Question 1

What is SiliFlow?

Accepted Answer

SiliFlow is a unified, zero-setup desktop IDE for Verilog and SystemVerilog RTL design, combining simulation, embedded waveforms, Yosys synthesis, STA timing, CDC/RDC verification, register map generation, and interactive schematics without separate license daemons or shell scripts.

Question 2

Is SiliFlow free for students and learners?

Accepted Answer

Yes. SiliFlow is 100% free forever for students, learners, and hobbyists. There are zero license servers, zero dongles, and no setup barriers.

Question 3

What operating systems does SiliFlow support?

Accepted Answer

SiliFlow runs natively on 64-bit Windows 10 and 11, macOS (both Apple Silicon M-series and Intel), and Linux distributions including Ubuntu, Debian, Fedora, and Arch.

Question 4

How does SiliFlow differ from traditional EDA tools?

Accepted Answer

Traditional EDA requires multi-gigabyte commercial suite installs, license servers, or stitching together CLI tools like Icarus Verilog and GTKWave with shell scripts. SiliFlow integrates open-source EDA engines (Icarus Verilog, Verilator, Slang, Yosys, and wellen waveforms) into a native Tauri v2 desktop window with Monaco split panes, 350ms merged lint diagnostics, STA timing, CDC/RDC analysis, and interactive schematics.

Question 5

What is the 5-phase student roadmap from RTL to GDSII?

Accepted Answer

The student learning curriculum consists of 5 progressive phases: 1) Digital Logic & Synthesizable RTL, 2) Simulation & Testbench Verification, 3) Logic Synthesis & Technology Mapping, 4) Static Timing (STA) & Clock Domain Crossing (CDC), and 5) Physical Design & GDSII tapeout.

Question 6

Does SiliFlow upload my HDL code or netlists to the cloud?

Accepted Answer

No. SiliFlow operates with 100% local privacy. All compilation, simulation, waveforms, Yosys gate synthesis, STA timing, and CDC/RDC analysis happen locally on your computer with zero cloud transmission.
