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

Great tool, lot of possibilities to do behavioral modeling, it is easy to add new macromodels based on datasheet data, easy to integrate with frontend tools. I am using it as the backend simulator for XSCHEM. Good support from the developers.
