Hi Dave, here (http://www.med.ira.inaf.it/~mattana/casper/) you can find a screenshot and the model file. I did this simulation because I see the same problem on the running project on my ROACH1 board (the pps connected to a led is not blinking anymore). The same simulation is working nominally using the very old 7.1 libraries, I'm using the ska-sa 14.2 toolflow with mlib_devel updated from git on Tue March 5 14:54:36 2013 (commit from wnew).
PPS line in our lab is inverted. Cheers, Andrea 2013/4/3 David MacMahon <dav...@astro.berkeley.edu>: > Hi, Andrea, > > Are you seeing problems in simulation or on actual hardware?
