Multi-simulator expertise for functional verification of FPGA designs

General

What this skill does


# HDL Simulation Skill

## Overview

Expert skill for HDL simulation across multiple simulators, enabling comprehensive functional verification of FPGA designs.

## Capabilities

- Generate simulation scripts (do files, tcl)
- Configure ModelSim/Questa simulations
- Configure Vivado Simulator (xsim)
- Configure VCS and Xcelium simulations
- Analyze waveforms for debugging
- Generate VCD and FSDB dumps
- Configure code coverage collection
- Support mixed-language simulation

## Target Processes

- functional-simulation.js
- testbench-development.js
- uvm-testbench.js
- constrained-random-verification.js

## Usage Guidelines

### Simulator Setup
- Create project-specific compilation scripts
- Configure library mappings
- Set up include paths and search paths
- Define simulation options
- Configure waveform dump formats

### ModelSim/Questa
```tcl
vlib work
vlog -sv +incdir+../rtl ../rtl/*.sv
vsim -voptargs="+acc" tb_top
add wave -recursive /*
run -all
```

### Vivado Simulator (xsim)
```tcl
xvlog --sv ../rtl/*.sv
xelab -debug typical tb_top -s tb_sim
xsim tb_sim -runall
```

### VCS
```bash
vcs -sverilog -debug_access+all -f filelist.f -o simv
./simv +vcs+vcdpluson
```

### Waveform Analysis
- Identify timing relationships
- Trace signal propagation
- Compare expected vs. actual
- Use markers for measurements
- Create protocol decoders

### Coverage Collection
- Statement coverage
- Branch coverage
- Toggle coverage
- FSM coverage
- Functional coverage (SystemVerilog)

### Mixed-Language
- Compile VHDL and Verilog separately
- Use proper interface binding
- Handle type conversions
- Configure library order
- Test boundary conditions

## Dependencies

- Simulator CLI integration
- Waveform viewer knowledge
- Coverage analysis tools

let-fate-decide

Included

Draws the 12 Houses of the Zodiac Tarot spread to inject entropy into planning when prompts are vague, ambiguous, or casually delegated. Interprets the spread to guide next steps. Use when the user says 'let fate decide', 'YOLO', 'whatever', 'idk', or other nonchalant phrases, makes Yu-Gi-Oh references, or when you are about to arbitrarily pick between multiple reasonable approaches. Prefer over ask-questions-if-underspecified when the user's tone is casual or playful rather than precision-seeking.
