Re: [casper] Failed to build Casperfpga

Hey Bishnu, I back Jonathon's suggestion - although I'm fairly sure that I got away with installing python3-dev and then just gcc, not the entire build-essentials package, when I recently did a clean install. I also vaguely recall having to manually install Cython too: $python3 -m pip install

Re: [casper] Error message in "Building wheels" when installing casperfpga

Hi Zeck, I vaguely remember having this issue when my version of wheel was not the latest - maybe try update and see? Otherwise I know I have also had to install things like `python3-setuptools` and `python3.8-dev` to get various packages to install correctly when using pip. If that doesn't

Re: [casper] Installing the toolchain

Hi Kaj, To follow on to Mitch's mention of licensing issues, you may want to put together a simple design in Vivado itself and try run synth and implementation there - if it's a licensing issue, the Vivado log will give you more info. Or check the Vivado licence manager to make sure you have the

[casper] RA Instruments using CASPER hardware and tools

Ciao dalla Sardegna, collaborati! I'm hoping to put together a more up-to-date list of instruments that have been built using CASPER hardware and tools. The most current list was compiled in 2016 for the "A Decade of Developing Radio-Astronomy Instrumentation using CASPER Open-Source Technology"

Re: [casper] Question of 'PCORE'、'Share_BRAM' and 'Subsystem' block

Hi Wang, I can't answer the first question, and your third is a bit confusing. Can you send a screenshot of the block you mean? As for the shared_bram - this instantiates bram on hardware that is exposed to the axi/wishbone (depending on the hardware) bus. You can write values ( *vals*) to this

Re: [casper] Upgrade the MATLAB version of mlib_devel

Hi Wang, Depending on what OS version you're using, you may also run into a few library incompatibility issues and missing dependencies for later versions of Matlab. I think getting the toolflow working with later versions of things has been fairly well documented in the mailing list at this

Hi Ashish, So I had some luck playing around with the Xilinx DDS compiler block a few years ago. I must admit my memory on the topic is quite fuzzy and I never really quite figured out how it all works, but I did manage to get an output. I'm assuming that you aren't seeing an output from the

Re: [casper] Problems with installing casperfpga

Hi Wang, It's a bit difficult to see those images because they appear quite small inline (at least for me) but can you try run the install using "python -m pip install casperfpga" rather than just "pip install casperfpga"? If nothing else works, have you tried to build casperfpga using the

Hi Kaj, While I think most people on this mailing list can certainly share your frustrations with getting the toolflow to work, I think it's important to emphasize that this is an open collaboration that many contribute to without it strictly speaking being part of their critical work duties. As

Hey Nikhail, The FFT is a Hermitian function, which means that it has the property: [image: Screenshot from 2022-02-04 08-34-24.png] This principle is used in the real wideband FFT to compute 2 real FFTs using one complex FFT core - this

Hi Xin, Using virtualenv no longer works - people smarter and more knowledgeable than I way know why. As an alternative, you can use "*python3 -m venv*" to create a virtual environment. Sourcing the venv is the same (*source /path/to/venv/bin/activate*), and then install the requirements.txt

[casper] Wideband FFT using Xilinx blocks as primitives

to construct the 2D decomposition of the 1D FFT using Xilinx FFT blocks as primitives. I'm doing some FFT comparisons for my MSc, and would like to include the Xilinx core. I thought it'd be good to check if anyone's already implemented this before embarking on the adventure myself... Morag Brown
