Silicode - 2026 Pricing, Features, Reviews & Alternatives

SiliCode is a web-based AI platform for RTL development that helps FPGA and ASIC engineers move from hardware requirements to generated code and verification results. It combines HDL generation, testbench creation, simulation, and synthesis reporting in one workflow.

Users describe a module’s functionality, interfaces, timing, and reset behavior in plain language. SiliCode generates Verilog or VHDL and a self-checking testbench, then uses simulation and synthesis feedback to guide refinement. Engineers can inspect and edit the generated RTL and review test results, coverage data, and synthesis reports.

A knowledge base allows users to supply specifications, PDFs, and datasheets as context for generation. The platform supports coding conventions and target-device context, with support for Xilinx, Intel, and Lattice FPGA targets and generic ASIC synthesis workflows.

Agent mode supports autonomous tool execution, while Plan mode lets users review a step-by-step plan before execution. Users can choose different AI models for planning, generation, and verification to balance their workflow needs.

SiliCode is designed for individual hardware engineers and development teams working on RTL modules. By connecting code generation with executable checks and tool feedback, it helps reduce repetitive development tasks and gives engineers evidence to assess their designs before broader integration.
