[casper] Large (N 13) biplex FFT does not compile / blackbox

2014-01-29 Thread Price, Daniel
Hi all I am trying to black-box a 2^13 fft_biplex, but it is failing with a non-specific error (reported by: unspecified, error 0001: caught standard exception). It is simulating / updating OK, but the system generator step fails after a few hours. It compiles fine for 2^10, and 2^12 points,

[casper] Timing errors and subsystems

Hi all, Should such software (simulink) features as subsystems and and gotos have any affect on the final circuit created when I build my bof file? I am compiling models on Roach I that use almost all of the available Logic Slices (~97%). That the subsequent build should contain timing

I'm not sure what, if any, difference a subsystem will make to the mapped design (I thought none), but I believe it's the case that changing module names etc. can affect the place and route algorithm's start seed. I seem to remember seeing this mentioned in a Xilinx doc under the heading I've
