# Gnucap overview The aim of this book is to help people to get started with Gnucap. Gnucap is an open-source circuit simulator, or circuit analysis package (in short: CAP). This book can also be read online at [gitbooks](https://mulder-patrick.gitbook.io/gnucap/) There are other places where you can learn about Gnucap such as: * The [official Gnucap manual](https://www.gnu.org/software/gnucap/gnucap-man.pdf) * the gnucap wiki: * The wiki for [Gnucap examples and tuorials](http://gnucap.org/dokuwiki/doku.php/gnucap:manual:examples) * The Gnucap help mailing list: However, these resources require certain prior knowledge of EDA software tools such as SPICE or stop at questions of running your own simulation flow from start to end. This Gitbook tries to help with that aspects of electrical circuit simulations. Also, if you want to get an overview from the Gnucap developers, there are nice talks on Gnucap in FOSDEM conference talks: * [Gnucap, and analog and mixed signal simulation](https://archive.fosdem.org/2018/schedule/event/cad_gnucap/) * [gnucap - recent work and directions](https://www.youtube.com/watch?v=zyeMORbswKk) ## The Gnucap repository The main Gnucap project page can be found [at the GNU servers](https://www.gnu.org/software/gnucap/gnucap.html). Note, Gnucap has been around for a long time, and not information is up to date, for the latest developments you should track changes on the Gnucap source code. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question. Perform an HTTP GET request on the current page URL with the `ask` query parameter: ``` GET https://mulder-patrick.gitbook.io/gnucap/master.md?ask= ``` The question should be specific, self-contained, and written in natural language. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
