Open Source Tcl Electronic Design Automation (EDA) Software

Xschem is a schematic capture program, it allows to create a hierarchical representation of circuits with a top down approach . By focusing on interconnections, hierarchy and properties a complex system (IC) can be described in terms of simpler building blocks. A VHDL, Verilog or Spice netlist can be generated from the drawn schematic, allowing the simulation of the circuit. Key feature of the program is its drawing engine written in C and using directly the Xlib drawing primitives; this gives top speed performance, even on very big circuits. I have succesfully managed to simulate complete VLSI projects with this tool, both digital (Verilog / VHDL) and analog (Spice). Schematics can be printed in SVG, PNG, PDF, formats. XSCHEM runs on Linux or other Unix-likes with Xorg server and on Windows with the Cygwin layer and required tools installed. Can be found also on github: https://github.com/StefanSchippers/xschem

TkGate is a event driven digital circuit simulator with a tcl/tk-based graphical editor. TkGate supports a wide range of primitive circuit elements as well as user-defined modules for hierarchical design.

MMTL, the Multilayer Multiconductor Transmission Line 2-D and 2.5-D electromagnetic modeling tool suite, generates transmission parameters and SPICE models from descriptions of electronics interconnect dimensions and materials properties.

Covered is a Verilog code coverage utility using VCD/LXT/FST dumpfiles (or VPI interface) and the design to generate line, toggle, memory, combinational logic, FSM state/arc and assertion coverage report metrics viewable via GUI or ASCII format. This project is ported to github and can be found at: https://github.com/chiphackers/covered

Efficient Symbolic Tools package (EST) is a BDD based tool for the formal verification of concurrent systems. Its advantages are flexibility, portability and an efficient memory management. It runs under different OS, including Linux and Windows 2000/XP.

Platform for advanced open source IP-Core development, i. e. dynamic memory controllers for FPGAs.

Smart GUI to create or update IP-XACT often needed for the IP packaging. It has capability create Bus Definitions from scratch to populate BusDef library. One can create IP-XACT Component, Design or Registers by importing Ip in System Verilog/Verilog-95/VHDL, instantiate Bus Interfaces with proper port maps and attributes as needed. Smart GUI to create IP-XACT Registers, Memory Maps, Address Blocks for IP- has feature to import XLS or Verilog . It has Tcl/Python API support. ipxact2verilog - Generate Verilog module from IP-XACT definition ipxact2vhdlentity - Generate VHDL entity from IP-XACT Component definition verilog2ipxact - Generates IP-XACT definition from Verilog modules vhdl2ipxact - Generates IP-XACT definition from VHDL source ipxactcoherencycheckerverilog / ipxactcoherencycheckervhdl - Validates IP-XACT Component definition with RTL validateipxact - IP-XACT Linting tool

Icarus Verilog Interactive on MacOSX

Elenix is a GNU/Linux distribution dedicated to the needs of management, development, and troubleshooting of electronic circuits.

IC CAD tools, documentation, scripts, and libraries for designing high-performance ICs, including SUE for schematics, MAX for layouts, DPC for datapaths and MCC for megacells. Prebuilt binaries for Linux, Sparc-Solaris, and HP-PA.

This project extends the Proximus development environment to support deployment of AI workloads on next-generation AMD Ryzen™ AI processors, such as the Ryzen™ AI 7 PRO 7840U featured in the Lenovo ThinkPad T14s Gen 4 ,one of the first true AI PCs with an onboard Neural Processing Unit (NPU) capable of 16 TOPS (trillion operations per second). Originally designed for use with Windows 11 Pro, this runtime was further enhanced to work under Linux environments, allowing developers and researchers to fully utilize the AMD AI Engine across both platforms. This cross-platform support is a major innovation, enabling AI workload portability, integration into CI environments, and deployment into Linux-based research and production pipelines.
