Waveform Viewer For XSchem

Recently we have worked with Stefan Schippers from XSchem to interface BeSpice Wave with XSchem. XSchem is an open source schematic editor. BeSpice Wave is our graphical waveform viewer. This solution allows to visualize simulation results for SPICE simulations from XSchem. If you are looking for a waveform viewer for…

The PSF and PSFXL file structure

When Cadence Spectre performs a simulation, it writes all simulation results to a directory. This directory can be opened for exploring the simulation results. By default these files are in PSF or PSFXL format. Here we will give a short overview on the PSF and PSFXL file structure. The most…

Analog Regression Testing

Analog regression testing is an essential part of analog design verification. Regression test are used to validate analog behavioral models. They also make sure that a previouslytested analog block still performs as expected after a change. Once analog regression tests have been set up, they can also facilitate other tasks:…

Analog Waveform Comparisons

The algorithms used for analog waveform comparisons can be straightforward. You can simply traverse all curves in a file and find the matching curve in a reference file. Now compute the difference between 2 curves and integrate the result to obtain the absolute error. Dividing this by the norm of…

Reading PSF files from Python

Our waveform parser makes reading PSF files from Python easy. For this purpose we have extended our parser library to a self-contained Python module. This module is implemented as a C/C++ extension to Python. As a consequence you get the full performance of a C/C++ library and the ease of…

Mixed-Signal Waveform Viewer

The new BeSpice Wave version has a new page for digital and mixed-signal data. Digital curves are shown in a specialized plot window. The analog curves are shown in a classical analog plot window.  This makes BeSpice Wave a full mixed-signal waveform viewer. Download our free evaluation version to test…

FSDB Files

Many digital or analog simlators generate FSDB files. FSDB stands for “Fast Signal Data Base”. NOVAS developed this file format to replace VCD (value change dump) files. After a number of acquisitions Synopsys Inc owns FSDB. FSDB files are binary and they make use of data compression. As a consequence…
