71	71		## ePnR
72	72
73	73		[ePnR](https://sourceforge.net/projects/epnr/) is a simple Integrated Circuit (IC) block standard cell placement & routing tool. ePnR currently supports only circuit blocks using equal height standard cells arranged in one or more channels of user configurable length. Standard cells are described in a simple text based library (compliant with eLogSim). Placement follows initially the cell call order in the SPICE like circuit input netlist. However, a placement optimization, aiming at minimum weighted accumulated wire length, by simulated annealing is available. Routing consists of channel routing as first step. If un-routed connections are left, Maze routing can (optionally) be applied. ePnR does not guarantee completely finished routing. However, un-routed connections will be left with rubberband connections and marked start and end points for subsequent manual routing using a third party layout editor. ePnR outputs in CIF 2.0 format readable by e.g. the free KLayout editor. Read more on [ePnR](https://sourceforge.net/projects/epnr/).

220	220		[ULM (Unified Life Models)](http://www.biologie.ens.fr/~legendre/ulm/ulm.html) is an open-source software enabling the simulation and analysis of deterministic and stochastic discrete time dynamical systems for population dynamics modeling. It works natively on Windows, Linux and macOS.
221	221
222	222		Models are described using a simple declaration language, close to the mathematical formulation. The system can be studied interactively by means of simple commands, producing convenient graphics and numerical results.

233	233
234	234		The Forestry Commission and Natural England commissioned a bespoke data collection and presentation tool for calculating the potential for increasing the extent of tree cover across England. It is written entirely in FreePascal using the Lazarus IDE, the LCL and the Graphics32 library. WoodlandCalc is released under the LGPL v2 open source licence and freely available for download from SourceForge. [More info...](http://www.michellcomputing.co.uk/woodlandcalc.html). Application [Download](http://sourceforge.net/projects/woodlandcalc/files/latest/download).

239	239
240	240		[Xoctave](http://www.xoctave.com/) is a Human interface to GNU Octave. Xoctave encapsulates GNU Octave uses pipes and provides extra useful tools to make GNU Octave more easier to use. XOctave is written in Pascal using Lazarus front-end and Free Pascal (aka FPK Pascal) libraries. It uses synedit for syntax highlighting, and uses the Lazarus Component Library (LCL) is a set of visual and non-visual component classes over a Widget toolkit-dependent layer with multi-language support (English-Turkish)
