CLUSTER CIRCUITS-LOGIC-DIGITAL · 12 ENTRIES · EARLIEST ENTRY 2005-04-17
digital logic circuit simulators
This cluster consists of desktop applications for designing and simulating digital logic and analog electronic circuits, targeted at students, hobbyists, and educational use. The dated entries span from April 2005 to March 2026 with a thin, sporadic distribution—there are gaps of years between entries, with small batches in 2022–2023 and 2025. Traction as measured by stars is minimal, with issie, Qucs-S, and GTKWave each showing 0 stars, making them the most prominent by this signal.
Entry timeline
ENTRY TIMELINE
Each bar is the month a member carries, which is a creation date where the source published one and a crawl date otherwise. Nothing in the index was found before 11 August 2026, and coverage broadened sharply on 14–15 August, so a bar from then on reports how much we found that month, not how much was built; an earlier bar reports how far back a member's own source dated it — not how long we have been watching.

Two labels per entry, never collapsed into one: how it was built, and who stands behind it. Counted over the 12 listed below. Unlabelled means nothing has decided yet — not that the answer is small.

Ranked by traction, highest first, and paged 20 at a time — this is a window on the cluster, never the whole of it. Ties are broken by a stable id so a product cannot appear on two pages or fall between them. Browse every cluster.
