This is the uniform front end of the package. It supports creation of multi-page schematic diagrams of hierarchical circuits. Its functionality includes full set of manual and automated tools for placement of circuit elements on the diagram and for routing the connections. Front end contains also tools necessary to prepare circuit for simulation and for execution of analyses.

Element Browser is embedded in schematic diagram editor. Efficient library search engine is combined with specially designed database, which enables instant access to most common circuit elements in the library. Default contents of browser database can be easily customized according to user’s preferences. Browsing and searching in the library may be bypassed by assigning hot keys (shortcut keys) to frequently used elements.

Results of analyses are recorded in the form of waveform files and automatically pasted into Waveform Viewer, where they may be examined and printed. Subsequent waveforms are combined in multi-page document and may be presented one by one, tiled or cascaded.

The progress of transient / time domain simulation may be monitored in real time in oscilloscope window or by logic analyzer. Oscilloscope presents waveforms of voltage, current (at four selected test points) or logic states (at 8 selected test points). Logic analyzer presents state of digital signals arranged in 8, 16 or 32 bit words in binary, octal, hexadecimal or decimal form.

SIMWinXP includes extensive library of digital simulation models for Mixed Mode and EDSPice simulators. Simulation models are software modules (DLLs) linked to graphical symbols representing circuit elements on the schematic diagram. User has the option to enhance model library in various ways. The software kit necessary to create MM Simulator models in C-language may be provided on request. Code Models for EDSpice may be created using EDComX, a separate Visionics product. The other way is to define function of a circuit element in VHDL. SIMWinXP includes functions to turn circuit element VHDL definition into simulation model DLL.

This module is used to add new circuit elements to the system library. This task includes creation of graphical symbols for new circuit elements and connecting them with appropriate simulation models. Interface is fully graphical – user creates symbol images from basic primitives like lines, triangles, rectangles, arcs, circles and text strings in various fonts.
