EZwave to Matlab Save Waveforms and created Buses

[e.fisher]

Hello.

Quick question.
I'm using EZwave to view a mixed mode simulation in Cadence and a 130nm CMOS ST Microelectronics DK.

I'm looking for some tips on exporting EZwave data to csv, or text so I can view it in MATLAB for printing in my thesis.

I now that I can save an EZwave database as a csv or txt file, however this does not save the created buses, formed by the 'Create Bus' tool in EZwave. If I export a .tcl file then I can save the bus creation script for next time, but this is not suitable for MATLAB.

What I want to do it export the entire waveform data base including the created digital buses (decimal radix) so that I can plot in MATLAB.

At the moment I cant find out how to add the created buses to the waveform database.

I can export to jpg or png, however with such shocking quality there is little point!

Thanks.
Ed

PART SOLUTION 1:
I couldn't find how to do this in the end, but!
Best idea is to export the waveform as a png using the highest print setting, on my system this gave me a 3200 by 4300 image, easily ported to .eps etc.

PART SOLUTION 2:
The other solution would be to export your database to cvs, open using MATLAB, create a function that is able to threshold each of the waveforms you are interested in, creating a time array of zeros and ones for each voltage waveform in the bus. This can them be combined with other similarly thresholded waveforms to create a Bitdepth*TimeSeries array. This could then be converted to Decimal*TimeSeries array using the bin2dec function.

For my thesis the MATLAB analysis method was too lengthy for just a few diagrams, if however you need to run statistical analysis or analysis of long strings of simulated output data I'd recommend this approach.
