Analyzing Simulation Results
EZwave Joint Waveform Database (JWDB)
execution is aborted immediately. The numbers of errors and warnings found are displayed at
the end of the first and second step.
Note
After an error has been detected by the analyzer, subsequent error messages may be
unfounded. It is therefore recommended to modify the source file to eliminate the first error
before attempting to interpret the other messages.

EZwave Joint Waveform Database (JWDB)
The EZwave viewer obtains waveform data by loading a database. By default, the EZwave
viewer uses the Joint Waveform DataBase (JWDB) as its input format. Waveform data from the
simulation is stored in the JWDB, where it can be loaded into the EZwave viewer. In the
EZwave viewer, you can view a single database or multiple databases in a single session.
JWDB is a true mixed-signal waveform database. It can hold many different waveform types,
including analog (float, double or complex), histogram, spectral, scatter, Verilog, standard
logic, VHDL char, buses and records, bit, boolean, string, integer (16, 32, or 64 bits) and userdefined
enumerated types. X-values can either be 64-bit integers or double-precision floatingpoint
numbers. It can contain signals from the time and frequency domains, or any other domain
that is needed.
JWDB is also a multi-run database. Waveforms and buses are stored, managed, and analyzed as
compound waveforms. In addition to compound waveforms, JWDB has hierarchies which
enable waveforms to be placed in folders for further data management.
