The more I use ngspice, the more impressed I am about how versatile this tool is! Granted that this is not the most robust simulator for handling tricky convergences, but other than that, CMC models support, control flow, XSPICE integration and shared library such things make it impressively capable in a very wide range.

Fun, awesome, great support with competent humans and is easy to use with component models. Cheers!
-
Great ngspice! The maintainer solves the user's questions in a timely and accurate manner.
-
Good evolution over time. Existed API to shared library - priceless.
-
Near perfect simulator; no need for LTSpice or MCap. Very good script-performance Documentation/Manual should be restructured to better support learning: - An index is badly needed. - Most information is in, but it is hard to find - Proposal: separate manual-documents for ngspice, tclspice, xspice and CIDRE
