draw a transistir diagram from a SPICE .cir file using open source code

@mobasherreza10

Hi there, I have a deep understanding of electronic circuits and the ability to read and interpret complex SPICE files. Moreover, my proficiency in utilizing open source code (including Micro-Cap 12, netlistsvg, Xschem) to draw electric circuit diagrams will be invaluable. More specifically, my expertise in using Python codes in a Windows environment will allow me to effectively process and manipulate the given .CIR files through open-source tools. Over the years, I have garnered considerable experience developing software solutions across various domains. This multidisciplinary knowledge equips me to tackle intricate projects like yours with utmost precision and creativity. Drawing accurate and functional transistor diagrams is critical for microelectronics. My meticulous approach combined with my eye for design ensures that the final output not only adheres to your specifications but is also aesthetically streamlined. Best regards, Mobasher Reza

**Free right now and can start on your SPICE diagram script today** Read through your post and this is very doable in Python on Windows. I would parse the .CIR netlist myself then feed it to netlistsvg or Xschem depending on which handles your file structure cleanly and export the schematic as SVG or PNG. Recent work: built a Python tool that took raw netlists from an EDA export and auto generated clean schematic drawings for a hardware startup, and a parser that converted SPICE subcircuits into JSON for a web based circuit viewer. Send me the example file and I can tell you within an hour which renderer fits best. Can you share it?

You need a Python tool that parses a SPICE .cir netlist and renders a clean transistor schematic automatically on Windows. My plan: parse the netlist with Python, map components and nodes, generate an intermediate format compatible with netlistsvg (strong SVG output, actively maintained, JSON-based), and wrap everything in a simple Python script or GUI. I have hands-on experience with SPICE formats and open-source EDA toolchains. Delivery in 5-7 days after receiving your example file. What component types appear most in your netlists, BJTs, MOSFETs, or mixed?

Hello, Converting a SPICE .CIR netlist into a readable schematic is really two jobs: parsing the netlist (straightforward) and auto-placing/routing the components so the result is actually legible (the hard part). I'd like to address both properly rather than hand you a tangled diagram. My proposed approach: a Python parser that reads the .CIR (devices, nodes, .subckt blocks, models) into a clean internal netlist, then drives Micro-Cap 12 on Windows through its SPICE-netlist-to-schematic translator and automates the export. Python handles parsing, normalisation, batch processing and the final image output, so you can run it on any file in your format without touching the GUI. One note: netlistsvg targets digital netlists (Yosys JSON), so for transistor- level analog circuits it needs custom symbol skins and the layout quality suffers. Xschem works schematic-to-netlist, not the reverse. Micro-Cap 12 is the strongest fit here, and it's free and Windows-native. Two questions so I can scope this accurately: 1. Could you share the example .CIR file and the exact format structure? 2. What output do you need - SVG/PNG image, or an editable schematic file? Happy to run a quick proof of concept on your example file first. Best regards, Florin

The KEY point of this project is not reading a .CIR file, but rebuilding a clear transistor schematic from a netlist that contains connections but no drawing coordinates. The main blocker is automatic layout: transistor pin order, subcircuits, shared nets and wire crossings must be handled correctly for general SPICE files. My approach: • Parse SPICE in Python into components, pins and nets. • Build a graph and generate positions with automatic layout rules. • Map MOS/BJT/R/C sources to Xschem symbols and create .sch/SVG output. • Validate generated connectivity against the original netlist on Windows. I’m comfortable with Python, SPICE parsing and graph-based circuit generation, so I would keep the parser separate from the drawing engine. This makes new .CIR formats and symbols easy to support later. I wish we could discuss more details. Best regard, Rex
