Re: [casper] Spectrum issues

Something we've had with PFBs and FFTs is that they don't resize properly if you simply change their length in a design. It may be worth deleting them and putting new ones. On 12 Sep 2015 20:03, "Danny Price" wrote: > Hi Michael > > I always blame the sync gen first! I’d

Re: [casper] Spectrum issues

Hi Michael I always blame the sync gen first! I’d suggest just sending out a single pulse to reset the logic, not a heartbeat, at least to begin with, to rule this out. Jack’s suggestion that it might be the addressing of the shared BRAM is definitely a possibility too. It’s very easy for

Re: [casper] Spectrum issues

Hi Michael, Are you certain that 1. The snapshot bram address counters have been changed to accommodate the new deeper rams. If not they will wrap and never write to the lower part of the ram. 2. Whatever controls the valid signal to the shared brams has been modified so that valid goes high for

[casper] Spectrum issues

Hi everyone, I'm having quite a lot of trouble getting large-ish designs (16k channels) to produce spectra. The spectra that are being produced are quite strange. I've provided links below to a few examples. The first link is the spectrum produced by the unmodified tut3 model (except for the
