The IDE for silicon.
One open workspace from RTL to GDS2. Built to make chip design easy — without the shelf of separate EDA tools, quotes or license servers.
SiliFlow Studio for Windows, Linux & macOS — drop in raw-source RTL and start simulating. Free for students, hobbyists and learners; one simple license for companies.
SiliFlow replaces the shelf of Synopsys and Cadence point tools with one IDE that walks your design from register transfer logic to layout.
RTL in, waveforms out. Interactive, fast, zero setup.
Elaborate to netlist with timing and area reports.
Ride-along checks on every save.
Reset-domain analysis before it bites.
Scan insertion and coverage in the same flow.
Static timing, annotated onto your source.
Equivalence checks stitched between stages.
The last stop: layout ready for the fab.
SiliFlow is the desktop IDE for chip design — simulate, synthesize, inspect and sign off without leaving one app. It reads your RTL, runs the stage, and shows you the result. All on your machine.
Chip design is a game of knowing exactly where every problem hides. SiliFlow shows each stage's verdict right where you wrote the code.
Press run — buttons, panels and waveforms, not a shell prompt. SiliFlow wires the toolchain, compiles your sources and streams results into a real GUI, instantly, on a small native build. No Makefiles, no Tcl, no marathon setup.
Click a signal in source and jump to that exact transition in the wave viewer — and back again to the line that drove it.
module fifo #( parameter DEPTH = 8); logic [$clog2(DEPTH)-1:0] wp; // design under testendmodule
initial begin $dumpfile("w.fst"); @(posedge full); assert (count == DEPTH);end
Stimulus, golden vectors and checks sit in the same workspace as the modules they exercise.
(* keep = "true" *)logic [15:0] sp;always_ff @(posedge clk) sp <= sp + mem[addr];// lint ✓ · CDC ○ · STA ✓
As you type, the editor already knows what lint, CDC and synthesis think of the code — inline, before you run.
always_ff @(posedge clk) q <= d; // 2.18 ns ✓assign y = a & b; // 0.9 ns ✓// annotated onto your source,// not buried in a 40k-line log
Timing and area reports annotated straight onto your RTL — not buried in a 40,000-line log.
Your netlists and GDS2 never leave your machine. Private by default, online only when you decide.
## project.svp — checked into git+define+DEPTH=8rtl/fifo.svtb/fifo_tb.svh## same tools, same results
One project folder checked into git opens identically for every teammate — same tools, same results.
## one stage at a timestage ▸ sim — ✓ nowstage ▸ synth — nextstage ▸ dft — planned
Try the simulation beta today — synthesis, DFT and signoff land one stage at a time on the public roadmap.
Point tools quote, expire and re-quote. SiliFlow is free for the people learning; companies get one plain license that just stays bought.
No dongles, no segment keys, no IT queue — SiliFlow is free for students, hobbyists and anyone learning the craft. Companies pay one simple license and install in the same minute.
Simulation today; synthesis, DFT, CDC and signoff next — stages that share one project and one GUI. Everything is panels and clicks; the only command line is the one you never have to open.
Your RTL, netlists and GDS2 never upload. The IDE runs native on Windows, Linux and macOS — a compiled core that cold-starts in seconds, sips memory and never blocks your typing. Chip design happens where your data already is.
