TimeGen™ 5 is the newest generation of the timing diagram editor relied on by electrical engineers, FPGA designers, and technical writers to write functional specs since 2003 — available online, or fully installed on your own computer for complete data privacy. Every edit made by clicking and dragging — no syntax to write.
Grab an edge, drag it, and the whole diagram redraws in real time — clocks, buses, and labels stay in sync as you work.
Move edges, labels, and arrows with the mouse — even drag a clock's own waveform to set its phase. TimeGen redraws instantly, no rebuild step.
Model multi-bit buses, hi-Z, weak drive, glitches, and don't-care regions the way your datasheet actually shows them.
Vector out to SVG and PDF, raster out to PNG — every format built for print or the web, sized right the first time.
Ctrl+C copies the diagram straight to your clipboard — paste it directly into Word, PowerPoint, or your spec template. No round-trip.
The biggest change to the editor since it was founded in 2003.
Every clock, signal, and the relationships between them can run completely independently — no shared timebase forced on anything, so designs where nothing lines up on a single clock edge are just as easy to model as ones that do.
Snap an arrow, interval, or text box to a signal or bus edge, and it stays attached — drag that edge later and the annotation moves with it automatically, instead of being left pointing at the wrong spot.
0, 1, high-Z, weak drive, glitches, and Both-High-and-Low — each with ideal or sloped edges, drawn the way the signal actually behaved.
Grab the trace itself and drag left or right — the properties panel tracks the phase slider live as you move it.
SVG and PDF output generated and verified directly against real parsers and renderers.

TimeGen 5 is an interactive visual GUI editor. You click and drag to draw clocks, signals, and buses in real time, with zero syntax or markup to write.
Both. TimeGen 5 runs entirely in your browser on the Free and Professional plans — no installation needed. If you need diagrams to stay entirely on your own machine, the Enterprise plan installs TimeGen 5 to run locally, with nothing sent to our servers. See the full plan comparison for details.
Copy diagrams directly to your clipboard and paste them into Word or PowerPoint as images. Export as PNG (available on all plans) for quick use anywhere, or as vector SVG/PDF (paid plans) — PDF drops straight into LaTeX documents, and both SVG and PDF import natively into Adobe FrameMaker.
No. The free plan (browser-based) has no watermark and includes PNG export. SVG and PDF vector export, plus the downloadable desktop app, are available on paid plans.
Free to start. Full editor, no watermark.
