[casper] Doubts about clocking in RFSOC4x2

Hi, I want to change the sampling rate of the ADCs programing the LMX and LMK but I have some doubts about how the clocking scheme is done. The clocking diagram in the RFSoC4x2 reference manual shows that the LMK has one output of 122.88MHz that goes to the pin AN11, another clock of 245.76

Re: [casper] RFSoC4x2 tut_rfdc and tut_spec building only without filename changes

I had the same issue and found that when copying the block or changing the name of the slx doesnt update the internal names (I faced the same problem in some old ROACH models). What I found to work is to open the dialog of the block, modify a parameter and apply the changes, then return the

[casper] Tips to speed up simulation

Hi, I am trying to simulate a model with a correlator using two pfbs+widebands ffts, and currently my biggest problem is the simulation time. For example for ~6000 cycles, the simulation takes up to 15 minutes and I would like to repeat it for like 4000 cases. I am using enabled subsystem with

Re: [casper] Red Pitaya STEMlab 125-14-Z7020

The old 7010 redpitaya also has sata ports, you could sync several of them using that port https://www.koheron.com/blog/2016/11/29/red-pitaya-cluster But the 7010 redpitaya ADCs uses a crystal as its main clock, so you have to move some resistances to feed another clock to the ADCs

Hi Casperiters, When I was playing trying to make a netbooting with the ROACH2 and I issue the command: "run tftpuboot" and making the story short I ended up with no uboot :( Luckily I have access to one xilinx jtag so I was thinking in connecting via xmd to the ppc and send the uboot with

After writing this I think I found it, it was the ddr3_controller.mpd file which overwrites the parameters. I am going to check if now I have more allowable addresses. El vie., 4 sept. 2020 a las 15:08, Sebastian Antonio Jorquera Tapia (< sebastian.jorqu...@ug.uchile.cl>) escribió: >

Hello Casperites, I know that the DRAM block in the ROACH2 is itself a trouble. I have tried to make a model using the blocks in the casper-astro github but I couldn't get any response of the block. In some thread of the mailing list I found the repo of the SMA where I could use the DRAM

Hi casperites, I have been working in project that needs a high SNR In order to achieve that I made a model with 3 decimation steps with factors 16, 8 and 4, to zooming the frequency range [50.625, 52.730]MHz and then put the PFB-FFT combo. The system achieve 100dB of SNR for inputs with the
