Adds capability to independently delay the Auto T/R switching signal by a configurable number of clock ticks, to allow users to precisely align their T/R output with the pipeline delays in the transmitter.
There are two new registers:
FR_ATR_TX_DELAY (7'd2)
FR_ATR_RX_DELAY (7'd3)
...and the corresponding db_base.py methods to set them:
db_base.set_atr_tx_delay(clock_ticks)
db_base.set_atr_rx_delay(clock_ticks)
These methods are inherited by all the daughterboard objects so you can
call them from your scripts as:
subdev.set_atr_tx_delay(...)
...where 'subdev' represents the daughtercard object you're working with.
The FPGA synthesis for the 2 RXHB, 2 TX case expands from 95% to 96%,
with no additional synthesis messages or impact on timing.
