Overview

ngspice-bin packages NGSpice — the mixed-level / mixed-signal circuit simulator — into a portable, manylinux- compatible binary release for Linux.

Why ngspice-bin?

Upstream NGSpice ships as source code. Building it requires a C toolchain, readline, ncurses, and several other libraries that may not be present (or may be at the wrong version) on every target machine. ngspice-bin provides:

• A pre-built ngspice binary that runs on any Linux system with glibc ≥ 2.17 (manylinux_2_28 build) without any system-level installation.

• All non-standard shared libraries (libreadline, libtinfo, libgomp, libstdc++, libgcc_s) bundled inside the tarball with $ORIGIN-relative RPATHs — nothing extra needs to be on LD_LIBRARY_PATH.

• XSPICE code-level simulation extensions enabled (analog and digital mixed-signal models).

• CIDER numerical device simulation enabled.

• An export.envrc that prepends bin/ to PATH via direnv / IVPM.

Release naming

Each release tarball is named:

ngspice-<image>-<ngspice_version>.<run_id>.tar.gz

For example:

ngspice-manylinux_2_28_x86_64-46.12345678.tar.gz

The <image> field identifies the manylinux base used for the build, giving a clear indication of the minimum glibc requirement.
