Loggin simulation data to text file

I have a simulation with signed 16b input and output. I would like to log the simulation data to an ascii text file for post processing in matlab. Should be a simple way to do this but I can't find it. Seem some references in docs related to tbl format but no details.

Also is it possible to bypass the waveform editor and generate the Quartus simulation file in a text based format? I thought about editing the vwf in a text editor but it can be cumbersome.

Any suggestions would be appreciated.

Tony

    My suggestion is to use ModelSim. It supports e. g. textio in VHDL textbenches, allowing to read stimulus data and write results.

    Thanks for the suggestion. I was trying to avoid the learning curve associated with modelsim but it doesn't look like I have any other choice.

    I have tried to download the free version of modelsim from Altera but no luck. Just keeps emailing me a license for Quartus. Downloading and executing the model code just gives me license errors.

    Anybody have any luck with installing the free version of modelsim with Quartus?

    Thanks

    Hello,

    I can't help with ModelSim Altera cause I'm using a full license version. Regarding Quartus simulator options, *.vwf actually is a text format, it should be able to generate stimulus from external data. But I don't see an opion for simulated waveform export, except that functional simulation output could be exported in a VHDL testbench as expected waveform.

    Simulated waveform apparently isn't written to disk in a readable format.

    Regards,
