It provides pre-configured standard cell libraries, I/O libraries, and memory compilers across multiple technology nodes\u2014from 2nm (GT2N) down to 180nm (GF180)\u2014all unified under a single API and integrated directly into the SiliconCompiler build system and Lambdalib hardware abstraction layer.\n\nThe package solves the problem of PDK fragmentation and portability: instead of managing scattered, inconsistent PDK sources or dealing with restrictive commercial licenses, designers get ready-to-use kits with full Verilog models and design-flow integration. Each PDK includes threshold-voltage variants (RVT, LVT, SLVT, etc.), memory macros (SRAM, dual-port, true dual-port configurations), and standard cell categories (AND, OR, NAND, NOR, XOR, MUX, flip-flops, latches, and more). The unified interface enables design portability across technology nodes, making it practical for research, education, and open-source chip projects.","worth_installing":"Yes, if you are designing chips with SiliconCompiler and need open-source PDKs. The package is actively maintained, has no known vulnerabilities, and provides a unified interface across multiple technology nodes. Be aware that Nangate45 (45nm) restricts non-commercial use; other PDKs are fully open. Requires Python 3.10+."},"id":"lambdapdk","links":{"html":"https://skillfed.io/packages/lambdapdk","md":"https://skillfed.io/packages/lambdapdk.md","pypi":"https://pypi.org/project/lambdapdk/"},"maintenance":{"status":"active"},"meta":{"latest_release":"2026-07-10","license_spdx":"Apache-2.0","license_treatment":"permissive","name":"lambdapdk","python_support":"supports_current","summary":"Library of open source Process Design Kits"},"popularity":{"monthly_downloads":1607679,"position":3725,"tier":"top_5000"},"security":{"n_vulnerabilities":0},"version":"0.2.17"}
