Robert Jördens 219dfd8984 rtio: add one register level for rio and rio_phy resets 
* This should give Vivado some wiggle room during PnR.
* It needs three new clock domains which is ugly. But since
AsyncResetSynchronizer can only drive clock domains resets directly
there seems to be no other way to add one register level currently.

Sebastien Bourdeauducq 832fb139a0 Revert "conda: use new noarch system for board packages as well" 
Never missing an opportunity to be awful, conda helps itself with the .fbi files and merrily patches the strings inside them that contain paths resembling the conda build folder, resulting of course in corrupption and CRC errors.

This reverts commit c856b22579.

Robert Jördens 315338fca9 test/sawg: test HBF overshoot, fix sim patching 2017-06-12 20:35:47 +02:00
Robert Jördens 9a8a7b9102 sawg: handle clipping interpolator 
* give 1 bit headroom to interpolator to handle overshoot
* fix Config limiter widths (NFC)
* move clipper to behind the HBF to correctly shield DUC

This leaves a factor of two headroom for the sum of the following
effects:

  * HBF overshoot (~15 % of the step)
  * A1/A2 DDS sum

While this is technically not sufficient and can still lead to
overflows, it is unlikely that one would trigger those. It would require
doing large amplitude A1, large amplitude A2 and additionally doing
amplitude/phase jumps that would overshoot the HBF. No sane person would
try that, right?

closes #743
