
  • (b) encoding the semantic features as a hypervector in a vector symbolic architecture space, wherein the hypervector has a dimensionality of at least 10,000;
  • (c) comparing the hypervector to a historical database of previously synthesized designs, each previously synthesized design associated with a synthesis strategy and a synthesis outcome;
  • (d) identifying one or more similar previously synthesized designs based on cosine similarity in the vector symbolic architecture space;
  • (e) recommending a synthesis strategy for the hardware design description based on the synthesis strategies associated with the similar previously synthesized designs; and
  • (f) executing the recommended synthesis strategy to generate a bitstream for the hardware design description.

Dependent Claims​

Claim 2: The method of Claim 1, wherein the behavioral descriptions are extracted from structured specification files in a YAML-based format.

Claim 3: The method of Claim 1, wherein the state machine structures are extracted as finite state machine definitions comprising states, transitions, outputs, and timers.

Claim 4: The method of Claim 1, wherein the algorithmic patterns are identified by parsing behavior clauses for keywords indicative of mathematical operations, control flow, or data transformations.

Claim 5: The method of Claim 1, wherein the hypervector encoding comprises binding together feature hypervectors for each semantic feature using element-wise ternary multiplication.

Claim 6: The method of Claim 1, wherein the hypervector encoding comprises bundling feature hypervectors using majority vote logic to create a composite representation.

Claim 7: The method of Claim 1, wherein the historical database stores hypervectors, synthesis strategies (Yosys optimization flags, nextpnr placement seeds), and synthesis outcomes (timing slack, resource utilization, runtime).

Claim 8: The method of Claim 1, wherein the cosine similarity is computed as the dot product of hypervectors divided by the product of their magnitudes, returning a value in the range [-1, 1].

Claim 9: The method of Claim 1, wherein the recommended synthesis strategy is selected as the most frequently successful strategy among the top K most similar previously synthesized designs.

Claim 10: The method of Claim 1, further comprising updating the historical database with the hypervector, synthesis strategy, and synthesis outcome after synthesizing the hardware design description.

FSM extraction/trinity-nexus/lang/src/vibee_parser.zigN/AFSMDef struct with states, transitions, outputs, timers

Gaps Blocking Filing​

  1. No implementation of synthesis strategy mapping - The system exists for semantic search, but there's no code mapping similarity scores to Yosys/nextpnr parameters.

  2. Missing historical database schema - Need to design database schema storing: hypervector, synthesis flags (Yosys -abc9, -nobram, etc.), nextpnr --seed, --freq, outcomes (timing slack, utilization, runtime).

  3. No learning algorithm - Need to implement recommendation logic (e.g., "most successful among top K", "weighted by similarity score", "reinforcement learning").

  4. No validation of effectiveness - Need to prove that recommended strategies actually improve synthesis outcomes vs random/default strategies.

  5. Prior art search incomplete - Need to search for existing machine learning-based synthesis optimization tools (e.g., Google's "FirePlace", academic papers on ML for FPGA compilation).

Prior Art Avoidance Notes​

  • Google "FirePlace" - Machine learning for FPGA placement, but uses graph neural networks on netlists, not VSA hypervectors on behavioral specs.
  • Academic ML for EDA - Various papers on ML for logic synthesis, but focus on binary features, not hypervector similarity.
  • StandardEDA tools - Vivado HLS, Vitis, etc. have heuristic optimization, but no semantic similarity search based on behavioral descriptions.

Novelty: Using VSA hypervectors (not GNNs) to encode behavioral semantics (not netlists) for synthesis strategy recommendation.

Filing Recommendation: NOT READY​

Rationale: Core idea is novel, but implementation is missing. Only 40% ready. Need to build:

  1. Synthesis history database
  2. Feature extraction from specs → hypervectors
  3. Recommendation algorithm
  4. Validation experiments

Research Needed: 2-3 sprints to build minimal working prototype and validate effectiveness.
