Qucs - roadmap

• Stage 5 - Design realization, production, verification.



• Layout editor for PCB and chip.
• Layout tools: DRC, ERC, LVS, ...
• Monte Carlo simulation (device mismatch and process mismatch) based on real technology data.
• Automated data aquisition from measurement equipment; easy to use measurement setups.


• Stage 4 - Implementation of industry standard device models.



• Implementation of BSIM series.
• Implementation of HICUM.
• Implementation of MEXTRAM.
• Implementation of VBIC.
• Implementation of EPFL-EKV.


• Stage 3 - Support for more design- and synthesis tools.



• Attenuator design tool.
• Smith-Chart tool for noise and power matching.
• Filter synthesis tool.
• Improve interaction with other software (data conversion).
• Optimizer -- currently using ASCO.
• Transmission line calculator.
• Device model and subcircuit library manager.


• Stage 2 - Implementation of powerful circuit analysis tools.



• EM field simulator.
• Transient simulation using convolution for devices defined in the frequency domain.
• Digital simulation.
• Improvements in the GUI regarding usability and design.
• Large signal S-parameter simulation (LSSP) based on harmonic balance.
• Symbolically defined devices.
• Verilog-AMS interface.


• Stage 1 - Setup a simple GUI and a simulator.



• Support for multiple languages.
• Support for standard types of simulations. Each of them implemented in the simulation backend. Communication between GUI and simulator using files or pipes.
• S-Parameter
• AC
• DC
• Transient
• Harmonic Balance
• AC Noise
• S-Parameter Noise
• Create data representation visualisations (diagrams).
• Implement an easy to use schematic editor.

Green text is currently worked on or even finished.
Blue text is future work.

• model of microstrip cross junction
• writing tutorials about how to use Qucs or design guides, see here for details
• import/export filters for datasets, netlists schematics of other EDA software
• creation of example schematics
• maintenance of the Debian package on a regular basis
• variable step-size coefficients for Adams-Bashford (implicit multi-step integrator)
• paint logos and icons for the GUI
• checking Qucs to compile and run on a variety of systems and platforms
• translation of the GUI and the internal help system
• filter transformations: LC filters to microstrip and/or active filters
• coplanar models for non-zero metalization thickness
• publications and/or help for harmonic balance noise analysis
• EM field simulator (something like ADS Momentum)
• synthesis tools, e.g. attenuators, active filters
• implementation of transmission lines for transient simulation
• implementations of non-linear models like MOSFETs
• digital simulation engine via VHDL -- decided to use FreeHDL for now
• regression test framework and initial test cases for the simulation engine
• maintenance of the FreeBSD (*BSD) package
