Viewer Displays Waveforms From Simulations And Test Data

WaveViewer Pro v11.0 can display compressed analog and digital waveforms imported from Verilog, VHDL, SystemC, and SPICE simulation results, as well as from data captured with test equipment such as logic analyzers and oscilloscopes.

Waveforms are saved in SynaptiCAD's proprietary compressed waveform format, BTIM. The BTIM format is typically about 200 times smaller than an equivalent VCD file and loads 500 times faster on subsequent reloads of the waveform data. The compression algorithms operate on both analog and digital data.

The new viewer also includes a PLI application that can directly generate BTIM files from Verilog and VHDL simulators. The BTIM PLI library supports SynaptiCAD VeriLogger Pro, Mentor Graphics ModelSim, Aldec ActiveHDL, Cadence Incisive, and Synopsys VCS.

Users can create "filter files" for selectively loading signals from a waveform file and reordering the signals. Filter files let users see only the waveforms they want to see, without having to select and reorder them every time they run a new simulation. Filter files also allow properties to be attached to the waveforms that are not supported in the native format being imported into WaveViewer (for example, voltage levels can be attached to signals loaded from a VCD file).

SynaptiCAD also offers a commercial version of the viewer, GigaWave Viewer, which allows loading multi-gigabyte files.

AVAILABILITY
SynaptiCAD’s WaveViewer is now available at www.syncad.com.

PRICING
The WaveViewer program is free of charge and is currently available on Windows ME/NT/2000/XP, Linux, Solaris, and HPUX. Optional commercial add-ons include GigaWave capability ($1000), waveform comparison ($1000), and a PSL assertion engine ($1000).
