Help on matlab "a2d conversion"
Oct 01^st, 2006, 6:50pm

Hi, folks:

I have a waveform from analog simulator, both time and voltage values are stored in a text file. The signal represented is a digital "1,0" stream.

What wanted in matlab processing is the digital information carried in. How to convert them into a stream of one zero digital symbols, without so much useless overhead?

thanks,
Neo

Hi,

are you using the Cadence Simulation Environment? If yes, there is a new interface between Matlab and Cadence's simulation tools: http://www.mathworks.com/products/connections/product_main.html?prod_id=639&prod...
If no, I would try to get a cvs format out of the simulaor and then it is possible to read this data in Matlab or Excel.
You can also write a matlab script, which parses the result file and generates the matlab vectors.
Please specify the tools you are using. Maybe it is then easierer to help.

Kind regards,
haikom

M=dlmread(filename,"",R,C) , where R and C specify the row and column where the upper left corner of the data lies in the file. Defining R and C is useful when you want to extract only the data of your interest.
