How to print signal tap graphics?

Question

Moin,

I'm using QII6.1. Attached signal tap to view some signals of my design; seems to work ok. Now i want to print the signal forms. When i do so, i only get the possibility to print out 69 (or a subset of them) pages; where normally 67 pages of it are without any interest for me, and on 2 pages, exact between them, there's the interesting stuff. :rolleyes:

I haven't found yet any possibility to scale the interesting section to a reasonably size _and_ print this. I'm only able to print with maximum timing resolution; thats currently only approx. 30 Clk Cycles per sheet. Additionaly. the names of the signals would appear only on sheet 1; on sheet 2-69, theres' just an index numbering on the left; no signal names. Any possibility to change this, e.g. a "print exactly what you see in the stp window to one sheet of paper"-function?

Cheers

WK

Unfortunately, there isn't a direct way to do this within the SignalTap window. What you can do as an alternative, is to save the captured data and export it out as either a Vector Waveform File (.vwf) or a graphic file (.jpg or a .bmp). (See http://www.altera.com/literature/hb/qts/qts_qii53009.pdf (http://www.altera.com/literature/hb/qts/qts_qii53009.pdf) - page 54). If you've saved it as a graphic, you can use a graphics editor to crop the region of interest and print to fit to page.

Alternatively, if you've saved it as a *.vwf, open the file with Quartus II. In the waveform editor, you can choose a specific zoom level clicking to View -> Zoom... -> Show range to scale to the samples of interest. From there, you can do a screen caputure of the waveform editor and crop out the waveform using a graphics editor.

Best,

FQ

Moin,

Thanks for the reply; meanwhile i did it as in your alternative solution: I detach the signal-tap window, maximize it, zoom the interesting part, do a screenshot(ctrl-printscreen) and print it with Microsoft Pain(t). Not really straight forward, but sufficient for low level documentation :)

Cheers

Waht would be the best way to read and use this vector wave form file format ?

Quartus II has a waveform viewer. After you've saved off the file, just do a file -> open and search for the .vwf file.

Also, something else you may find useful is the create list feature. Once you have your data captured, select the desired signal groups, right-click and select "create SignalTap II List File" This creates a table of all your selected signals in a text format.

of course, but for documentation, it is necessary to import waveforms to documents.  Currently, I am using TIFFs and screen shots.
