  1. Hi: I know that .csv files can be imported into the Digital Discovery pattern generator, but I am curious about other formats, and what exactly their syntax/organization needs to look like. Saw the description of pattern export file formats, but nothing on import. We are trying to use prober patterns as starting points, importing into the Digital Discovery pattern generator and then modifying as needed. Many thanks.
  2. Hello, I’m trying to generate the data whose length is over 1000bits by using the pattern generator in Analog discovery 2. I use Microsoft Excel VBA or Python and command FDwfDigitalOutDataSet. But the VBA cannot treat the int data whose length is over 1000bit in binary. Is there any way to transmit the large data to the pattern generator by using VBA or Python? Thanks.
  3. Hi all, I am doing a project on vhdl in which i am trying to display a pattern (like forming an eight) on seven segment display on spartan 3 fpga kit.I have written the vhdl code and simulation works correctly,but the problem is i am not able to write the ucf code (written but may be wrong) required for implementation on spartan 3 kit.I would highly greatful if anyone can help me as to how to write ucf code or modify my vhdl code. Thanks in advance. Regards, Nikhil Singh pattern generator.txt
  4. Hello, I'm using the pattern generator with the output type set to open drain when the output is Z, measuring the output impedance I read almost 5K Ohm, What could be the problem?
  5. Hello. I’m trying to generate the custom data by using pattern generator in Analog Discovery 2. Although I set the digital output mode as custom, the output data is depend on the setting of the FDwfDigitalOutCounterInitSet. For example, I try this code and the custom data is not come from the pattern generator. rg(0) = &HAFAFAFAF FDwfDigitalOutTypeSet(hdwf, 7, 1) FDwfDigitalOutDataSet(hdwf, 7, rg(0), 32) Then I add the FDwfDigitalOutCounterInitSet and the output data is successfully generated. rg(0) = &HAFAFAFAF FDwfDigitalOutTypeSet(hdwf, 7, 1) FDwfDigitalOutCounterInitSet(hdwf, 7, 1, 10) FDwfDigitalOutDataSet(hdwf, 7, rg(0), 32) What does the FDwfDigitalOutCounterInitSet mean when the output mode is custom?
