FMC Delay 1ns 4cha - Gateware Release 2.0
(red) WARNING! White Rabbit support in these bitstreams may be unreliable. The delay functionality is not affected. We are working on a fix (see issue #955).

Release notes
New features:*
- SVEC: official support for White Rabbit on both mezzanines.
- SVEC: squeezed A24 window size to 0x80000 to allow more than 15 cards in a crate.
- All carriers: Support for interrupts through the VIC interrupt controller.
- All carriers: Embedded SDB synthesis information.
- WR Core: Integrated v2.1 of the WR PTP Core HDL and firmware.
- FD Core: WR Core has no physical access to the mezzanine if disabled by the driver.
- FD Core: improvements in DDMTD calibration logic. |
Major fixes:*
- FD Core: ACAM TDC now works in G-Mode (fixes 1.5 ns timestamping errors).
- FD Core: reset ACAM FIFO each sample (prevents timestamp corruption when pulse rate is too high).
- FD Core: shortened arbitration period for the '89295 lines from 32 to 8 ns to achieve 600 ns minimum delay.
- All carriers: reduced drive strength on DELAY_LEN and DELAY_VAL
signals to 4 mA, preventing signal integrity issues (ringing) that
were causing unreliable programming of the '89295 chips.
