PyOPUS is a Python based platform for very sophisticated circuit optimization and simulation automation. The use of the Python library with the simulator requires a previous SPICE OPUS installation, then refer to the relative tutorial before proceeding. Below we show how to install PyOPUS on windows 7 (64 bit). All the softwares are 32-bit but they work fine on 64-bit. We’ ll have to install the following softwares:
| Python 2.6.4 | Programming language |
| NumPy 1.3.0 | Package for scientific computing with Python |
| SciPy 0.7.1 | Python software for mathematics, science, and engineering |
| MatPlotLib 0.99.1 | Python 2D plotting library |
| wxPython 2.8 | Blending of the wxWidgets C++ class library with Python |
| PyOPUS 0.6 installer | the Windows32 PyOPUS installer |
All these softwares can be downloaded here
The article refers to the softare versions of the table, but the procedure is the same for the updated versions.
Let’s start with the Python installation
the default destination directory is C:Python26
the full features installation requires about 50MegaByte
after the installation we have to add an enviroment variable: Start/Control Panel/System and Security/System/Advanced system settings, now click on Enviroment Variables button.
add to “Path” variable the value “C:Python26”
