Hi Carspers, I have installed again the toolflow for the ROACH-1 in a new workstation with 16 cores and 192GB of RAM memory. I did my first compile test with a big project and the XST generation took more than 5 hours (rather than 1 on the old machine!) while the ISE/EDK stuff took only 40 minutes. I have read some Xilinx issue about permission of the cache directories. I will make other tests on Monday, it seems that the cached files have been generated on the right places, after reading to this mail I WILL DEFINITELY check the Matlab Java Heap !!!!!
Thanks a lot!!!!! Cheers, Andrea 2014-04-12 20:24 GMT+02:00 Matt Strader <[email protected]>: > Thanks, Glenn. Increasing the matlab java heap did the trick. And > thanks, Ryan, for your tip.
