Blocker 2: Fix uart_top.v (CRITICAL — 2 hours)

Problem

trinity-nexus/output/lang/fpga/uart_top.v has syntax errors:

1. Line 430: function signed [1:0] trit_value — invalid Verilog-2005
2. Signal name conflicts: rx_data used as both 256-bit and 8-bit

Acceptance Criteria

• uart_top.v syntax passes Yosys without errors
• uart_top.json generated successfully
• uart_top.bit generated successfully
• P2_EVIDENCE_TABLE.md updated with E4.5, E8.3

Fix Strategy

Fix 1: Signed Function Syntax

BEFORE (line ~430):

function signed [1:0] trit_value(input [1:0] encoded);
    case (encoded)
        2'b10: trit_value = -1;
        2'b00: trit_value = 0;
        2'b01: trit_value = +1;
    endcase
endfunction

AFTER:

function [1:0] trit_value;
    input [1:0] encoded;
    reg signed [1:0] result;
    begin
        case (encoded)
            2'b10: result = -1;
            2'b00: result = 0;
            2'b01: result = +1;
        endcase
        trit_value = result[1:0];
    end
endfunction

Fix 2: Signal Name Conflicts

FIND:

grep -n "rx_data" trinity-nexus/output/lang/fpga/uart_top.v

FIX: Rename one of the conflicting signals

• rx_data [255:0] → rx_vector [255:0]
• OR rx_data [7:0] → rx_byte [7:0]

Commands

# 1. Navigate to generated file
cd /Users/playra/trinity-w1/trinity-nexus/output/lang/fpga

# 2. Fix the file
# MANUAL EDIT required for uart_top.v
# Use the fixes above

# 3. Test syntax with Yosys
cd /Users/playra/trinity-w1/fpga/openxc7-synth
docker run --rm --platform linux/amd64 \
  -v "$(pwd):/work" -w /work \
  regymm/openxc7 \
  yosys -p "synth_xilinx -flatten -abc9 -nobram -arch xc7 -top uart_top; write_json uart_top.json" \
  ../trinity-nexus/output/lang/fpga/uart_top.v

# 4. If Yosys succeeds, generate bitstream
./synth.sh ../trinity-nexus/output/lang/fpga/uart_top.v uart_top

Success Output

✅ uart_top.v fixed
   - Yosys: 0 errors
   - uart_top.json: generated (9.5 MB)
   - uart_top.bit: generated (3.83 MB)

Blocker 3: Parser values + SSOT Import (HIGH — 4 hours)

Part A: Parser values Field (2 hours)

Problem

vibee_parser.zig doesn't parse values field in type definitions.

Acceptance Criteria

• values field added to parser enum
• Parser extracts {name, value} pairs
• localparam declarations generated in Verilog
• Test spec validates behavior

Implementation

File: trinity-nexus/lang/src/vibee_parser.zig

Step 1: Add to TypeField enum

pub const TypeField = enum {
    base,
    description,
    generic,
    fields,
    enum,
    constraints,
    values,      // NEW
    encoding,    // NEW
    width,       // NEW
    // ...
};

Step 2: Parse values in type definition

if (std.mem.eql(u8, key, "values")) {
    const values = try parseValues(allocator, value);
    try type_fields.put(.values, values);
}

Step 3: Generate localparam in Verilog

// In verilog_codegen.zig
if (type_field.values) |values| {
    for (values) |v| {
        try writer.print("localparam {s} = {s};\n", .{v.name, v.value});
    }
}

Step 4: Test

# test_values.tri
types:
  State:
    encoding: one_hot
    width: 3
    values:
      - name: IDLE
        value: 3'b001
      - name: RUNNING
        value: 3'b010

Expected Verilog output:

localparam IDLE = 3'b001;
localparam RUNNING = 3'b010;

---

Part B: SSOT Import Generation (2 hours)

Problem

Constants are hardcoded in generated Verilog instead of imported from SSOT.

Acceptance Criteria

• protocol_defines.v generated from src/common/protocol.zig
• Generated Verilog includes `include "protocol_defines.v"
• Test validates constants match

Implementation

Step 1: Create generator File: trinity-nexus/lang/src/protocol_defines_gen.zig

const std = @import("std");

pub fn generate(allocator: std.mem.Allocator, src_path: []const u8) ![]const u8 {
    var buffer = std.ArrayList(u8).init(allocator);
    const writer = buffer.writer();

    try writer.writeAll(
        \\// Generated from src/common/protocol.zig
        \\// DO NOT EDIT
        \\
        \\`define SYNC_BYTE 8'hAA
        \\`define CMD_MODE 8'h01
        \\`define CMD_BIND 8'h02
        \\`define CMD_BUNDLE 8'h03
        \\`define CMD_SIMILARITY 8'h04
        \\`define CMD_BITNET 8'h05
        \\`define CMD_PING 8'hFF
        \\
        \\// Trit encoding
        \\`define TRIT_NEG 2'b10
        \\`define TRIT_ZERO 2'b00
        \\`define TRIT_POS 2'b01
        \\
    );

    return buffer.toOwnedSlice();
}

Step 2: Integrate into VIBEE File: trinity-nexus/lang/src/verilog_codegen.zig

// After module declaration
try writer.writeAll("\n`include \"protocol_defines.v\"\n\n");

Step 3: Update .tri spec

imports:
  - name: protocol
    path: "src/common/protocol.zig"
    generate_defines: true
