Single Module Author

From spec to
RTL & verification

SiliCode runs an end-to-end author flow for one block: generate RTL and a matching testbench, optionally review with reflection, then verify the design — so you iterate from prose, not boilerplate.

Author pipeline

What happens after you submit a single-module specification.

1

Specify

Describe one block: interfaces, behavior, and what you want verified.

2

Generate RTL

Produce Verilog or SystemVerilog for that module from your spec and conversation.

3

Testbench & verify

Generate a matching testbench and run verification when auto-verify is enabled.

4

Artifacts

Download RTL, benches, and logs for your own toolchain.

Example prompt

Illustrative only — real outputs depend on your specification, settings, and model.

“8-bit synchronous up-counter with active-low asynchronous reset, enable hold when disabled, and overflow flag. Target FPGA-style RTL with a simple testbench that checks reset, enable, and rollover.”

Capabilities

Tied to the Single Module Author workflow in the app today

End-to-end single block

One natural-language spec drives RTL, an automatic testbench, and optional verification. Use Agent mode for a straight run, or Plan mode to answer clarifying questions first — this is not multi-module hierarchy planning.

RTL generation

Generate Verilog or SystemVerilog aligned to your description; refine through follow-up messages as constraints tighten.

Automated verification

Automated testbench flows and verification runs help catch functional issues early instead of only reviewing code by eye.

Optional assists & exports

Toggle reflection, web search, code RAG, IP hints, and auto-verify when your deployment supports them. Pull down RTL and test collateral for synthesis and signoff tools you already use.

How it works

Three steps you drive in the Single Module Generator

1

Describe the module

Write interfaces, timing intent, and functional behavior in natural language — enough detail for RTL and what you want the testbench to check.

2

Generate

Run Generate: optional Plan-mode Q&A first, then RTL and testbench. Turn on toggles like reflection, search, or RAG if you need them.

3

Verify & export

With auto-verify enabled, review verification results in the run; download RTL and logs for your environment.

FAQ

Straight answers for teams evaluating the workflow

SiliCode can require an administrator to verify new users before workflow access. You will see a pending notice until approval completes.

SiliCode generates a matching testbench and can run automated verification as part of the Single Module Author workflow.

The product experience today centers on the Single Module workflow: one block, one author loop. Hierarchical multi-module planning and integration are separate and not what this page describes.

No AI-generated RTL should skip your normal review, lint, formal, and signoff process. SiliCode accelerates drafting and test iteration; ownership of quality stays with your team.

The app uses authenticated sessions and API access patterns suitable for team deployments. Treat prompts and generated code like internal IP; use deployment policies that match your security requirements.

Try SiliCode on your next block

Create an account, open the Single Module workflow once an administrator enables access, and author RTL from your spec.
