# nandsim(4freebsd)

NAND Flash simulator driver

## NAME

**nandsim** – NAND Flash simulator driver

## SYNOPSIS

**device nand** **device nandsim** **options ALQ**

## DESCRIPTION

The **nandsim** is part of the FreeBSD NAND framework nand(4) and can be characterized with the following highlights:

- plugs into the nand(4) framework APIs as if it were a hardware controller (hanging on the nexus bus) with real NAND chips connected to it

- physically part of the kernel code (either statically linked into the kernel image or built as a module)

- controlled with a user space program nandsim(8)

From the user perspective, the **nandsim** allows for imitating ONFI-compliant NAND Flash devices as if they were attached to the system via a virtual controller.

Some **nandsim** features rely on the ability to log contents to a file, which is achieved through the [alq(9)](/alq/9.md) facility.

## SEE ALSO

nand(4), nandsim.conf(5), nandsim(8)

## STANDARDS

Open NAND Flash Interface Working Group (*ONFI*).

## HISTORY

The **nandsim** support first appeared in FreeBSD 10.0.

## AUTHORS

The **nandsim** kernel driver was developed by Grzegorz Bernacki. This manual page was written by Rafal Jaworowski.
