Frequently Asked Questions
Q1: What is AI Verilog Code Explainer?
AI Verilog Code Explainer is a completely free tool that reads your Verilog HDL and produces a step-by-step, beginner-friendly explanation of what the design does, how each block works, and what key lines and signals mean.
Q2: Is AI Verilog Code Explainer completely free to use?
Yes. AI Verilog Code Explainer is completely free to use.
Q3: How do I use AI Verilog Code Explainer to understand an always block and its sensitivity list?
Paste your Verilog into AI Verilog Code Explainer and it will explain the always block’s role (combinational vs sequential), interpret the sensitivity list (or posedge/negedge events), and describe how outputs change over time. The tool is completely free to use.
Q4: Can AI Verilog Code Explainer explain blocking vs non-blocking assignments ( = vs <= )?
Yes. AI Verilog Code Explainer is completely free to use and will describe when blocking or non-blocking assignments are being used, why they matter, and how they affect simulation and hardware behavior.
Q5: Does AI Verilog Code Explainer help identify common Verilog simulation vs synthesis mismatches?
Yes. AI Verilog Code Explainer is completely free to use and can point out common issues like incomplete sensitivity lists, unintended latches, multiple drivers, and reset/clocking patterns that may behave differently in simulation vs synthesis.
Q6: Can AI Verilog Code Explainer break down modules, ports, wires, regs, and bit widths?
Yes. AI Verilog Code Explainer is completely free to use and will explain module interfaces, port directions, data types (wire/reg/logic as applicable), and how vector widths affect arithmetic, comparisons, and truncation/extension.
Q7: Will AI Verilog Code Explainer explain reset logic like async reset or sync reset?
Yes. This tool is completely free to use and will interpret reset polarity (active-high/active-low), whether the reset is asynchronous or synchronous, and how reset impacts registers and outputs.
Q8: Can AI Verilog Code Explainer explain generate blocks, parameters, and localparams?
Yes. AI Verilog Code Explainer is completely free to use and can explain how parameters configure the design, how localparams are derived, and how generate-for/if constructs expand into hardware.
Q9: Does AI Verilog Code Explainer support SystemVerilog, or only Verilog?
AI Verilog Code Explainer is completely free to use and is designed for Verilog code; if you provide SystemVerilog constructs, it will still attempt to explain them, but the best results come from standard Verilog-style syntax and semantics.
Q10: Can I paste a full Verilog project into AI Verilog Code Explainer, or just a single module?
You can paste a single module or multiple related modules. AI Verilog Code Explainer is completely free to use and will explain the structure and relationships it can infer from the provided code, including instantiated submodules when included.
