Hi all, Is anybody using the Matlab student version with the casper toolflow or know that it's not a good idea? Also, does the 10.1 toolflow work with Matlab R2009a? Thanks, Laura

[casper] large green FFTs

Hello everyone, What's the status of large green FFTs, where large is greater than 2^11? Can they now be reliably synthesized in 10.1? Thanks, Laura

Re: [casper] 2 input fft

Hi Danny, I think what you want is the regular 'fft' with the number of simultaneous inputs set to 0. This gives you two independent streams labels as pol0 and pol1. Cheers, Laura On Thu, Mar 18, 2010 at 11:12 AM, Danny Price danny.pr...@astro.ox.ac.uk wrote: G'day all Does anyone have

[casper] ROACH pulsar spectrometer

Hi everyone, Does anyone have a sense of whether a dual polarization, 800 MHz spectrometer with ~2k channels would fit into a ROACH? I have a test design using the ADC083000 and and two small wideband FFTs. It seems to work in terms of utilization, but I get a crazy number of timing errors. Has

Re: [casper] mlib_devel_10_1 and simulink 7.4

Hi all, For the reasons Andrew mentioned, I think a split in the library should happen as late as possible. While everyone means well, I'm dubious that bugs and features would be back applied to older versions. In my experience using mlib_devel_10_1 with both 10.1 and 11.? on Windows and Linux

Re: [casper] Hang issue when trying to wr/rd a register

As someone that has been using the 10.1 tools for almost two years, I can confirm that they never worked for BEE2s. It would be great if they did, so 7.1 can finally be mothballed forever. Laura On Mon, Jun 21, 2010 at 7:24 PM, David MacMahon dav...@astro.berkeley.edu wrote: On Jun 21, 2010,

Hi Daniel, This error is your initiation into the upper echelons of casper programming. It's our equivalent of the secret handshake... You enter 'D7' into 'Clock pin location' in the System Generator block. Just FYI, many questions are addressed in the mail archive:

Re: [casper] iBOB freezing

Maybe it's overheating?  Do you have a little fan right on the FPGA? We've found that is necessary, even in a proper case.  We cut a hole in the lid and add a fan right over the chip. Interesting idea. I do have a small fan attached to the iBOB heat sink. It was running at the time. The iBOB
