# Lambdalib Introduction

Lambdalib is a modular hardware abstraction library which decouples design from the underlying manufacturing target. Lambdalib defines a set of generic functions that get resolved during the target technology mapping stage.

Lambdalib includes the following hardware categories:

| Category                            | Description                           |
|-------------------------------------|---------------------------------------|
|[stdlib](lambdalib/stdlib/rtl)       | Standard cells (inv, nand, ff, ...)
|[auxlib](lambdalib/auxlib/rtl)       | Aux cells can consist of multiple standard cells or physical only cells
|[ramlib](lambdalib/ramlib/rtl)       | Memory (single port, dual port, fifo, ...)
|[iolib](lambdalib/iolib)             | IO cells (bidir, vdd, clamp,...)
|[padring](lambdalib/padring)         | Padring generator
|[vectorlib](lambdalib/vectorlib/rtl) | Vectorized library (mux, isolation)
|[fpgalib](lambdalib/fpgalib/rtl)     | FPGA cells (lut4, ble, clb)

The [Lambdapdk](https://github.com/siliconcompiler/lambdapdk) repository demonstrates implementation of the Lambdalib interfaces across a number of open source process technologies.

Lambdalib has been successfully used in multiple tapeouts using [SiliconCompiler](https://github.com/siliconcompiler/siliconcompiler).

What is bin script confusion?

Bin script confusion

Semantic versions published out of chronological order.

What is a chronological version anomaly?

What is a critical CVE?

Title

Critical CVE

Contains a high severity Common Vulnerability and Exposure (CVE).

What is a CVE?

High CVE

Uses debug, reflection and dynamic code execution features.

What is debug access?

Debug access

The maintainer of the package marked it as deprecated. This could indicate that a single version should not be used, or that the package is no longer maintained and any new vulnerabilities will not be fixed.

What is a deprecated package?

Deprecated

(Experimental) Contains a known deprecated SPDX license exception.

What is a deprecated SPDX exception?

Deprecated SPDX exception

(Experimental) License is deprecated which may have legal implications regarding the package's use.

What is a deprecated license?

Deprecated license

What is a typosquat?

Possible typosquat attack

Dynamic require can indicate the package is performing dangerous or unsafe dynamic code execution.

What is dynamic require?

Dynamic require

Package does not contain any code. It may be removed, is name squatting, or the result of a faulty package publish.

What is an empty package?

What are file dependencies?

File dependency

Accesses the file system, and could potentially read sensitive data.

What is filesystem access?

Filesystem access

Package has a dependency with a floating version range. This can cause issues if the dependency publishes a new major version.

What are wildcard dependencies?

Wildcard dependency

Contains a dependency which resolves to a remote git URL. Dependencies fetched from git URLs are not immutable and can be used to inject untrusted code or reduce the likelihood of a reproducible install.

What are git dependencies?

Git dependency

Contains a dependency which resolves to a GitHub URL. Dependencies fetched from GitHub specifiers are not immutable can be used to inject untrusted code or reduce the likelihood of a reproducible install.

What are GitHub dependencies?

GitHub dependency

AI has identified unusual behaviors that may pose a security risk.

What is an AI-detected potential code anomaly?

AI-detected potential code anomaly

AI has identified this package as a potential typosquat of a more popular package. This suggests that the package may be intentionally mimicking another package's name, description, or other metadata.

What is AI-detected potential typosquatting?
